Typhoon prevention measures for outdoor cranes

I Possible impacts of typhoons on outdoor cranes

1. Cranes are blown by the wind, run off the track, overturn, and fall into the sea (river).
2. Cranes on the same track collide with each other, causing accidents such as crane collapse, derailment, and damage to steel structures and mechanisms.
3. The trolley cable traction device and trolley machine room shield on the main beam of large gantry cranes are blown over by the wind.
4. Floating objects on open-air cranes are not firmly fixed and are blown down by the wind, causing damage to ground personnel and facilities.
5. When an open-air crane encounters a sudden gust of wind while working, the crane cannot stop and brake, causing the crane to be blown away by the wind. In severe cases, it is blown into the sea (river), causing the machine to be destroyed and people to die.

1. Lock the anchoring device before the typhoon arrives, pull the windproof cable or reinforce the crane.
2. Before the typhoon arrives, put the boom of the boom crane with wire rope luffing to the ground; for tower cranes, keep the slewing brake in the normally open state, and lower the tower crane to a safe height if necessary.
3. Stop lifting operations on typhoon days and lock the brakes of the crane and trolley.
4. Check and clean all unfixed parts on the equipment, and reinforce the railings, protective covers and other parts.
5. After work every day, the lifting machinery should be driven to the designated location for parking, and the lifting machinery should be firmly anchored, and the anti-skid device should be in the anti-skid braking state.
6. The front boom of the ship unloader and the shore container crane should be retracted to reduce the windward area.

1. Repair damaged steel structures and parts.
2. Restore the various mechanisms of the crane to normal working conditions.
3. Perform a performance inspection of the entire crane and put it into operation only after confirming safety.
4. After the typhoon, evaluate the unit's typhoon emergency plan and improve it in a targeted manner.
