Mingcheng BYD anti-corrosion forklift maintenance, special model maintenance item reference

The maintenance logic of BYD anti-corrosion forklifts used in the Mingcheng area under special working conditions such as chemical storage, aquatic product processing, and coastal high salt spray is obviously different from that of ordinary electric forklifts. It cannot directly apply the general maintenance standards of conventional models. It is necessary to combine the design characteristics of the anti-corrosion structure and formulate a suitable maintenance plan in order to fully retain the anti-corrosion protection performance of the whole vehicle and prolong the service life of the equipment.

The first is the daily basic inspection maintenance project, which requires the operation and maintenance personnel to complete the operation according to the specifications before and after each operation. First, check the integrity of the exposed anti-corrosion coating of the whole vehicle, focusing on the parts of the fork arm, the body chassis, and the operating handle base that frequently experience friction and collision, and confirm whether the coating falls off or bumps to the bottom. If small area damage is found, it should be recoated in a timely manner to avoid corrosive media from invading the metal substrate along the damaged part and causing deep corrosion. The second is to do a good job of cleaning the attachments on the tires and rims. After each operation, the corrosive waste liquid and salt crystals attached to the rim should be cleaned in time to avoid long-term adhesion to accelerate the corrosion and cracking of the rim. At the same time, clean up the hard impurities left in the gaps of the tire pattern to avoid sharp debris scratching the outer layer of the rubber and reducing the overall anti-corrosion sealing performance. The third is to check the status of the sealing strip of the battery compartment. The battery compartment of the anti-corrosion model has made an exclusive sealing protective structure. Each inspection should confirm that the rubber strip is not cracked or displaced. After the warehouse door is closed, the gap is uniform to prevent corrosive water vapor from infiltrating and damaging the internal power system.

The second is the monthly in-depth maintenance project, which requires the equipment to carry out a special project maintenance every 100 hours of operation or 30 days of the natural month. First, the movable hinge parts of the whole vehicle, such as the gantry hinge, steering joint, and brake pin, after cleaning up the residual corrosive adhesives on the surface, apply suitable anti-corrosive grease. Conventional grease under ordinary working conditions cannot be used to avoid the grease from rapidly decomposing in case of corrosive media, resulting in the problem of stagnation and poor rotation of the hinge parts. Second, check the state of the sealing waterproof rubber ring of the electrical connector, comb the exposed line joints of the whole vehicle one by one, confirm that there is no oxidation and greening, aging and deformation of the rubber ring, and re-tighten the loose joints. At the same time, apply special anti-corrosion protective agent on the surface of the connector to reduce the probability of electrochemical corrosion. Third, do a comprehensive investigation of the pipeline interface of the hydraulic system, check whether there is any oil leakage, corrosion and aging of the interface sealing ring, and replace the seals that have shown signs of embrittlement in time to avoid the leakage of hydraulic oil affecting the safety of the operation.

Finally, the quarterly special project maintenance project, every 300 hours of operation or every 90 days to carry out a comprehensive investigation. First lift the whole vehicle to do a full range of inspection of the chassis, check whether the anti-corrosion protective layer on the inside of the chassis has a large area of bulging and falling off, and focus on rust removal and recoating on the parts that have been in contact with the ground moisture medium for a long time to ensure the integrity of the overall anti-corrosion structure. Secondly, do a comprehensive cleaning of the heat dissipation parts of the braking system and the walking motor, and clean up all the corrosive dust accumulated in the heat dissipation gap to avoid dust accumulation resulting in a decrease in heat dissipation efficiency, and at the same time avoid dust from sticking to the motor shell for a long time. During daily operation and maintenance, the maintenance interval can also be adjusted appropriately according to the actual corrosion level of the operation scene to further ensure the stability of equipment operation.
