Problems solved by technology

[0002] The spring spreader is generally used in lifting tools for large items because it can bear a large weight. However, for some heavy items, the amplitude of the spreader will increase, which will affect its internal structure. After long-term use, the noise will increase. Therefore, the high elasticity requirements and large bearing capacity of the spreader are even more significant

Abstract

The invention relates to an elastic hanger, which includes lifting lugs, the lifting lugs are fixed on the fixing part through nuts, the fixing part is connected with a shock-absorbing spring device, a reinforcing rod is inserted in the shock-absorbing spring device, and the bottom of the reinforcing rod is provided with a first thread segment , a matching spreader frame is fixed on the first threaded section, a weighing device is arranged on the spreader frame, a matching connecting rod is provided at the end of the spreading frame, a second threaded section is provided at the top of the connecting rod, and the connecting rod Ends attach to hooks. The invention is simple in structure, stable and firm, adopts a shock-absorbing spring device, has small resonance amplitude, long life, and low noise. The weighing device can better display the lifting weight, avoid exceeding the acceptable range, wide application range, and can withstand high pressure , low cost, and increase comprehensive economic benefits.

Description

technical field [0001] In particular, the invention relates to an elastic sling. Background technique [0002] Spring spreaders are generally used in lifting tools for large items because they can bear a lot of weight. However, for some heavy items, the amplitude of the spreader will increase, which will affect its internal structure. After long-term use, the noise will increase. Therefore, the requirements for high elasticity and large bearing capacity of the spreader are even more significant. Contents of the invention [0003] The object of the present invention is an elastic sling to solve the existing technical problems. [0004] In order to achieve the above object, the present invention provides the following technical solutions: an elastic sling, including lifting lugs, the lifting lugs are fixed on the fixing part through nuts, the fixing part is connected with a shock absorbing spring device, and a reinforcing rod is inserted in the shock absorbing spring device...
