Before hoisting operation, in addition to determining the good working steps, construction plans and safety measures in advance, the test crane link can not be omitted.
Generally speaking, in the process of test crane can help to find lifting machinery, hoisting belt, sling state can withstand the hoisting operation, but also the entire hoisting process to drill a bit, improve operational safety. All kinds of lifting machinery, hoisting belt, sling tools should be used before the test crane. Test hanging money, but also should carry out a comprehensive inspection of lifting machinery, confirmed good, can be carried out. The test crane comprises a static load and a dynamic load. The weight of the static load test crane should be 1.25 times times the calibration of the lifting weight, lifting the midday 0.1-0.3m high, staying for 10 minutes, the inspection of each part.
The weight of the dynamic load test crane is 1.1 times times the calibration of the lifting weight, after the appropriate height, do the stripping rod rotation and other actions, and then check whether the lifting machinery parts are good, after confirmation of the qualified, can be used. Do a good job of the above requirements at the same time, Oriental power God hope that the vast number of users to do a good job in the selection of operators, all operators should be proficient in lifting operation of the general knowledge, the operation of the object's operating technology and safety regulations in mind, only in order to ensure the realization of safe and efficient hoisting.
