December 2016 - Introducing the 1325B Lubrication and Bentonite Pump
Brownsdale, MN – December 6, 2016 – Akkerman announces the addition of the 1325B Lubrication and Bentonite Pump to its line-up of guided boring lubrication solutions. The 1325B is a hydraulically-driven, high pressure bentonite pump for effective pilot tube lubrication and flushing of cuttings, particularly on long bores and downward slope alignments.
The robust 1325B Lubrication and Bentonite Pump is ideal for guided boring, guided auger boring and soft rock projects using the Rock Drill Adapter and Tri-Hawk® drill bit as well as pressure cleaning applications.
The unit will displace a Marsh Funnel viscosity as high as 50 seconds to flush cuttings with impressive pump flow up to 6 gpm (22.7 L/min) at 2,600 psi (17,926 kPa). The pump meets a full spectrum of project requirements to handle a viscosity range of slurry up to 50 Marsh Funnel seconds.
The 325 gallon (1,230 L) tank features in-tank agitation for aggressive and continuous mixing. The 1325B can independently agitate or agitate and pump to maintain mud viscosity. The 325 gallon (1,230 L) tank presents enough fluid capacity for the average 400-lf. (122 m) bore.
The 1325B is powered by an electric start Kohler® gasoline engine with 14HP (10 kW) and a 1.9 gal (7.3 L) fuel tank.
Not only is the 1325B Lubrication and Bentonite Pump robust, it is also simple, safe and reliable. There are few moving parts, no belts and a shrouded agitator. The stepped platform makes it easy for operators to access or fill the tank. The battery is located inside a plastic housing to eliminate contact with operators. If the pump runs dry, it will not cause internal damage. The unit’s relief valve limits the pump’s maximum pressure and pressure can be adjusted to match tooling requirements. An in-shaft control pendant comes standard and allows operators to vary flow and pressure as needed.
The unit is compact and portable on the project site and sized for quadcon container storage in colder climates with dimensions of 58-in. (1,473 mm) (h) x 88.25-in. (2,241 mm) (l) x 46.5-in. (1,181 mm) (w).
November 2016 - Introducing the Guide Rod Swivel (GRS-50) Family of Cutter Heads
Brownsdale, MN – November 10, 2016 – To achieve guided boring steel casing installations in deep, densely compacted ground and soft rock, Akkerman announces the newest solution in the Guided Boring Machine (GBM) equipment line, the Guide Rod Swivel (GRS-50) family of cutter heads with a universal bearing swivel. The robust GRS-50 family contains four sizes of high thrust bearing upsizing tools able to withstand up to fifty tons of continuous thrust loads on guided boring, guided auger boring, and soft rock pilot tube projects.
Akkerman’s GRS-50 is a versatile choice for an incredible range of pilot tube projects. It is used during guided auger boring to upsize from the pilot tube to the steel casing diameters and also follow the Rock Drill Adapter (RDA) with Tri-Hawk® drill bit tooling in weathered rock conditions. On projects with space constraints, the GRS-50 is also compatible with a 4800 Series Jacking Frame with an Auger Boring Adapter for spoil discharge.*
The GRS-50 Cutter Heads meet the outside diameter of common steel casing pipe in 24-inch (610 mm), 30-inch (762 mm), 36-inch (914 mm) and 42-inch (1,067 mm) diameters. The complete assembly is housed in a reusable, casing sleeve to ensure optimum and consistent performance with all manufacturers’ steel casing. The GRS-50 is an economical solution since the seven-inch bearing swivel is universal to all GRS-50 Cutter Heads and securely bolts onto the cutter head collar. Two seals inside the bearing swivel prevent contaminants from entering the main housing.
The guide shaft extends beyond the face of the cutter head and connects to the last length of pilot tube with a three-inch hex connection to firmly hold the alignment on line and grade. During steel casing installation, the bearing swivel absorbs the rotational torque while the cutter head excavates in a clockwise manner. Excavated spoil enters the cutter head and flows through the auger flighting for removal in the launch shaft.
The durable, carbide gage cutter bit tooling is the same proven design used on Akkerman Tunnel Boring Machines (TBMs). Gage cutter bits along the perimeter of the cutter head create the bore overcut. If an obstacle is encountered, they are situated on collapsible wings that retract into the casing sleeve for pullback. In this event, the guide shaft can quickly reconnect to the hex connection on the pilot tube to resume bore advancement. The gage cutter bit’s round shank allows it to turn as it excavates ground for optimal wear and longevity and if necessary, can be easily replaced.
The complete assembly includes a 24 (610 mm), 30 (762 mm), 36 (914 mm) or 42-inch (1,067 mm) GRS-50 Cutter Head, a Bearing Swivel, an Auger Drive Adapter for six to five-inch lead auger hex connection and a Casing Sleeve. The assembly is 42-inches (1,067 mm) long from tip of the guide shaft to the rear Auger Drive Adapter.
To upsize from the pilot tubes in ground conditions requiring less jacking force, a single or two-step weld-on reaming head remains the appropriate choice for these circumstances.
*The 4800 Series Jacking Frame and Auger Boring Adapter are compatible with the 24 and 30-inch (610, 762 mm) diameter GRS-50 Cutter Heads.

September 2015 - Underground R&D: Akkerman Drill Head Adapter
Brownsdale, MN – September 24, 2015 – Guided Boring Machine (GBM) systems have been used to assist contractors with accurate and extended drives for nearly 15 years. Along the way, Akkerman has developed a series of tooling for a range of geology and upsizing processes to help facilitate longer runs and increase production rates. The variety of project applications seemed limitless, however, when faced with non-displaceable/rock conditions; guided auger boring became unfeasible — until now.
The concept for a steering head adapter to accommodate HDD drilling tools for our pilot tube systems has been years in the making. We’ve brainstormed many possibilities with our equipment representative in Australia. We wanted a product that could aggressively break down the rock and compressed geology found in much of Australia and if all went well, market it worldwide. After deciding on a drill bit tooling option, the adapter design came to fruition and in early September, we had an opportunity to put our prototype to the test.
The Akkerman Drill Head Adapter assembly was used on its inaugural drive on a project in Darwin, Australia for a steel casing installation. The contractor, Queensland Infrastructure Services (QIS), used a GBM 240A and guidance system to install pilot tubes to achieve line and grade accuracy and later upsized to the steel casing diameter with their American Augers® auger boring rig. QIS coupled the adapter with a TriHawk® I Drill Bit from Hammerhead® which chewed its way along the 83-lf. (25m) bore path as a bentonite pump helped to flush the cuttings away. After following along its course through what the crew referred to as “bloody hard" rock, the tooling emerged into a manhole at the exact target. QIS and the owner were thrilled with its success and plan to use it for four more drives on the same project, one that will be significantly longer. Crew members dubbed it “the animal" for the way that it attacked the rock. You can view it in action here.
The Akkerman Drill Head Adapter was revealed in early September at the No Dig Down Under 2015 Gold Coast Show and sparked much interest from attendees. Stateside, ICUEE attendees will be able to see the adapter and with a TriHawk® V Drill bit next week in our outdoor display #K103 in Louisville, KY.

September 2015 - Introducing the P100E Power Pack to the GBM Equipment Family
Brownsdale, MN – September 14, 2015 – The P100E Power Pack was developed to provide contractors with an alternative to address regional requirements of the EPA’s mandate for Tier 4 diesel emission standards. The P100E footprint is comparable to the diesel version in the Power Pack family, and equipped with all the same favored amenities with the added benefits of a low decibel noise level, simplified controls, and reduced maintenance.
The P100E is powered by a 100 HP (75 kW) motor to match the hydraulic requirements of our GBM jacking frames. The electrical motor allows contractors to capitalize on the unit’s useable horsepower, nearly 30% over the diesel version, due to a higher input horsepower to the pump. The Power Pack’s soft start feature makes it possible to couple the unit with a wide array of generators sizes, down to the recommended operating minimum requirement of 125 kW/150 kVa.
The P100E has two, variable volume pumps, each capable of 0-5,000 psi (34,475 mPa) and 0-31 gpm. The pumps facilitate power for rotation and jacking functions to the GBM jacking frame. Hydraulic pressure gauges are adjacent to the pumps, and within easy view for crew members to observe operating pressures.
To contend with the demanding environments where our pipe jacking systems are used, contractors will appreciate the totally enclosed fan-cooled (TEFC) electric motor. The TEFC is a robust and more reliable power source, and has also been integrated into our Tunnel Boring System’s 5200 Pump Unit.
The control panel is located on the container’s door for accessible operation. Power pack start-up can be initiated from the control panel or with the in-shaft pendant. The unit’s three-phase indicator provides a visual indication of correct connections to the generator. The power supply cable is secured to the control panel and conveniently stored on the container door.
The oil cooling system consists of an in-tank control and a multi-plate, air-to-oil cooler to maintain hydraulic operating temperature. Cooling takes place through an electric motor driven fan. In order to maintain an efficient operating temperature, a sensor triggers operation when the oil temperature reaches a pretest value, which is advantageous when the unit is used in cooler climates.
The same ease of use features favored by contractors in our Power Pack family have followed through in the P100E design. The extendable power unit assembly contains hydraulic hose reels, pumps, fluid reservoirs and gauges. Doors at both ends of the container can be opened so operators can walk-through to access the wall mounted tooling storage rack.
The assembly includes six 50-ft. (15 m) hydraulic hose sets to connect to jacking frame functions. New and unique hydraulic hose quick disconnects (QDs) reduce set-up time with a two-turn/two-start thread connection. The QD’s connecting collar holds bearings so the hose can swivel under higher operating pressures which eliminate twisting.
Crew safety was a key factor in the P100E design. The electric motor makes for a low decibel noise level. When used in low-light environments, two interior LED lights plus the white interior illuminate the power pack’s tooling and controls. The e-stop control button is easily accessible and visible from the operational end of the unit.

This combination provides a maximum output torque of 100,000 ft-lbs for auger boring applications. The master ring is positioned between the thrust block and lead casing to adapt to 36-in. (914 mm) casing while the dirt paddles handle the spoil volume. The robust 4800 Series Jacking Frame with 40-in. (1,016 mm) stroke cylinders, makes it possible to install a full length of pilot tube in one push. Alone, this jacking frame will install up to 2 m pipe, but when coupled with varying configurations of 2, 10 and 14-ft. (0.6, 3, 4.3 m) skids extensions, it can install 8, 10 and 20-ft. (2.4, 3, 6 m) pipe lengths.
Guided auger boring continues to be a popular application and Akkerman has the tooling for its variety and success. ICUEE attendees will see the GBM 240A Jacking Frame equipped with a Universal Auger Bore Rig Adapter.

March 2015 - 5200 Pump Unit for the Akkerman Tunnel Boring System
Brownsdale, MN – March 10, 2015 – Akkerman Tunnel Boring Systems have been installing pipe around the world for over 40 years. Akkerman is pleased to introduce the 5200 Pump Unit, the most essential element of the Tunnel Boring System. This flagship product has been improved in several areas while retaining the best qualities of its predecessors, to achieve optimal pipe jacking performance.
The 5200 Pump Unit maximizes the Tunnel Boring System’s capabilities with enhanced functionality to offer the utmost power and precision in many geological circumstances. The unit presents application flexibility with three independent hydraulic sources – two low-pressure sources for the Tunnel Boring Machine (TBM) boring head supply and one high-pressure source for jacking and Intermediate Jacking Stations (IJSs).
Low-pressure hydraulic boring head supply is provided by two, 100 HP (74 kW), totally enclosed fan-cooled (TEFC) electric motors. Each motor features variable displacement piston pumps managed with electronic displacement control, allowing the user to select between 30, 60, 90, or 120 gpm at the flip of a switch. The boring head system supplies 30-120 gpm of oil at 3,000 psi to all Akkerman TBMs or 30-60 gpm at 5,000 psi to Series II TBMs. The advanced 5,000 psi boring head supply is advantageous in demanding ground conditions which require increased cutter torque and greater horsepower in single feed applications.
All jacking and IJSs functions are accomplished by a 12.5 gpm, 8,000 psi capable pump, driven by a 60 HP TEFC electric motor. At 8,000 psi, the jacking system offers 400 tons of jacking force and 30% more pressure for the IJSs. Operators will appreciate the handling of jacking functions with variable pump output and electronic valve actuation.
A 240 gal (908 L) hydraulic tank supplies oil to the pumps and in-tank filtration keeps it free of contaminates. Oil also continuously flows through a dedicated cooling and filtration circuit.
The importance of operator’s safety is evident in the 5200 Pump Unit design. An emergency e-stop is located on the operator’s platform and an optional remote cabled e-stop is available for in-shaft personnel. The control panel on the operator’s station has an enhanced interface and simplified appearance.
The 5200 Pump Unit touts many additional quality features. The unit can be hoisted from a single lift point. The location of the laser slot ensures an unobstructed laser path. Removable, vandal resistant, lockable doors protect the unit during when not in use. Electric is facilitated through a 400-amp, 480-volt, 3-phase connection. The 5200 Pump Unit is 90-in. (2,286 mm) tall, making it ideal for clearance when used with most pit shorting configurations.
The 5200 Pump Unit is interchangeable with all Akkerman Tunnel Boring System components. Contact a sales engineer for more information about this and all Akkerman equipment offerings.

June 2014 - P250D Power Pack
Brownsdale, MN – June 2, 2014 – New to the market, the robust P250D power pack provides plenty of hydraulic power to operate the GBM 4815A jacking frame and larger diameter GBM tooling, while incorporating many ease of use and safety features.
The P250D houses a 250HP (186 kW) engine to match the hydraulic requirements of our largest jacking frame with the engine supply to install up to 48-in. OD (1,219 mm) pipe. The P250D’s six-cylinder diesel engine is liquid-cooled. The 25 gpm (95L/min) cooling circuit makes efficient use of hydraulic oil, maintains low operating temperatures and requires less horsepower (kilowatts). Three load sense, variable piston pumps offer independent operation for jacking, rotation and PCH operation at 0-60 gpm (0-227L/min). The engine’s electric block heater assists starting in cold climates.
The P250D’s power unit assembly is fully operational inside or outside of the container. The power unit assembly can be extended from the container for optimal access to the engine, hose reels, pumps, fluid reservoirs and gauges. With the doors open, operators can walk through to the pilot tube accessories storage area on the container’s wall. The assembly includes 50-ft. (15 m) hydraulic hose sets for jacking frame connections along with a remote control pendant for in-shaft operation.
This P250D is the first of its kind to introduce universal, hydraulic quick disconnect hose connections. The QD’s connecting collar has bearings so the hose can swivel under higher operating pressures to eliminate twisting. The quick disconnects reduce set-up time by 70% due to their unique two-turn/two-start thread connection.
The P250D includes numerous safety features. An e-stop control button is easily accessible from the operational end of the unit and when on, is illuminated for clear visibility in low light. Interior lights shine on the engine, oil reservoir and main doors. The main pump valve features a safety switch, allowing for engine start-up only when the valve is in the full open position. When in operation with the doors closed, the engine’s 70dB level meets tier III standards. Air for the radiator is drawn from the top of the unit forcing engine noise upwards, which also contributes to the unit’s quiet operation.
The P250D is compatible with all GBM jacking frames and accessory tooling.
April 2014 - 1325G Pilot Tube Lubrication Pump
Brownsdale, MN – April 8, 2014 – Successful guided auger boring contractors know that their bore’s accuracy depends on competent pilot tube steering coupled with ground appropriate lubrication. The 1325G Pilot Tube Lubrication Pump enhances these skills while serving as an invaluable, multi-faceted tool.
The 325 gal (1,230 L) tank offers 2,000 psi (13,790 kPa) of pressure at 7 gpm (26.5L/min) of pump flow, providing enough fluid capacity for the average 400-ft. (122m) bore. The tank can be filled with liquid-based polymers to supply lubrication to the pilot tube string or with water for pressure cleaning operations.
The 1325G design is simple and self-contained. Power is provided via direct-drive from engine to pump through a gearbox. The pump’s in-tank agitation quickly and evenly mixes liquid-based polymers and prevents fluid settlement. A relief valve limits the pump’s pressures as necessary. The electric start Kohler engine offers 14HP (10 kW) at 3,600 rpm’s with a 1.8 gal (7L) gas tank capacity. The empty tank assembly weight is just under 1,000 lbs. (454 kg), making the unit highly portable to and on the project site. The unit’s overall dimensions are 52-in. (h) x 89-in. (l) x 50-in. (w), intended to make container storage possible in colder climates.
The 1325G Pilot Tube Lubrication Pump design integrates several safety features. The stepped platform makes it easy for operators to access or fill the 325 gal (L) tank. The battery is located inside a plastic housing to eliminate contact with operators. The lack of moving parts in the tank makes for safe interior access.

September 2013 - Akkerman 4815A GBM Jacking Frame for 8-ft.+ Pipe Lenghts
Brownsdale, MN – September 11, 2013 – Akkerman is pleased to introduce the 4815A jacking frame, the newest addition to the Guided Boring Machine (GBM) line of equipment.
The 4815A design was made essential with GBM projects trending towards 400-ft. + (122 m) length pipe installations. These drives require additional torque and jacking force to advance tooling strings accurately at these lengths. The 4815A jacking frame features 30% more rotational torque than other GBM jacking frame models. Operators using the 4815A have precision, two-speed advancement control options through the gear box for installing GBM tooling. The 100-ton fast and 265-ton slow advance speeds with 100-tons of pull-back force give operators complete control over GBM accessories. The rotational torque operates in two ranges of force, 0-10,500-ft-lbs. and 0-26,000-ft-lbs. to match the tooling requirements. Each torque range offers two speed options with 35 and 50-rpms in the low torque and 23 and 35 rpms in the high torque settings.
The 4815A frame is able to install up to 48-in. (1,219 mm) OD pipe in 8-ft. (2.4 m) lengths. Frames extensions for 10 and 20-ft. (3,6 m) pipe lengths are available. The frame’s 7.5-in. (191 mm) cylinders have a 30-in. (762 mm) stroke and latch on center every 24-inches (610 mm). The 4815A is designed to work out of a minimum 15-ft. (4.6 m) round or square shaft. The frame weighs in at 10,000 lbs. (4,536 kg), nearly half the weight of its predecessor.
The 4815A performs with all existing GBM tooling currently used on 240, 308 and 4812 jacking frames. An optional Power Cutter Head/ Power Reaming Head hydraulic control package is available.
The 4815A GBM jacking frame will be revealed at the ICUEE show in Louisville, KY, October 1-3. 2013.
February 2013 - Eliminator: GBM Tooling for Non-Displaceable Spoils
Brownsdale, MN – February 12, 2013 - A manufacturer and customer collaboration between the City of Edmonton and Akkerman this past fall, proved to be mutually advantageous. In fall of 2012, Akkerman put its new GBM system tooling, the Eliminator through the paces of real world testing in Edmonton, AB Canada. With the Eliminator and the assistance of Akkerman’s crew of accomplished technicians they successfully completed two, 250-foot (76.2 m) drives of 27-inch ID (686 mm) No-Dig clay pipe through non-displaceable clay and clay stone.
The Eliminator is a new 16-inch (406 mm) diameter boring head designed to work with the standard GBM family of Akkerman tools that has been in service since 2001. Named the Eliminator, the cutter head excavates as the lead tooling in soils that are considered too hard for Akkerman pilot tube penetration, therefore eliminating the use of pilot tubes.
The Eliminator is optically guided using typical GBM guidance system components and a target which can be viewed through the string of hollow stem augers. The hollow stem augers are used to drive the cutter bit and transport cuttings back to the launch shaft. Several cutter face bit configurations are available and can be tailored for specific ground conditions. While mining, steering changes are negotiated using three independently controlled, hydraulic shoes. The head is equipped with high pressure jetting nozzles to supply lubrication to the cutter face bit during operation. Once launched, the Eliminator has the ability to be retrieved by pulling it back to the launch shaft. This functionality is extremely beneficial in the event that that there is a change in ground conditions so the operator can make a cutter bit change.
A member of the Akkerman sales team was informed of a project by customer, the City of Edmonton, where pipe installations were required in non-displaceable clay and clay stone. Akkerman and the City of Edmonton viewed this project as an ideal prospect for the Eliminator and soon organized the logistics. Using the Eliminator would prove to be a time saving alternative method for this gravity flow sewer alignment, which was designed as a ring-beam and lagging hand-minded tunnel with a carrier pipe followed by grout fill. The alignment had to maintain an accuracy of at least 2-inches (51 mm) for gravity flow.
The contractor, The City of Edmonton designs, constructs and maintains all of their sanitary and storm water services through their Drainage Services Branch. They began providing pilot tube microtunneling services in 2008, with the addition of an Akkerman Guided Boring Machine (GBM) 4812 jacking system.
An Akkerman technician and engineer arrived on site to assess the project and meet the eight-man crew. They worked inside a 14-foot (4.3 m) diameter shaft at a depth of 46-feet (14 m). The customer’s 4812A jacking frame, powered by a P275 diesel power unit were used to propel the Eliminator through the ground connected to the 16-inch diameter 1-meter long casings and hollow stemmed augers. The installation was a two-pass method. The first pass, consisting of the Eliminator attached to the casings and hollow stemmed augers represented a mere three-day of production time. The second pass, made with the 28.5�? Powered Cutter Head (PCH) outfitted with an increase kit and the final product pipe, was completed in seven days. The tooling was recovered from a 10-foot (3 m) diameter reception shaft. The second drive produced a similar production rates.
August 2012 - Exclusive Notched Thrust Casing Assembly for Efficient Installation
Brownsdale, MN – August 14, 2012 – The Notched Thrust Casing Assembly is an exclusive design, wholly created and engineered by Akkerman. The differentiating points with the new casing include symmetrical notched connections that are secured with a casing collar and common hardware, along with their capacity for extended wear and tear.
The foremost inherent value in this casing is that it ensures improved production. The casings join together by positioning the symmetrical notches into one another and are then secured with a collar for a flush circumference. The collar wraps around the join with common hardware. The casing connections are non-particular, since both ends are the same, so crew members need only orient the auger during positioning. Not only do they quickly connect, their removal is also expedited at the end of the drive. The casing’s multiple wear points also prolong the casing life.
The Notched Thrust Casing Assemblies are available in standard and heavy duty sizes. The standard variety are able to withstand up to 100-tons of jacking force and 50-tons of pullback force and the heavy duty models with bear up to 200-tons of jacking force and 100-tons of pull back force.
The Notched Thrust Casing Assembly can be used with standard Akkerman augers, powered cutter heads and the powered reaming head kit to suit most typical sizes of product pipe for a wide range of geology. Each assembly is commonly packaged in a transportable, heavy duty basket that contributes to site safety and tidiness.
March 2012 - Akkerman Receives MNSHARP Recertification
Brownsdale, MN – March 26, 2012– Akkerman received a recommendation for continued Minnesota Safety and Health Achievement Recognition Program (MN SHARP) certification following a three-day comprehensive site visit last week.
MNSHARP is a Minnesota Occupational Safety and Health Administration (MNOSHA) program of the Minnesota Department of Labor and Industry (MNDLI). MNSHARP recognized companies substantiate exemplary health and safety programs that supersede applicable OSHA standards. Akkerman is one of 39 MNSHARP certified worksites in Minnesota out of 150,000 OSHA regulated companies.
The three-day comprehensive survey included meetings with various personnel plus safety committee members. Two representatives from the MNDLI performed a thorough site inspection in all areas of the manufacturing facility. The site visit concluded with the review of the 58-point evaluation, OSHA Form 33, with recommendations for further safety enrichment.
At the closing meeting, Jeff Wasvick, Occupational Health and Workplace Safety Consultant, stated that he was “impressed when talking with employees and seeing their pride in participation in Akkerman’s safety program�?. He further noted that “It is evident that Akkerman has successfully adopted a safety and health culture that is apparent at all levels in the company.�?
In the past two years since MN SHARP has been in effect, Akkerman has noticed cost savings in terms of lowered medical treatments related to injuries and illnesses. Akkerman has posted only one recordable injury but no loss time injuries for calendar year 2011. Improvements Manager, Gary Medgaarden noted that “We also investigate all near misses that occur. Our goal is to have zero recordable injuries, and the best way to get to zero is to investigate all near misses. In addition, training and enforcement also enhance our program.�?
MNSHARP compliance entitles Akkerman to an exemption from MNOSHA inspections for another three years with the remittance of interim self-evaluation reports.
