How to conduct safety inspection of electric single girder crane?

 

Single-girder bridge crane is a lifting equipment that is used to lift materials horizontally over workshops, warehouses and stockyards. Because its two ends are located on tall cement pillars or metal supports, it looks like a bridge. The bridge of the single-girder bridge crane runs longitudinally along the tracks laid on the elevated structures on both sides, making full use of the space under the bridge to lift materials without being hindered by ground equipment.

Conducting a safety inspection of an electric single girder crane is an important step in ensuring worker safety. Here are some suggestions for safety inspections of electric single-girder cranes:

 

1. Check whether the appearance of the electric single-girder crane is intact, especially whether the crane's beams, brackets, wire ropes, pulleys, motors, reducers, brakes, electrical equipment and other components have obvious damage, cracks, deformation, rust or looseness, etc. Condition.

 

2. Check whether the working load of the electric single-girder crane meets the requirements. Before use, you should understand the weight and volume of the cargo to ensure that the working load of the crane does not exceed the rated load.

 

3. Check whether the wire rope of the electric single-girder crane is damaged or worn. It is necessary to pay attention to whether the wire rope has broken wires, deformation, uneven lay length, reduced rope diameter, wear, etc. The condition of the wire rope is crucial to the safety of the electric single-girder crane.

 

4. Check whether the brake of the electric single-girder crane is normal. The normal operation of the brake is one of the keys to the safety of electric single-girder cranes. It is necessary to check whether the braking force of the brake is sufficient and whether the brake is sensitive and reliable.

 

5. Check whether the electrical equipment of the electric single-girder crane is normal. It is necessary to check whether the wiring of electrical equipment is firm, whether the contact is good, whether the electrical components are aged or damaged, etc.

 

6. Check whether the safety device of the electric single-girder crane is normal. Safety devices include limiters, heavy-load protectors, stall protectors, etc. It is necessary to check whether these safety devices are working properly to ensure that the electric single-girder crane can automatically shut down in the event of overload or other abnormal conditions.

 

The above are some suggestions for safety inspection of electric single-girder cranes. It should be noted that the operating procedures should be strictly followed when conducting safety inspections. If any problems are found, they should be solved in time. At the same time, regular safety inspections can effectively prevent accidents.
