Hydraulic lifting principle of rear-turning dump semi-trailer

Dump semi-trailers are a necessity in important transportation industries such as the construction industry, real estate industry, machinery manufacturing industry, and home appliance industry, and occupy an extremely important position in the transportation economy. So what is the hydraulic lifting principle of a rear-turning dump semi-trailer?

Rear tipping dump semi-trailers are suitable for transporting bulk granular cargo such as coal, ore, and building materials, and can effectively improve loading, unloading, and transportation efficiency. The entire vehicle is optimized and designed using computer-aided design software. It is scientifically designed and reasonably loaded, effectively reducing the weight of the product under the same load. The frame is reasonably designed and manufactured with good craftsmanship. The box body is made of high-strength cold-rolled corrugated steel plate, without a skeleton structure. The box body has various height options and a large loading space. Multi-cylinder lifting, equipped with self-rescue cylinder, has the characteristics of multiple pulls and heavy loads.

Dump semi-trailers can be divided into two categories according to their uses: One type is heavy-duty and super-heavy dump trailers for off-road transportation, which are mainly responsible for transportation tasks such as large-scale mines and projects, and are usually used in conjunction with excavators. The other type of light, medium and large ordinary dump trailers used for road transportation are mainly responsible for the transportation of loose goods such as sand, soil, coal and so on, and are usually used in conjunction with loaders.

The principle of hydraulic lifting of a rear-turning dump semi-trailer is as follows: operating the power take-off device of the main vehicle gearbox to drive the hydraulic pump. The hydraulic pump inhales the hydraulic oil in the hydraulic tank through the low-pressure inlet pipe and generates high-pressure oil for output. The gear pump outputs The high-pressure oil enters the lift valve through the high-pressure oil pipe. The lift valve, under the control of the air control valve, delivers the high-pressure oil to the oil cylinder or drains it into the hydraulic oil tank to realize the lifting, stopping and lowering functions of the hydraulic cylinder.
