Detailed Answer
Grab opening/closing interlock: grab open/close is automatically coordinated with hoisting actions (open bucket → lower → close bucket → hoist), reducing operator action complexity and improving efficiency. The remote control implements interlock via multi-key combination/logic programming. Lideral LD-10DK/12DK support grab interlock programming; Xingjia proportional models support joystick interlock.
| Principle | Auto coordination of open/close |
| Efficiency | Reduce misoperation |
| Support | LD-10DK+ |
Note:Grab interlock logic must be debugged per the actual mechanism of the ship unloader.
