Product Name: Electric Hydraulic rectangular grab

Working principle:

1. Open cycle: When the motor is running, the hydraulic pump will pump the hydraulic oil from the fuel tank, when the grab needs to open, hydraulic oil through a one-way valve through the pressure pipe to the cylinder of the rod cavity, at the same time, pressure oil will be hydraulic control valve back to the oil mouth open, oil cylinder without rod cavity oil inflow back to the tubing, through the return oil filter back to the tank. While the piston rod is retracted to the cylinder barrel, the grab is gradually opened.

When the motor is closed, the one-way valve and the hydraulic control valve can lock the oil cylinder to prevent the grab from closing automatically.

2. Closed cycle: When the motor is running, the hydraulic pump will pump into the pressure pipe, operate the electric control box, the hydraulic oil through the one-way valve and pressure pipe into the cylinder without rod cavity. At the same time, the pressure oil will be the road liquid control one-way valve is opened, so that the cylinder has a rod cavity hydraulic oil through the pressure pipe and hydraulic control one-way valve, through the back of the tubing and oil filter, flow back to the fuel tank.
