Method for preventing loose end of steel wire rope hoist
This year, there has been a major safety accident due to the looseness of the wire rope hoist rope head, which caused the wire rope to break and cause heavy objects to fall, resulting in death. In fact, if you pay more attention to the details, these accidents can be avoided.
In order to prevent loosening of the wire rope head, there are many traditional processes:
1. Weld the tail rope ends together with acetylene or electric welding. In this method, oxygen and acetylene or welding tongs are used on site, which is inconvenient for working at heights, and due to the poor weldability of the wire rope material, the strands that are welded and bonded during vibration are easy to loosen.
2. Use a wire rope clamp to clamp the rope end of the tail rope. This method is fast and convenient, but the design size of the rope clamp is used to ensure the strength of the connection when the two steel ropes are connected. The pretension force when using a single steel rope cannot meet the requirements of the use, which is easy to cause the rope clamp to fall off and prevent the rope strands Further loosening effect is not great.
3. Put the tail rope and the main rope in parallel at the electric hoist, and tightly wind the iron wire with a length of 100-150mm. Although the process is simple and the material cost is low, the operability is relatively strong. It takes a lot of time to waste. When working at heights, there are certain requirements for the skills of the fitter.
believes that wire rope hoist manufacturers can do it according to the traditional process under the premise of meeting the relevant standards. This situation can be avoided. Of course, in the process of use, you also need to do as mentioned above. Don't miss every detail.
