Introduction to the maintenance plan of the crane First: Before lifting the lifting equipment, it is necessary to make an identity record. Safety inspection and maintenance before installation: Check the performance of the main equipment of the equipment, check the visible defects of the main steel structure and coupling parts and their pins and bolts, check the corrosion protection of the surface of the equipment, form a record, and issue installation opinions. Secondly: the lifting and hoisting equipment is maintained and maintained by a special person.
After the equipment is delivered and used, the daily maintenance of the crane shall be the responsibility of the operator of the equipment operation or the full-time staff of the unit. The installation maintenance unit shall be responsible for the supervision and inspection of the daily maintenance contents.
The main content of the daily maintenance of the crane is summarized as the "cross operation method": cleaning, fastening, lubrication, adjustment, anti-corrosion. Every day before the shift, 10 to 30 minutes at the end of the class, check whether all parts and parts of the equipment are normal, refuel according to the regulations, pay attention to whether the mechanical operation sound is normal, do the cleaning work and handover work, in order to achieve a neat appearance and normal operation. For the purpose, the crane daily maintenance records and handover records are to be made into fixed forms and managed as files.
Again: lifting and hoisting equipment should be regularly carried out for professional medical examinations. Regular inspection and maintenance during the use of the equipment: several maintenance and repairs of the mechanical equipment during the specified time, with cleaning, lubrication, adjustment, disassembly and overhaul as the central content. It is usually done by maintenance personnel and operators. After the crane leaves the factory, it is generally stipulated that there is a running-in period of about 60 hours (some called the running-in period), which is stipulated by the manufacturing plant according to the technical characteristics of the initial use of the crane. The running-in period is an important part of ensuring the normal operation of the crane, reducing the failure rate and prolonging its service life. However, some users lack the common sense of crane use or because of the tight schedule, or want to get the benefits as soon as possible, while ignoring the special technical requirements of the new machine running-in period. Some users even think that anyway, manufacturers have a repair period, the machine is broken and the manufacturer is responsible for maintenance, so the machine is overloaded for a long time during the running-in period, resulting in frequent machine failures, which not only affects the normal use of the machine. It shortens the life of the machine and also affects the progress of the machine because of machine damage. Therefore, the use and maintenance of the crane's running-in period should be given full attention.
