Maintenance Techniques For Easily Damaged Parts Of Warehouse Trailers During Daily Use

Warehouse rack trailers have become the mainstream model for overseas logistics trunk transportation due to their advantages of large loading space, flexible loading and unloading, and adaptability to the transportation of miscellaneous goods such as department stores and agricultural supplies. However, the warehouse rack structure is mostly hollow frame accessories, hinges, locks, and columns, which are numerous. Long term bumps and heavy loads can easily cause deformation, rusting, lagging, and damage. Many overseas fleets only maintain the tires and braking system in their daily lives, ignoring the maintenance of the warehouse rack exclusive structure, which shortens the service life of the trailer. Frequent maintenance and replacement of parts increase operating costs. Mastering the maintenance skills of high-frequency vulnerable parts of warehouse rack trailers can effectively reduce the failure rate and extend the service life of the entire vehicle, improving the efficiency of vehicle attendance. Firstly, the warehouse rack columns and frames are the most easily damaged parts. Vehicle loading and unloading goods are squeezed, bumpy driving, and goods displacement can cause column bending Regularly check the verticality of each column and the weld seam of the base. Any slight deformation should be corrected in a timely manner, and small cracks should be repaired and reinforced in a timely manner. When loading, avoid unilateral overloading, prevent local force distortion, and prevent the goods from being excessively hard and squeezing the warehouse grid frame. Secondly, the door handle of the opening and closing hinge of the warehouse grid is a high-frequency movable and vulnerable part. Long term opening and closing friction, rain and rust are prone to occur, and screws are prone to sticking and breaking. Loose opening and closing screws are easy to cause problems such as rusting and loosening of the hinge core. In rainy and dusty environments overseas, it is necessary to regularly clean the hinge gaps, dust and impurities, add lubricating grease to maintain smooth opening and closing. Check the wear of the lock buckle. Loosening screws should be tightened in a timely manner, and severely worn accessories should be replaced in a timely manner to avoid Easy to age and damage, long-distance travel High speed driving with wind, sand, friction, and rain exposure can accelerate the aging and cracking of tarpaulins, leading to water leakage and seepage problems. Loose pressure strip screws can cause tarpaulin displacement and deviation. Daily maintenance requires regular inspection of the surface of the tarpaulin for damage, holes, edges, and corners, and tightening of pressure strip screws one by one. Aging and worn tarpaulins should be repaired or replaced in a timely manner to avoid moisture damage to goods in rainy days. At the same time, the storage method of tarpaulins should be organized to reduce folding wear and extend their serviceLong term friction and collision between the bottom plate and side protective structure of the fourth carriage can easily cause damage to wooden boards, deformation of iron plates, cracking of welding seams, and accumulation of impurities in bulk goods, which can easily lead to rusting of the bottom plate. Daily cleaning of residual debris in the carriage is necessary to keep the bottom plate dry and tidy, and repair the damaged bottom plate in a timely manner. Correction and reinforcement of the protective strip on the side deformation of the damaged bottom plate to prevent further collision and accumulation of water and dust can lead to extensive rusting and perforation. The fifth carriage, the connecting base of the warehouse rack, is prone to fatigue and cracking. The overall frame of the warehouse rack trailer is heavy and the goods are dispersed under stress. Long term bumps can cause the fixed base of the warehouse rack to repeatedly pull and tear, resulting in welding and cracking. Many users only repair the frame without repairing the base, which leads to repeated damage The multi pole gap of the steel pipe cut is prone to water ingress and accumulation of dirt and grime. Long term rainwater immersion can cause internal corrosion of the pipe, resulting in thinning, perforation, and deformation of the pipe wall. After each car wash and rain exposure, it is necessary to maintain ventilation and dryness regularly. The weld seam of the pipe cut should be sprayed with anti rust paint from both the inside and outside. Many overseas drivers have the misconception of heavy transportation and light maintenance. If small faults in the warehouse rack are not treated for a long time, they will evolve into frame deformation and overall damage, greatly reducing the residual value of the trailer. Scientific targeted maintenance can effectively solve common faults of warehouse rack trailers, reduce maintenance frequency, extend the service life of the whole vehicle, and help overseas logistics.
