Release Time:
Mar 01,2024
In cranes, bridge cranes are the most widely used, almost most factories will have bridge cranes. Unlike car cranes or tower cranes, the main working parts of an ordinary overhead travelling crane are the hoisting mechanism and the large and small car moving mechanism as well as some electrical control systems. In addition to ordinary, there are some applications in special occasions such as hanging iron casting up, coal mine with explosion-proof up and so on, today we mainly talk about the ordinary bridge up the hidden danger of the investigation ideas to

1. Lifting and running mechanism requirements
(1) Inspection of lifting mechanism
In fact, in the daily use of the process, we as the use of units is not necessary to understand the crane is too detailed, after all, the crane inspection and testing, design and installation of repair work need to be qualified units to complete. But as the use of units, we still need to have some timely detection of some basic problems.
Factory bridge up the most likely problem is the failure of the hoisting mechanism, when the electrician often received the crane can not be up and down the overhaul task. One of the most common causes of failure is electrical failure, there are also some stranded wire jamming. Let's do a safety inspection is not necessary to look into the cause, the naked eye to observe whether the up and down smoothly, there is no obvious strand intertwined phenomenon can be.
(2) Inspection of operating mechanism
Bridge up the running mechanism in the bridge above, usually a can move around the size of the car. Large car control bridge up along the fixed track walking, small car control lifting device along the bridge. If there is a driver's room, we safety officers can go up the ladder to see, no driver's room or ladder platform, basically rarely go up.
If you go up, you can look at the drum on the trolley, there will be a lot of wire rope, the naked eye to determine whether there is no obvious intertwining of the wire rope or drum there is no obvious wear cracks. The size of the car will also have some transmission devices, these transmission parts of the protective cover is complete.
When the original electrician, the most common faults of the big car is the running process of the noise or limit faults; the most common faults of the small car is the serious or malfunctioning skidding. We safety officers do not have to repair, but it is best to observe these obvious fault potential, and promptly notify the maintenance.
