The use and maintenance of the break-in period should be given full attention

1. Before lifting the hoisting equipment out of the factory, it is necessary to make a record of the identity. Pre-installation safety inspection and maintenance: Check the integrity of the main components of the equipment, check the visible defects of the main steel structures and couplings, their pins and bolts, check the corrosion of equipment surfaces, form records, and issue installation opinions.

2. Lifting and lifting equipment shall be maintained by special personnel. After the equipment is delivered for use, the daily maintenance should be performed by the equipment operating driver or the full-time staff of the use unit. The installation and maintenance unit shall have the obligation to supervise and inspect the daily maintenance contents. The main contents of the daily maintenance section are summarized as the “cross-work method”: cleaning, fastening, lubrication, adjustment, and corrosion protection. Every day before class and at the end of class, 10 to 30 minutes, inspect all parts and parts of the equipment, check whether they are normal, lubricate according to the regulations, pay attention to whether the sound of mechanical operation is normal, and do a good job of cleaning work and handover work to achieve a neat appearance and normal operation of the equipment. For the purpose of this, routine maintenance records and hand-over records should be made into a fixed form and managed as a file.

3. Lifting equipment should regularly carry out professional medical examinations. Periodic inspection and maintenance during the use of the equipment: The mechanical equipment is maintained and repaired several times during the prescribed period of time, and the cleaning, lubrication, adjustment, disassembly, and maintenance are performed as the center. Generally completed by maintenance personnel and operators.

After the crane is shipped from the factory, it is generally specified that there is a run-in period of about 60 hours (sometimes referred to as the run-in period), which is defined by the manufacturing plant according to the technical characteristics of the initial use of the crane. 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 neglected the special technical requirements for the new run-in period due to the lack of cranes to use common sense or because of tight schedules or want to obtain benefits as soon as possible. Some users even think that, anyway, manufacturers have repair period, the machine is damaged by the manufacturer responsible for maintenance, so the machine is overloaded for a long time during the running-in period, resulting in frequent occurrence of early machine failures, which not only affects the normal use of the machine, The service life of the machine is shortened, and because the machine is damaged, the progress of the project is affected. Therefore, attention should be paid to the use and maintenance of the running-in period of the crane.
