**Working Principle:**
**Closing Cycle:**
When the grab opens, the moving plate connects with the top roof beam and separates from the lower one. The hydraulic system opens, and the piston is pulled out. When the crane hook lowers, the moving plate moves down along with the piston. Upon touching the stroke switch, the electromagnetic valve stops the hydraulic oil flow, and the grab closes.
**Opening Cycle:**
Pressing the remote control sends a signal to the receiver, opening the hydraulic circuit. Gravity causes the hydraulic vat to extend, separating the lower roof beam from the moving plate, allowing the grab to open.
