Description

Technical Field

[0001] The utility model belongs to the technical field of gate hoist testing and relates to a gate hoist load-bearing testing device. Background Art

[0002] The gate hoist is used in various large-scale water supply and drainage, water conservancy and hydropower projects. It is used to control the lifting and lowering of various large and medium-sized cast iron gates and steel gates to achieve the purpose of opening and closing. The gate hoist consists of a motor, a gate hoist, a frame, a protective cover, etc. After the gate hoist is produced, the load-bearing capacity of the gate hoist needs to be tested.

[0003] The existing load-bearing test of the gate hoist usually involves lifting and lowering a number of metal plates or other counterweights through a sling, thereby testing the load-bearing capacity of the gate hoist. However, when performing the counterweight test on the existing metal plates or other counterweights, the metal plates or other counterweights need to be weighed in advance. The steps of adding metal plates or other counterweights during the load test are cumbersome, which reduces the efficiency of the load test. Therefore, we propose a gate hoist load-bearing test device that is convenient for counterweighting. Utility Model Content
