High Tonnage Double Acting Hydraulic Cylinders

High Tonnage Double Acting Hydraulic Cylinders1.Describe:High pressure hydraulic jack is powered by ZB series of high pressure electric oil pump, the function for oil pressure rebound, overflow, it is designed a safe protect pressurizer, it can protect emergent over pressure, especial construction can protect cylinder. Hydraulic cylinder can bear partial loading is 5% of rated pressure. High pressure alloy cylinder is very durable, especially in the larger project, it is easily to be operated and control. It can be used for lifting heavy machine, bridge project, hydraulic engineering, harbour construction and other equipment. It has large output, light weight, remote control and other advantages, it can match with our high pressure oil pump, it can reach jack, push, pull and extrusion and kinds of working.2. Features1. Integral stop ring provides piston blow-out protection2. Double-acting for positive retraction3. Baked enamel outside finish and plated pistons provide superior corrosion resistance4. Safety valve in retract side of cylinder helps to prevent damage in case of accidental over-pressurization5. Interchangeable, hardened grooved saddles are standard6.
