Detailed Answer
Anti-collision systems (multiple cranes working on the same span) monitor crane spacing, with proximity warnings/automatic slowdown and stop. Remote interlock: remote commands are restricted when anti-collision triggers. LDER and XINGJIA support interfacing with anti-collision systems. With multiple gantry cranes sharing a span, anti-collision interlock is a safety necessity.

| Interlock | Speed limit/stop |
| Necessity | Multiple cranes, one span |
Note:Include anti-collision interlock testing in the monthly safety check.
