Description

Technical Field

[0001] The utility model belongs to the technical field of lifting equipment, and in particular relates to a steel wire rope detection device for a bridge crane. Background Art

[0002] Crane ropes need to be quality inspected before they can be installed, and the force range of the ropes can be understood through testing.

[0003] The existing detection device can only pull the steel rope, but in fact the detection of the steel rope cannot be judged by whether the steel rope breaks after being pulled. It is also necessary to observe whether there are cracks on the surface of the steel rope after being stressed. For this step, on the existing equipment, the steel rope needs to be removed from the detection equipment, observed under a microscope separately, and then installed on the detection equipment to increase the pulling force of the test until the maximum tension that the steel rope can withstand is understood. In this way, the steel rope is inevitably installed and disassembled repeatedly, which is time-consuming and laborious. Summary of the invention
