What factors will cause the mobile gantry crane to roll over

time:Oct 19,2016

Rollover is a safety accident during the operation of mobile gantry cranes, the factors that cause the crane machine to roll over are as follows:
1. Overload operation

2. Heavy wind
Because the mobile gantry cranes work outdoors, the wind load is greatly affected, so the mobile gantry crane must have wind-proof device to supply sufficient wind-resistant rollover torque.

3. Slope
The foundation of mobile gantry cranes must be absolutely flat, the slope directly affects the inclination, the greater slope, the more likely to cause rollover.

4. The inertia of the heavy objects being lifted
During the lifting, once sudden brake, due to the inertia, a dynamic load is formed, and the mobile gantry crane will be prone to rollover accidents.
