MTBM Lubrication & Jacking Cans
The Akkerman lube and jack can is an extreme asset for any contractor looking to reduce risk on a microtunneling project. These units mount directly behind an Akkerman MTBM head and serve three very distinctive benefits that promote a successful project.
Benefits
- The unit contains a primary stand-alone injection system that ensures proper delivery of pipe lubricant to the annulus directly behind the MTBM. The bentonite injection system is remotely controlled and monitored by the operator or ran in automatic mode.
- The unit contains propulsion jacks housed in a sealed telescopic can that is remotely controlled by the MTBM operator at the surface. This allows smooth and dynamic advancement control of the excavation at the cutterhead in adverse ground conditions and rock.
- An on-board hydraulic power pack not only supplies power to the propulsion cylinders when selected, and the operator can remotely control multiple intermediate jacking stations with lines supplied from the MTBM eliminated high-pressure hydraulic lines from the launch shaft.
FEATURES:
- On‑board powerpack is interchangeable between similar diameter units.
- Lube and Jack Can provides flexibility in the pipe string for line and grade accuracy.
- Reduces pipe jacking loads by properly injecting bentonite lube into the annulus.
- Control software supported by Akkerman Microtunnel Control systems.
- Allows the operator to efficiently control face pressure at the MTBM cutterhead.
- The lube can serves as the primary Automatic Bentonite Injection System, promoting efficient jacking loads along the entire project.
Testimonials
Lithos Engineering is focused on providing tunnel design and construction management for underground construction projects across the United States and has worked with many different tunnel contractors on projects of varying sizes and complexity. I am always happy
to see Akkerman equipment on our project sites and I know we can rely on Akkerman products for a high level of performance and reliability.
I had the pleasure of working with Akkerman on one of our projects for which they designed and constructed a project specific hard rock TBM for a curved water conveyance tunnel high in the Rocky Mountains of Colorado. Akkerman not only provided great solutions and technical support for the project but was a pleasure to work with in a collaborative teaming environment that allowed us to not only reduce project risks but reduce construction costs and schedule. During that project, I visited the Akkerman production facility to inspect the TBM under construction; I was extremely impressed with the Akkerman management, staff, and systems for quality control. I look forward to a long future of working with Akkerman and their products on our tunneling projects.
