Hydraulic Elements & Systems Plc (HES) constructs, produces and maintains hydraulic cylinders. HES works mainly on customers’ requirements with specified parameters, quantity and terms of delivery.

PISTON CYLINDERS – single-acting and double-acting (with or without damping at the end of the stroke) with diameter of the piston rod from 30 mm to 300 mm and maximum stroke length of 2500 mm.

PLUNGER CYLINDERS – with diameter of the plunger from 20 mm to 250 mm and maximum stroke length of 3000 mm.

TELESCOPIC CYLINDERS – single-acting up to 8 levels with maximum stroke length of 8000 mm; double-acting up to 3 levels with maximum stroke length of 4500 mm.

RACK CYLINDERS – with diameter of the piston up to 100 mm and maximum stroke length of 500 mm.

The quality of the sealings ensures the dependability of the products and maximum working pressure of 32 MPa. The plungers and the piston rods are hard chromium-plated with standard layer depth from 0.025 mm to 0.035 mm and hardness of 800-1100 HV. On customer demand, rods may be produced with a thicker chromium layer, made of stainless steel and heat-treated.

The products of HES are used in the production of:
• Material handling equipment (cranes, fork-lifts, dumpers);
• Agricultural machines (harvesters, tractors);
• Construction machines (excavators, bulldozers, front shovels, concrete mixers, lifting platforms);
• Machines for forestry industry;
• Communal transport machines, etc.
