    Can the welding hook of the explosion-proof hoist be repaired after wearing?


Description: Among the parts of the explosion-proof hoist, the hook is the main part of the lifting weight. In addition to the lifting weight, it must also bear the impact load when the lifting mechanism starts and brakes. Therefore, the materials used to make hooks should have high strength and impact toughness, and their safety factors are relatively large.

Among the parts of the explosion-proof hoist , the hook is the main part of the lifting weight. In addition to the lifting weight, it also needs to bear the impact load when the lifting mechanism starts and brakes. Therefore, the materials used to make hooks should have high strength and impact toughness, and their safety factors are also relatively large.

工艺规程未颁布之前,无疑是非常正确的。 The Ministry of Machinery Industry once stated clearly: "When the height of the vertical cross section of the hook is greater than 10%, it should be scrapped and repair welding is not allowed." This rule is undoubtedly very correct before the unified welding repair process regulations have been promulgated .

The hook is one of the very important slings in explosion-proof hoist operation. It not only bears the weight of the object, but also bears the impact load during lifting and braking. Therefore, it is very strict. Then continue to use it.

In addition, if the hook is cracked, it will be scrapped in time to avoid unnecessary accidents.

影响企业的正常生产,往往采用补焊的方法来恢复吊钩的安全起吊系数。 However, in some small and medium-sized enterprises, because the unit does not have the ability to manufacture hooks, and there is no spare hook, when the wear of the hook exceeds 10%, in order not to affect the normal production of the enterprise, repair welding is often used Method to restore the safe lifting factor of the hook.

;当然,这种措施并未排除发生事故的可能,我们有必要对补焊法进行科学的分析和研究,进一步验证这种方法的可行性。 Although doing so violates the relevant regulations of the Ministry of Machinery Industry, through the field use of some units for many years, there have not been any accidents caused by repair welding ; of course, this measure does not rule out the possibility of accidents, we have It is necessary to carry out scientific analysis and research on the repair welding method to further verify the feasibility of this method.

Therefore, in the explosion-proof hoist we use, if the hook is seriously worn, repair welding is not allowed to avoid unavoidable harm during use.
