Safe operation of electric hoist bridge crane

The mobility of the machine is very important to improve the efficiency of the crane industry. Compared with machinery, cranes are cumbersome and cumbersome machines, but their work solves the problem of not being able to reach more manpower, thus winning the needs of the enterprise industry, but important issues are placed in front of more crane companies, How to improve the maneuverability of the crane under the premise of performance. As we all know, for the needs of enterprises, the development of the crane industry, mechanical mobility is particularly prominent, which is also an effective guarantee to ensure the efficiency of the crane. To this end, more companies will scale down in the development process, and at the same time, the design will be more scientific and reasonable, especially in terms of performance. Only by creating more flexibility and more flexible performance can the service industry effectively develop demand.

The working level/work type of the electric hoist bridge crane is light A3 and intermediate A5. The working environment temperature of the lifting bridge crane is -20-40 °C. It is forbidden to use electric hoist bridge cranes in environments with flammable, explosive and corrosive media. There are three types of electric hoist bridge cranes: ground handling, wireless operation and operating room operation. There are two operating rooms: open and closed. According to the actual situation, it can be divided into two sides. The entry direction has sides and end faces. The top three.

Electric hoist bridge crane safety operation procedures:

1. Before starting, carefully check whether the mechanical, electrical, wire rope, hook and stopper of the electric hoist are in good condition.

2. Do not overload the crane. Do not hold your hand between the rope and the object when lifting it up. When the suspension rises, it is strictly prevented from hitting the top.

3. When lifting an object, follow the safety procedures of the crane. Be firm when tying and leave a filler at the sharp corners of the item.

4. Start with the traction line electrical switch and the insulation must be good. Press the button correctly and pay attention to the standing position during operation.

5. The monorail electric hoist must be decelerated at or near the end of the track.

6. When using the electric hoist, it cannot be used frequently and frequently reused, otherwise the brake may be heated.

7. Tilting and horizontal dragging are not allowed.

8. It is strictly forbidden to hang in the air for a long time to prevent deformation of the parts.

9. When the electric hoist finds a fault during use, the main power should be cut off immediately.

10. After use, place the electric hoist at a fixed point and raise it to more than 2 meters.

11, often check the electric hoist, find faults or hidden dangers in a timely manner, and record the maintenance situation. The LH electric hoist bridge crane has the advantages of small size, small building clearance, light weight and low wheel pressure.

Check the bridge crane's coupling for looseness or even a "scroll key". Pay attention to the abnormal wear of the elastic rubber ring of the elastic pin coupling, and pay special attention to the gear ring wear of the toothed coupling. Due to the poor mounting accuracy, in the case of a large offset between the two axes, it seems that the entire ring gear will quickly become bald in a short time. If this happens in the hoisting mechanism, it is very likely that a serious accident will occur.
