Install appropriate lining plates: polyethylene liners work for light materials, rubber liners for sharp or heavy cargo, and steel liners for extremely hard loads. Frequently inspect the liners for damage. After every haul, wash the cargo body with a high-pressure washer and dry it thoroughly to prevent rust; gently scrape off any hard material buildup.
Tires should not be overlooked either. Maintain proper tire pressure, rotate tires regularly, and replace them promptly once worn. Avoid sharp debris that could puncture the tires. When unloading, park on level ground, lift the cargo body slowly, operate strictly within the recommended hydraulic pressure range, and clear the unloading zone to prevent damage caused by bouncing loads.
Regular maintenance and choosing the right trailer are also critical. Develop a periodic maintenance schedule: replace hydraulic oil and filters, lubricate suspension components, inspect and replace brake pads as needed, check the cargo body and frame for rust or cracks, and tighten all loose bolts.
Be sure to select trailers specially engineered for aggregate transportation, featuring robust frames and tandem or tri-axle designs to evenly distribute weight. Using an unsuitable trailer will drastically shorten its service life.
Following these procedures can extend the service life of dump trailers and cut costs in the long run.
Dump trailers are essential equipment for hauling heavy abrasive materials such as gravel and crushed stone. Frequent loading, unloading and transit of these cargoes accelerate trailer wear, driving up maintenance costs and downtime. To extend the trailer's service life, inspections must be carried out before and after every trip: Prior to transport, check tires, brakes, suspension system, hydraulic system and cargo bed liners for damage. Upon finishing delivery, thoroughly clean the cargo bed to remove all leftover materials, then reinspect for newly emerged defects. Additionally, exercise caution during loading: Do not stack materials over the height limit, distribute weight evenly, and separate sharp aggregates whenever possible to protect the cargo bed.
