In the field of construction machinery, proper storage and maintenance is not only the key to maintaining the performance of the equipment but also an important guarantee to ensure that future work is carried out efficiently. Especially for those who may be idle for a long time for the construction machinery, how to implement a scientific and systematic long-term storage and maintenance strategy, has become the focus of attention inside and outside the industry. In this paper, we will discuss the maintenance points of long-term storage of construction machinery, for your equipment escort.
First, site selection and basic protection
First of all, construction machinery should be preferred to a dry, well-ventilated indoor environment for storage, in order to minimize the erosion of the natural environment on the equipment. If it must be parked outdoors, you need to carefully select the flat and well-drained ground, and pave with wooden planks to prevent the ground moisture on the bottom of the equipment caused by damage. In addition, should be parked on time with a cover cloth to cover the equipment, and further isolate the external environment.
Second, comprehensive overhaul and cleaning
Before long-term storage, it is crucial to carry out a comprehensive and detailed overhaul of construction machinery. This includes the repair of damaged parts, lubrication system inspection and maintenance, electrical system testing and adjustment, etc., to ensure that the equipment is in the best technical condition. At the same time, thoroughly clean the equipment inside and outside, to remove the accumulation of dust, oil and other impurities, to lay a good foundation for long-term storage.
Third, scientific planning and layout
Storage site planning should not be ignored. Ensure that the arrangement and layout of machinery are reasonable, to avoid mutual interference, to facilitate future access and maintenance. At the same time, taking into account the rapid response to emergencies, need to reserve enough space for rescue vehicles and personnel access.
Fourth, engine special maintenance
For the engine as a core component, long-term storage during maintenance is particularly important. First of all, the engine cooling water needs to be drained to prevent ice expansion and damage to the body. Secondly, replace the new oil to ensure that the oil is neutral and does not corrode the metal parts of the engine. The fuel tank should be filled with diesel fuel and add anticorrosion agents as appropriate to prevent fuel tank rust. In addition, it is recommended to start the engine once a month for short-distance driving to lubricate the parts and prevent rust.
Fifth, the battery professional management
Battery as a power source of construction machinery, its long-term storage and maintenance should not be ignored. The battery should be removed and placed in a dry, anti-freezing place, keep the surface clean and dry, and avoid contact with conductive objects. At the same time, follow the "first negative after the positive" principle of disassembly to prevent short-circuit. For lead-acid batteries, it is recommended to charge once a month to maintain the power level.
Sixth, anti-rust measures to strengthen
Rust prevention is an important part of the long-term storage and maintenance of construction machinery. Before storage, the outer surface of the equipment should be carefully examined rust-proof paint layer, for the peeling part can be used to repair the paint or the whole machine repainting way to repair. The exposed metal part of the working device, such as the screed of the paver, the bucket of the loader, etc., should be coated with butter and other rust inhibitors for protection.
To summarize, the long-term storage and maintenance of construction machinery is a systematic project, which needs to start from many aspects such as site selection, overhaul, planning, engine maintenance, battery management and rust prevention treatment. Through scientific and systematic maintenance measures, we can ensure that the equipment can still maintain good performance after a long period of idleness, and lay a solid foundation for future efficient work.
