Mechanical crane this large machinery needs regular inspection and maintenance, at any time to observe the abnormal situation of machinery, to ensure the safe operation of crane machinery. Daily inspection, weekly inspection, monthly inspection and annual inspection of the crane are usually carried out to ensure that the crane iswire ropeSafe and reliable. Let's learn about the specific content with Baxter.

1. daily inspection. The driver is responsible for the routine maintenance of the operation, which mainly includes cleaning and sanitation, lubrication of transmission parts, adjustment and fastening. Through the operation of the test device sensitive reliability, listen to the operation of abnormal sound.

2. weekly inspection. It is jointly carried out by the maintenance worker and the driver. In addition to the daily inspection items, the main contents are appearance inspection, inspection of the use status of hooks, pickup devices, wire ropes, etc., the sensitivity and reliability of brakes, clutches, and emergency alarm devices, and operation observation of transmission components for abnormal noise and overheating.

3. monthly inspection. The equipment safety management department shall organize the inspection and carry out the inspection together with relevant personnel of the user department. In addition to the contents of the weekly inspection, the state inspection of the power system, hoisting mechanism, rotary mechanism and operating mechanism of the hoisting machinery shall be mainly carried out, the worn, deformed, cracked and corroded parts shall be replaced, and the reliability of the feeding device, controller, overload protection and safety protection device shall be checked for the electrical control system. Check the failure symptoms caused by leakage, pressure, temperature, vibration, noise and other reasons of lifting machinery through test operation. Through observation, the structure, support and transmission parts of the crane are subjectively detected, the technical status of the whole crane is understood, and the fault source of the abnormal phenomenon is determined.

4. annual inspection. The unit shall guide and organize the equipment safety management department to take the lead and carry out the joint work with relevant departments. In addition to the monthly inspection items, the unit shall mainly carry out technical parameter inspection and reliability test for hoisting machinery, and pass 100 kt.Non-destructive testing of steel wire ropeInstrument, the lifting machinery, the working mechanism of the moving parts of the wear, metal structure of the weld, test detection, through the device and parts of the test, the lifting equipment operation technical status evaluation. Arrange overhaul, renovation and renewal plan.
