The input shaft end of the motor cannot shake the entire row of brackets → check whether the linear actuators have reversed linear actutors → if the linear actuators are installed reversely, the same row of linear actuators will have opposite telescopic directions → need to remove the reversely installed linear actuators and replace them in the same direction.
There are cracks or direct disconnection in the forward pull → the limit impact of the ordinary forward pull is 20000N → much higher than the actual working condition → check whether the upper and lower mounting seats of the linear actuators are on the same horizontal plane → if the linear actuatoris not on the same level, the linear actuator is subject to lateral force. It will be very large → the upper and lower mounting seats are adjusted to be level
