The best customized side dump semi-trailer is a new type of semi-trailer dump truck in China in recent years. Compared with the dump truck, the dump semi-trailer has a larger carrying capacity, lower transportation cost, and is more suitable for long-distance transportation. Compared with the regular semi-trailer, the self-unloading function is added, which reduces the labor intensity of workers and improves the loading and unloading efficiency. It has been widely recognized by market users. It has a very broad market and good development prospects.
Advantages and Characteristics of Best Customized Side Dump Semi Trailer
The best customized side dump semi-trailers are mostly used to transport bulk granular goods such as construction materials, ore and coal. The side dump semi-trailer not only has the advantages of stable transportation, but also greatly improves the transportation efficiency and loading and unloading efficiency. When unloading, the side of the carriage can be tilted and the door can be opened to start unloading, which can greatly shorten the unloading time and improve the efficiency of unloading. At the same time, the side dump semi-trailer has the advantage of multi-point distributed force and the force is well taken. At the same time, the lift cylinder travel of the side dump semi-trailer is not large during the unloading operation. Therefore, the two-way side dump unloading operation can be carried out, which has the advantages of convenience and flexibility. That’s why the side dump semi-trailer has been widely used in the transportation process.
How The Best Customized Side Dump Semi Trailer works
Most of best customized side dump semi trailers can perform two-way side dump operations. The structural design principle of the side dump semi-trailer is to provide multiple lifting structures at the bottom of the carriage. The two sides are turned over to carry out the cargo tilting operation. Adding the change of the flip pins connecting the two sides of the bottom of the box will accomplish the tipping and unloading operation of the box to both sides. This lifting structure has a very good working effect for the semi-trailer with a long carriage length. Most tipping semi-trailers use the same structure design for two-way tipping and unloading, but the structure design of the lifting cylinder is different due to different manufacturers. Most tipping semi-trailers are mainly composed of turning arm, turning pin, low-cost box body, cylinder installation and measurement, lifting cylinder, and vehicle cross frame.
Structure of Best Customized Side Dump Semi Trailer
The overall layout of the setup is mainly composed of a tractor, a semi-trailer chassis, a car body assembly, a braking system, a hydraulic system, and a pneumatic control system.
Chassis Design of Best Customized Side Dump Semi Trailer
The best customized side dump semi trailers has a load-bearing structure, which is mainly composed of a frame, landing gear, axles, suspensions, guardrails, tool boxes, etc. The semi-trailer can be easily connected to the saddle of the tractor by means of the traction pin. In addition to the gas and electrical connectors of a general semi-trailer, it is also equipped with a quick-change connector for the hydraulic system oil circuit. The front of the semi-trailer is equipped with lifting outriggers or landing gear. When the tractor is separated from the semi-trailer, the two front outriggers must be supported, and the outriggers are in a retracted state during driving.
Body Design of Best Customized Side Dump Semi Trailer
The carriage box of best customized side dump semi trailer is different from the general semi-trailer car body. The side cover is connected to the top of the car body, which can be turned up when unloading and makes it convenient for loading and unloading of goods. The whole car body is mainly connected with the frame through the hydraulic cylinder and the rotary bearing. Due to the large carrying capacity, the hydraulic cylinder and the connecting part of the rotary bearing should be firmly connected to avoid damage caused by excessive impact during operation. During the production process, the coaxiality of the rotary bearing should be strictly controlled to prevent the oil cylinder from interfering during lifting, which may cause difficulty in lifting or lifting. Sometimes, it may even cause distortion and deformation of the underframe of the carriage, which scrap the carriage box and total the trailer.
Brake System of Best Customized Side Dump Semi Trailer
The best customized side dump semi trailer adopts a double-pipe air brake system. A single-chamber brake air chamber is installed on the front axle of the trailer, and a double-chamber brake air chamber is installed on the rear two axles. The brake control is an emergency relay valve emergency system. When braking, it acts on the three axles through the brake air chamber. When parking, it acts on the rear two axles through the double-chamber brake air chamber.
Hydraulic System of Best Customized Side Dump Semi Trailer
The hydraulic system consists of four parts: hydraulic power source, hydraulic oil tank, carriage lift system, and shift cylinder working system. Its functions are lifting and lowering of the carriage.
Hydraulic Power Source of Best Customized Side Dump Semi Trailer
The power of the hydraulic source is taken from the tractor, and the power of the tractor is drawn out through the power take-off, which drives the gear pump to rotate and generate high-pressure oil. This is manipulated by the control valve in the cab and the high-pressure oil acts on the lifting cylinder to lift or lower the carriage.
Hydraulic Lift System of Best Customized Side Dump Semi Trailer
The direct push type lifting mechanism is adopted. Since the carriage of the side dump semi-trailer is longer and the total mass is larger when fully loaded, the direct push type is better. The lifting cylinders are arranged at multiple points along the longitudinal center of the semi-trailer. Large mass can be lifted with very high efficiency.
Shift Sylinder System of Best Customized Side Dump Semi Trailer
This mechanism is mainly used when the goods in the trailer has been dumped, the wheels are buried by stones nand sand and it is hard to break free. At this time, a shift cylinder should be used to move the entire semi-trailer chassis to one side to facilitate the removal of the whole vehicle. It should be noted that the stroke of the shift cylinder cannot be too small so as not to achieve the ideal effect of moving the car.
Pneumatic Control System of Best Customized Side Dump Semi Trailer
Mainly connect the air source control valve in the cab and the hydraulic control valve of the semi-trailer through the gas in the main air source of the tractor. The leakage gas of the position valve controls the inclination angle of the cabin.
