Akkerman Inc.

Pipe Jacking alignment accuracy is managed by assessing a laser target bolt’s position on the cutter head, at the centerline of the pipe. The laser is initiated from the pipe laser in the Laser Light Stand behind the jacking frame or pump unit in the launch shaft.

To check the alignment between haul unit transport cycles, the TBM or EBS operator lowers the conveyor to expose the target bolt laser beam. Frequent laser checks will result in fewer steering adjustments. Note, TBM and EBS roll is adjusted by engaging the torque/dirt wings.

The Laser Light Stand features an adjustable frame to position the laser down the centerline of the pipe. The laser box assembly is lockable to prevent tampering with the laser when not in operation.

Akkerman inventories a GEO VL‐70/‐80 Automatic Drifting Laser for our customers’ convenience, suitable for extended length straight tunnels, depending on the tunnel’s ambient conditions.

For proper laser system operation and installation, please refer to the manufacturer’s recommendations.

Testimonials

Super Excavators, Inc. has enjoyed a long partnership with Akkerman over the years. We originally bought a competitor’s microtunnel system and had nothing but problems with quality and service. Finally we called Akkerman and bought their SL36 microtunnel system. Since then we have never looked back. We have bought several other pieces of equipment from Akkerman. From GBM equipment to ABIS to several microtunnel cutting heads. They have been great working with our staff to customize the equipment for our specific needs. We have put their equipment to the test on several projects by pushing the envelope in long drive distances and very difficult ground conditions. The equipment has responded well and together we have made modifications to continue to improve on efficiency. In our business it is necessary to have people their when you need them. Akkerman has done a great job at supplying quality equipment and servicing our needs in a timely matter, helping keep our work on schedule.
