The 50t 3 axle end dump semi trailer has been favored by the market in recent years. In the process of visiting the market, we found that most of the users of end dump semi-trailers have been converted from ordinary fence semi trailer users. Most drivers lack the experience in lifting and unloading of dump trucks, and some inattentive or improper operations in the process of vehicle lifting have brought great potential safety hazards. We will share with you some of the lifting system and operation precautions of the rear dump semi-trailer.
With the implementation of GB1598-2016 and the weight limit standard and the changes in the domestic coal transportation environment, the 50t 3 axle end dump semi trailer has been favored by the market in recent years.

We will share with you some of the lifting system and operation precautions of the rear dump semi-trailer.
The end dump semi trailer train is mainly composed of a tractor and a semi-trailer, while the main vehicle (tractor) is connected by the saddle and the 50t 3 axle end dump semi trailer semi trailer to form a semi-trailer train. The hydraulic lifting system of the end dump self-unloading semi-trailer is mainly composed of a power take-off (gearbox), a hydraulic pump, a lift valve, an air control valve, a limit valve, a hydraulic cylinder, a hydraulic oil tank, and a high (low) pressure oil pipe.
The hydraulic lifting principle of the 50t 3 axle end dump semi trailer is as follows: the power take-off device of the main vehicle gearbox is operated to drive the hydraulic pump. The high-pressure oil enters the lift valve through the high-pressure oil pipe, while the lift valve transmits the high-pressure oil to the oil cylinder that drains it into the hydraulic oil tank under the control of the air control valve to make the lift, intermediate stop and lowering functions of the hydraulic oil cylinder.
The new 50t 3 axle end dump semi trailer should be lifted slowly during the running-in period. In principle, the engine speed should be controlled at about 1000 rpm, and it should not exceed 1500 rpm after the running-in period.
Due to the existence of iron filings and other impurities in the hydraulic system of the 50t 3 axle end dump semi trailer should be cleaned when the new trailer has been lifted about 300 times.
The high pressure oil pipe must be replaced every two years. If the hose is found to be leaking, damaged or partially bulged or cracked during routine maintenance, it should be replaced in time.
Check the hydraulic oil every week for discoloration and deterioration. If there is discoloration and deterioration, it should be replaced in time. The hydraulic oil should be changed according to the region and season. Generally, it is more appropriate to change the oil in April and October. When the oil is found to be insufficient, it should be replenished in time. The specific area and recommended oil are shown in the figure below;
The upper and lower brackets of the oil cylinder should be filled with grease in time. It is recommended that the oil cylinder be filled with grease once every 120 times or every 15 days. It needs to be filled with grease again before returning to use when it has not been used for a long period of time.
Check the oil return filter element and air filter element inside the hydraulic tank every half month for debris and clean if necessary. Replace the oil return filter element and air filter element of the hydraulic tank every six months.
