Dump semi-trailer is suitable for the transportation of bulk and scattered goods such as coal, ores, and construction materials. Dump semi-trailers can be divided into two categories based on their purposes. The first one is heavy-duty and super heavy-duty dump trailers for off-highway transportation, which mainly undertake transportation tasks such as large-scale mines and engineering sites, and are usually used in conjunction with excavators. The other type of light and medium-sized ordinary dump trailers are for longer distance road transportation. These trailers are mainly responsible for the transportation of loose goods such as sand, soil, and coal, and are usually used in conjunction with loaders.

The hydraulic cylinder of the dump trailer is a lifting cylinder. It is strictly forbidden to use the cylinder as a stable support for the entire trailer body.
Under the lifting state, the time of the cylinder in the air should not exceed 2 hours. That time should be shortened to no more than 30 minutes when the working condition is humid. Otherwise, the cylinder will be oxidized and corroded.
It is strictly forbidden to disassemble and adjust the relief valve on the lifting net. Otherwise, the hydraulic system will lose its safety protection function and can it can be very dangerous.
When loading the vehicle, make sure that the cargo weight is evenly distributed on the trailer. If the cargo is loaded too tightly, it will cause the hydraulic system to overload. If the cargo is loaded too far behind, the possibility of the trailer overturning will increase significantly. If the cargo weight is concentrated on either the left or right side of the trailer, the oil cylinder could be seriously stressed and damaged, which could also result rollover.
When unloading, make sure that the surface where the trailer is located is firm and flat so that the trailer is kept level, and the tractor truck and the trailer are in a straight line.
During the lifting operation, the operator cannot leave the operating position. It is strictly forbidden for anyone to stand or walk near the work area.
During the lifting operation, the operator must pay close attention to any wind. Due to the fact that dump trailer is very long, the force of lateral wind on the surface of the trailer body may cause the trailer to roll over.
Try not to touch the rear door with the cargo carried unless it can be guaranteed that it will not jam the main rear door. Be sure to open the rear door lock device before lifting and unloading. Otherwise, the cargo will cramp to the rear of the trailer when unloading, which will cause overturn.
When unloading at temperatures below 0°C, be sure to pay attention to whether the cargo is frozen, or the vehicle will roll over due to imbalance between the left and right.
Do not move the vehicle when the carriage is lifted. Do not apply any sudden braking to unload sticky goods. Otherwise, it will cause the vehicle to roll over or damage the oil cylinder.
If the lift angle of the trailer body reaches about 25 degrees, at which point it has lifted halfway, and the cargo in the car has not been unloaded, stop lifting and check for the cause of sticking.
If you feel that a rollover may occur when lifting, stop lifting and slowly lower the carriage.
Wait for about 30 seconds after the carriage has been dropped level. Be sure to put the air control handle in the stop position, and do not start the vehicle in the lowered position. This is to avoid the hydraulic oil in the hydraulic cylinder returning to the hydraulic oil tank, which will cause cylinder cavitation and fuel injection problems in the fuel tank.
When the trailer needs to be lifted during repair or maintenance, please make sure that the vehicle is safely supported. Working under the unsupported vehicle will endanger lives.
