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
I have used TBM equipment since 1996 for the installing pipes from 1.22 m to 2.44 m of internal diameter, they are very efficient in clays and silts with a high content of humidity.
I have also used GBM systems for driving smaller diameters in soils soft from the Valley of Mexico and are suitable for these conditions.
