Instructions for safe operation of bridge cranes and gantry cranes

Bridge cranes and gantry cranes are widely used in transportation activities and daily industries, especially in ports, railway loading and unloading operations, and shipbuilding processes. Certain problems often occur during the use of cranes Among them, there are relatively many types of faults, mainly including operating mechanisms, lifting mechanisms and brakes.

Although the application environments of bridge and gantry cranes are different, the structures of bridge and gantry cranes are generally the same. Tracks, running mechanisms, cables, and crane cages, etc., because all components will have a certain adverse effect on bridges and gantry cranes, and eventually cause failures during operation, which will have a certain adverse effect on work progress.

Precautions for crane driver operation:

1. During operation, tower crane operators and command personnel must cooperate closely. The commander must be familiar with the performance of the tower crane under command

2. The operator should strictly implement the command signal. If the signal is unclear or wrong, the operator can refuse to execute it.

3. During operation, no personnel are allowed to stay or pass under the heavy objects, and it is strictly forbidden to use tower cranes to lift personnel.

4. Tower crane operators must operate according to the specified lifting performance, and it is forbidden to open the limit to overload objects and lift objects of unknown weight.

5. It is strictly forbidden to use tower cranes to pull, obliquely hang and lift buried objects or heavy objects condensed on the ground. The concrete components or formwork poured on site must be loosened before lifting.

6. The lifting and lowering speed of the tower crane should be uniform, and the left and right rotation should be smooth. Fast and slow and sudden braking are strictly prohibited. When the rotation is not stopped, the reverse action is not allowed.

As important equipment in promoting economic development, bridge cranes and gantry cranes play a very important role in the railway transportation and port transportation industries by ensuring their safe and stable operation. However, various operational failures will inevitably occur in mechanical equipment. Only An in-depth analysis of the fault can better propose corresponding solutions.
