Discussion on the causes and hazards of broken lifting chains in stage electric hoists
With the rapid development of the economy and the construction of cities, the development of the lifting industry is becoming increasingly fast, and the use of lifting chains is also becoming more and more widespread. No matter under what circumstances it is used, safety is of utmost importance. Below, the editor will explain to you the reasons that affect the breakage of the lifting chain of the stage electric hoist, as well as the accompanying hazards.
Firstly, rust is a contributing factor to chain breakage. Rust can change the chemical structure of the chain, causing the texture of the chain to become loose, resulting in a decrease in the overall strength and toughness of the chain. The possibility of chain fracture during the process will be greatly increased, and the fracture surface is generally the rusted part.
Secondly, overloading and long-term fatigue use are another contributing factor to chain breakage. Each type of lifting chain has its own rated load, and overloading can easily cause deformation or breakage of the chain.
Once the lifting chain breaks, it is easy to cause harm to goods and personnel, especially during high-altitude lifting. Therefore, it is strictly prohibited for personnel to stand below during lifting to avoid injury. The lifting chain has a safety factor of 4 times and generally does not break without overloading or severe rust.
Effective measures to reduce the wear and tear of the stage electric hoist lifting chain
Crane chains are often used in environments with high load-bearing capacity. During use, excessive wear and tear can have varying degrees of impact on operational safety. To reduce the degree of wear and tear, only two methods are needed:
1. During use and maintenance, apply a thin layer of lubricating oil evenly on its surface, and let it stand for a period of time. After the grease is fully absorbed, use it again to reduce wear.
2. Choose a suitable chain for operation according to actual needs. If any abnormal operation occurs during use, please stop the operation in a timely manner and inspect the lifting chain. This can also achieve the goal of reducing wear and tear.
