SV- WCR4000series hydraulic roller  Cassette and Spanners  suppliers

Features:

The innovative wrench structure without pin joint matches with rapid unloading hydraulic piston and automatic crank 
The 360º×180º rotating hose coupling has no limitation in used space, convenient to operate.
The hydraulic piston and power head have small shape, with light weight, compact structure and small operating radius.
The nut rotation angle in single operation is large and the hydraulic piston has a quick return stroke. The work efficiency is high.
The reactive force is on one straight line, which can decrease the inner torque abrasion
The constant torque output provides the high precision for wrench in the whole working process.
The maintenance is simple and does not need the special tools.
The torque wrench surface has a good corrosion resistant performance after the nickel plating treatment.
All the hollow hydraulic wrenches have copper lining to ensure that the ratchet wheel does not contact with the wall, which can extend the working life.
You can select the various kinds of reduction sleeves to extend the application range.
