Hydraulic wrench, hydraulic tools include: special electric pump, hydraulic wrench,hydraulic jacks, hydraulic bolt tensioning device, hydraulic flange separator, hydraulic nut scissor hydraulic puller, etc.. Hydraulic tool has the advantages of high efficiency,convenient. KERUIDA hydraulic tool has been widely used in steel, shipbuilding,electric power, petroleum, chemical, metallurgy, railway, bridge constructionengineering repair and repair operations around the world and Chinese, also a great service to the building demolition, construction, broken road, water conservancyconstruction situation.

Hydraulic advantage

1, the general use of mineral oil as a working medium, the relative motion can be self-lubricating surface, long service life.

2, light weight, small volume, low inertia, fast reaction speed.

All kinds of element 3, hydraulic transmission, can according to need to beconvenient, flexible layout.

4, can realize the automatic overload protection.

5, control convenient, can realize stepless speed regulation in large range (speed range of 2000:1).

6, it is easy to achieve linear motion.

7, it is easy to realize the automation of the machine, when the electrical and hydraulic control, not only can realize the automatic control of a higher degree of process, and can realize remote control.
