U-shaped Dump Trailer is suitable for the transportation of bulk and scattered goods such as coal, ores, and construction materials. U-shaped Dump Trailer 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.

Precautions When Operating

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.
