Detailed Answer
A moment limiter is a tower crane overload protection device: it calculates the lifting moment in real time and automatically alarms/cuts the hoist on overload. The remote control links with the moment limiter: when the limiter trips, remote hoist commands are invalid (hard-wired interlock), preventing overload lifts. The LIDEER LD series receiver reserves limiter signal input terminals; XINGJIA is the same.
| Function | Overload protection |
| Linkage | Remote hoist disabled |
| Wiring | Signal input |
Note:When the moment limiter alarms and the remote cannot hoist, that is normal protection.
