In order to make machinery and equipment in a good state of safety, to ensure that the environmental impact of machinery and equipment to meet the standards, long service life, should be implemented in machinery and equipment, single-level or multi-level regular maintenance: regular maintenance to implement the principle of prevention. Specific provisions are as follows: 1. The periodic maintenance cycle of the equipment, operational projects, technical specifications, must follow the wear and tear of the various assemblies and parts of the equipment, combined with the use of the conditions, with reference to the requirements of the instructions for the implementation of the 2. Periodic maintenance is generally divided into routine maintenance and graded maintenance: graded maintenance for the second level of maintenance to clean, lubricate, fasten, adjust, and anticorrosion as the main content. 3. Routine maintenance is carried out by the machine The routine maintenance is carried out by the machine operator or equipment user in the on and off duty or handover time, focusing on cleaning, lubrication, inspection, and record keeping. 4. The first level of maintenance is carried out by the machine operator or crew, mainly centered on lubrication, fastening, by checking and fastening the external fasteners, and according to the lubrication charts for grease, lubricant, or replacement of the cartridge, etc. 5. The second level of maintenance is carried out by the mechanical supervisor in collaboration with the machine operator, Mechanic and other personnel to perform, mainly to tighten, adjust the center, in addition to the implementation of the first level of maintenance operations, should also check the electrical equipment, operating systems, transmission, braking, speed and walking mechanism of the working device, as well as tighten all the fasteners. 6. Maintenance at all levels should be to ensure that the systematic and complete, must be carried out in accordance with the provisions of the provisions of the requirements of the manuals or instructions on schedule, there should be no deviation from the 7. Project Department of the machine Supervisor should supervise the operator every month to carry out a level of maintenance, and keep the corresponding records, organize and summarize for inspection. 8. mechanical equipment repair, according to the scope of operation can be distinguished as follows: (1) minor repair: minor repair is maintenance repair, mainly to solve the equipment in the use of the process of malfunctioning and local damage, maintenance of normal operation of the equipment should be as far as possible according to the function of combining the maintenance and keep a good record of the maintenance. (2) project repair: based on the state of the inspection, the wear and tear of equipment close to the repair limit before the assembly, planned preventive, restorative repairs to extend the cycle of overhaul. (3) Medium repair: large equipment must be inspected and repaired before each transfer, replacing worn parts and components, disassembling and inspecting dissenting assembly parts, organizing the electrical control part, and replacing damaged wiring. 9. Reduce the pollution caused by noise, vibration, and glare to the environment of construction machinery in the process of construction by regular maintenance, and clean up the waste oil and waste operators in time in the maintenance process. Recycling, to ensure that its impact on the environment to meet the standards.
