Double-acting design

cities in the United States are shelling out tens of thousands of dollars on more powerful equipment to cut through newer autos. Hydraulic-tool makers, on the other hand, have to put more oomph into their equipment. As a result, the equipment becomes heavier and more painful to the government’s coffers.

Double-acting design, hydraulic tools retraction
Inside relief valve against sudden overload  
Special guide ring design can bear side load no less than 5% permitted load
Standard parts for exchangeable hard-treating slotted sladder
Wet painted surface against corrosion.
Dustproof ring against dust and dirty, to enlong cylinder life, each model equipped with quick connector and dustproof cap.
Competence in working under bad situations, and suitable for long-terms of industry using.

Lifting capacity：20-1000T
Lifting height：120-250mm
Max. working pressure：70MPa
