Abstract

The invention discloses a load testing device and a method of a container crane. The device comprises a lower lifting frame and an upper lifting frame symmetrically arranged left and right; the lower lifting frame includes two first cross beams and multiple first longitudinal beams; the first cross beams and the first longitudinal beams are perpendicularly intersected; double-lug bases are arranged in the intersecting positions of the first cross beams and the first longitudinal beams; the upper lifting frame includes two second cross beams and multiple second longitudinal beams; the second cross beams and the second longitudinal beams are perpendicularly intersected; multiple stand columns are arranged at the lower parts of the intersecting positions of the second cross beams and the second longitudinal beams; fixed holes are formed in the bottoms of the stand columns; pin shafts penetrate through the fixed holes and the double-lug bases to connect the upper and lower lifting frames; container upper angle parts are arranged at the upper parts of the intersecting positions of the second cross beams and the second longitudinal beams on the left and right two sides; lifting lugs are arranged at the upper parts of the intersecting positions of the second cross beams and the second longitudinal beam at the middle part; and multiple lifting lug holes are formed in the lifting lugs. The device solves the technical problems of single purpose, incapability of adjusting lifting point positions and inconvenience for loading and unloading loads in a traditional crane load testing device.

Description

technical field [0001] The invention relates to the field of hoisting auxiliary devices, in particular to a crane load test device and method. Background technique [0002] As a special operation equipment, cranes must be preloaded before use. They are allowed to be delivered only after passing the test and obtaining a certificate from the quality supervision department. The current general test method is: according to the requirements of the working conditions of the crane, design and manufacture loads with similar structures to simulate normal operating tasks. [0003] The difficulty with this test method is that: [0004] 1. There are various working conditions, and ordinary loading devices lack versatility, which is easy to cause waste; [0005] 2. There are many types of loads, and ordinary load-carrying devices lack adaptability, which makes it difficult to meet the experimental tasks; [0006] 3. During the test, the load needs to be increased to 1.25 times the rat...
