What should be paid attention to in the use and maintenance of cranes?

Time: 2018-12-04 13:36

1. the crane must record its identity before leaving the factory. Safety inspection and maintenance before installation of equipment: check the integrity of the main parts of the equipment, check the visible defects of the main steel structures and connectors and their pins, bolts, check the corrosion conditions on the equipment surface, form records, and issue installation opinions.

2. cranes are specially maintained. After the equipment is delivered, the daily maintenance shall be responsible for the driver or the full-time staff of the equipment operator. The installation and maintenance unit shall have the obligation to supervise and inspect the daily maintenance contents. The main contents of daily maintenance are summarized as "cross work method": cleaning, fastening, lubrication, adjustment, anticorrosion. Every day before class and at the end of the class 10~30 minutes, check whether the parts and parts of the equipment are normal, lubricate according to the regulations, pay attention to the sound of the machine running, do the cleaning work and shift work so as to achieve the purpose of clean appearance and normal operation of the equipment. Daily maintenance records and handover records must be made into fixed forms, and be used as file management.

3. cranes should conduct regular physical examinations. Periodic inspection and maintenance in the process of equipment use: to maintain and repair mechanical equipment in a specified time, and to carry out cleaning, lubrication, adjustment, disassembly and maintenance as the central content. It is usually done by maintenance personnel and operators. After the crane is released, there is generally a 60 hour running in period (some are called the running in period), which is stipulated by the manufacturing plant according to the technical characteristics of the crane at its initial stage. The running in period is an important link to ensure the normal operation of the crane, reduce the failure rate and extend its service life. However, some users are not aware of the special technical requirements of the new machine due to the lack of common sense of crane or because of tight schedule or quick return. Some users even think that, in any case, the manufacturer has a repair period, the machine is broken, and the manufacturer is responsible for the maintenance, so the machine will be overloaded for a long time in the running in period, resulting in frequent early failure of the machine. This not only affects the normal use of the machine, shortens the life of the machine, but also damages the machine and affects the progress of the project. Therefore, attention should be paid to the operation and maintenance of the running in period of cranes.
