Detailed Answer
Interlock prevents dangerous actions from happening simultaneously: 1. Hoist and lower interlock (cannot both happen); 2. Same-direction trolley and bridge interlock; 3. Crane and ground equipment linkage interlock. Implementation: remote software interlock + receiver relay circuit interlock (dual). The LIDEER LD series has a dual-interlock design; XINGJIA is the same. If the interlock fails, stop using immediately.

Note:Interlock is key to preventing unintended movement; verify it in testing.
