Hydraulic cylinders, rams and jacks
These double acting cylinders with piston ends and rods ends having seats to connect hydraulic fluid supply.
They are used to operate particular parts and elements of roof support units, shearers, and other mining machines (roof beam cylinders, sliding canopy cylinders, goaf shield cylinders, side shield cylinders, flap extending cylinders, anchoring cylinders, cantilever extension cylinders, base lifting jacks, advancing rams with a T400.06.143.000 sensor, shearer ranging arm cylinders and others)
Advancing ram with the movement sensor T400.06.143.000
It provides movement of conveyers and controls advancement of roof supports to a prescribed distance with precision movement for every 5 mm of piston stroke.
This ram can be used for advancing the plough supports.
The back stroke jack permits to advance big-sized powered sections.
