Main Jacking Cylinder HT-T-MJC-Series
This 2-Stage, fully telescopic Main Jacking Cylinder is used for Pipe-jacking and Microtunnelling.
The specially designed cylinder is equipped with mounting plates that allow for deflection in all directions. No intermediate support is required over the full stroke. The telescopic cylinder is mounted between the Thrustwall and the Pushring by means of bolts in order to allow easy and quick assembly and to reduce rig-up time to a minimum.

Other version can be constructed and built on request.
|Type||Thrust (at 500 Bar)||Length (retracted)||Stroke|
|HT-T-IHC-330-350||330 kN||635 mm||350 mm|
|HT-T-IHC-646-350||646 kN||635 mm||350 mm|

Refurbishment and Upcycling
HEYNCK® distinguish between Refurbishment and Upcycling.
During a refurbishment HEYNCK® performs repair work tailored to suit the client. Afterwards, the cylinders can be used in the best way possible while keeping repair costs low.
Upcycling is repair work at the highest quality possible. All cylinders are completely dismantled and then re-assembled strictly reusing only parts that are flawless. In some cases parts are replaced with higher grade material than used when the cylinders were manufactured originally. Any Upcycled cylinder is as good as a new one or sometimes ever better. Therefore, HEYNCK® offer the same warranty for Upcycled and new cylinders.
