Proper storage of dump trailers begins with ensuring the site meets specific standards. Vehicles should be parked on level, solid, and well-drained ground; parking for extended periods in soft, muddy, or waterlogged areas must be avoided to prevent the wheels from sinking or the chassis from corroding due to moisture. Whenever possible, indoor or covered storage is preferable to minimize the impact of rain, UV radiation, and wind-blown sand or dust on the vehicle's structure and hydraulic systems.
Managing the vehicle's parked state requires particular attention to the safety of the hydraulic lifting system. Before storage, the trailer bed must be fully lowered to its horizontal position; parking with a load or in a partially raised position for extended periods is strictly prohibited, as prolonged pressure on the hydraulic system can damage seals or cause cylinder leaks. Additionally, the parking brake must be fully engaged, and wheel chocks should be used if necessary to prevent accidental rolling.
Long-term storage also necessitates regular inspection and maintenance. The vehicle should be started or moved periodically to prevent tire deformation and bearing lubrication failure; checks should also be performed for hydraulic fluid leaks, brake system malfunctions, and electrical system deterioration. For extended storage periods (exceeding one month), anti-rust measures-such as applying protective oil or anti-rust paint to exposed metal parts-should be taken to extend the vehicle's service life and ensure safety when it is put back into operation.
