It has been widely used in ports, steel plants, power stations, ships and garbage treatment, plants, and is used together with tower cranes, ship cranes, ship unloaders, traveling cranes and other types of cranes. The grab has its own hydraulic system. With double oil cylinders drive and high strength steel production. With big closing force, excellent mining properties, and high work efficiency. Hydraulic turning points according to the customers' demand, Without hydraulic rotary excavator grab use the oil cylinder or standby line, don't need to add other hydraulic valve block and line. Rotary hydraulic excavator grab needs add another set of hydraulic valve and pipeline to control, oil cylinder makes the piston protective device.
