Piling barge cylinders are used for operating ram-cranes on working barges. With these barges, concrete-steel pillars with lengths up to 100 m get rammed in the sea ground used for construction of bridges, quay walls or harbour walls. By the bi-directional working cylinder the mast can be adjusted to different angles to get higher stiffness from the lightly crossed pillars.

The cylinders are certificated according to CCS standard or DNV lifting appliances 2008, DNV standard for certification No. 2.9- hydraulic cylinders. Main features of the cylinders are the Ceraplate rod coating, stainless steel spherical bearing, offshore plastic compound bushings at rod end for automatic locking function and friction and wear optimized Hunger seal and bearing elements. The cylinders are equipped with manifold block providing all safety and load control functions.
