Hydraulic valves and cylinders - Import export

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.

Metallurgical equipment all endure heavy-duty service under very demanding environmental conditions. Equipment is subjected to moisture, dirt, saw dust, wood chips, sap and tar and slamming loads. The hydraulic cylinders used on that equipment must meet these challenges day after day. Gidrolast has over 15 decades of experience building hydraulic cylinders for this tough industry. In fact, you could say we cut our teeth in the forestry industry. For our customers, that experience is invaluable. Gidrolast designs cylinders that are able to endure the difficult conditions that metallurgical machinery encounters on a daily basis.

Mining equipment is continually subjected to tortuous conditions that punish hydraulic cylinders. These gruelling conditions include dust, grit, heat, cold and moisture. In addition, the equipment is subject to slamming loads and mechanical impacts. Gidrolast designs and manufactures heavy-duty hydraulic cylinders that endure these very difficult conditions. Gidrolast cylinders can be found on hydraulic equipment in surface and sub-surface mining operations all around the globe. They are installed on dredgers, hydraulic shovels, dump trucks, oversized off-road equipment, tunnel boring machines, ore haulers, ore crushers and aggregate conveyors, to name but a few. We manufacture both rod cylinders and telescopic cylinders, double and single action, in sizes from 12mm (1/2″) up to 700mm (28″) bore.
