Gidrolast specialises in the design and manufacture of both Single Acting and Double Acting Telescopic Hydraulic Cylinders. We build both standard catalogue telescopic designs as well as custom application engineered telescopic cylinders. Often a hydraulic cylinder is required to fit into a very tight space and yet provide a stroke that is actually longer than its fully retracted length. A standard rod cylinder cannot do this. A telescopic cylinder, however, can achieve a very long stroke from a compact retracted length. Telescopic cylinders use a series of nested tubular segments sliding within one another (see diagram below). This enables them to provide a very long output stroke from a very short retracted length in one combined actuator. These cylinders are available in 2, 3, 4, 5, or even 6 stages. Most telescoping cylinders are single acting. That means that they extend using hydraulic pressure but then retract using gravity and the mass of the load.

Gidrolast knows heavy trucks. We cut our teeth building hydraulic cylinders for heavy trucks all the way back in 1993. Hydraulic cylinders on trucks are subjected to all forms of contamination that would destroy a poorly designed cylinder. Dirt, grit, rain, salt, tar, chemicals, solvents and cleaning agents all combine to attack the cylinder and its seals. Despite all this, the cylinders are still expected to perform. Cylinder failure means downtime, employee overtime, loss of vehicle availability, less productivity and reduced profit. Gidrolast cylinders are built tough to meet these conditions. They can be found mounted on garbage trucks, dump trucks, belly dumpers, semi end dumpers, boom trucks, knuckle boom loaders, road pavers, concrete mixers, concrete pumps, mobile cranes, tilt beds and tow trucks. Applications include dump cylinders, aerial boom cylinders, compaction cylinders, outrigger cylinders, tilt cylinders, swing cylinders, plough lift cylinders, and more.
