1.Structure: The structure is reasonable which minimizes the loss of excavator digging force.
2.Installation: theelectric control switch controls the electromagnetic reversing valve, and the pilot oil pressure of theexcavator is used to push the connector cylinder to rotate the grab hook to achieve the connection and disassembly of the shaft. after installation, the cylinderis self-locking
3.Cylinder: the imported brand nok sealing kit is used, and the quality is muchhigher than other domestic sealing brands, which greatly reduces the probability of oil leakage in the cylinder.
