Electromagnetic suction cup excavator modified hydraulic electromagnetic suction cup has strong adsorption force for

Before starting the hydraulic suction cup,An overflow pipe must be connected.

The overflow pipe sends the excess flow from the input motor back to the oil tank, with the front end connected to the motor and the rear end connected to the oil tank. The overflow pipe needs to be directly returned to the fuel tank without back pressure. be careful:

The overflow pipe cannot be connected in parallel with other return pipes to return to the oil tank

There should be no hydraulic components such as one-way valves that can generate back pressure in the circuit between the overflow pipe and the oil tank.
