MTBM Jacking Frames
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.
FEATURES:
- Keyed thrust cylinders are interchangeable between units to reduce cost.
- Additional thrust cylinders can be added on MT8102K and larger jacking frames to increase capacity for extended drives.
- Curved or flat reaction walls are optional.
- Hydraulic plumbing is efficiently routed for synchronized cylinder operation.
- Auxiliary hydraulics allow quick pullback of the thrust block or operation of portal seal pipe break.
- Hi‑flow return valve enables quick cycle times between thrusts.
- Reaction wall designed for tunnel guidance system placement and tool storage.
- Standard pipe length is 10 ft; extension kits available for pipe sets up to 20 ft.
- Service bays available for TBM projects.
- Frame designed for in‑shaft assembly to reduce crane size requirements.
- Minimum shaft size varies by configuration: 16 ft to 24 ft.

Testimonials
We do not own or use any pipe jacking equipment other than Akkerman. Their equipment has been used to jack RCP pipe, Hobas pipe & Steel casing from lengths as short as 50LF to distances up to 1000LF. From diameters starting at 42″ ID up to 108″ ID US
Not all of our work is constructed trouble free. Akkerman has always helped us through any issue we may have and treated us fairly. We have been impressed with Akkerman’s growth over the years and have long term friends there as well.
