Akkerman MTBM jacking frames are built to deliver high thrust capacity while minimizing launch shaft requirements. The multi-cylinders keyhole design applies thrust loads through the center of the pipe axis minimizing stress concentration on pipe joints. MTBM jacking frames are remotely controlled from the surface or can be pendent controlled from a power pack and used for other pipejacking methods with a service bay attachment.
- Keyed thrust cylinders are interchangeable between each unit reducing cost.
- Additional thrust cylinders can be added on MT8102K and larger jacking frames to increase thrust capacity for extended drives.
- Curved or Flat reaction walls are optional.
- Hydraulic plumbing is efficiently routed and provided synchronized operation of cylinders.
- Auxiliary hydraulics allow quick pullback of thrust block or operation and portal seal pipe break.
- Hi-Flow return valve allows quick cycle times between thrusting.
- Reaction wall designed for tunnel guidance system placement and tool storage.
- Standard pipe length is 10-ft. Extension kits available up to 20-ft pipe sets.
- Service bays available for TBM projects.
- Frame designed for in-shaft assembly to reduce crane size requirement.
- Minimum Shaft Size: Varies on configuration. 16-ft to 24-ft

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.
