The detachable detachable trailer is widely used and is a common type of lowbed semi trailer. It is mostly suitable for the transportation of mechanical equipment, large objects, construction vehicles, stainless steel tanks, and special heavy goods.
The gooseneck part of the detachable gooseneck lowboy trailer manufactured by YUHANG is usually composed of four parts: traction system, force transmission system, alignment adjustment system and locking system. There are 4 units hydraulic devices installed on the gooseneck, one group is used for lifting the gooseneck, and the other group is used for the forward and backward movement of the gooseneck, which is convenient for disassembly.
Trailer use hydraulic cylinders to unload goosenecks, load cargo from the front or handle heavy equipment, which is a safer way to load and unload without damaging equipment or cargos.
The production department of YUHANG company carries out cutting, welding, strengthening, assembling and testing of steel materials according to the drawing details of the 4 axles 120 ton detachable gooseneck lowboy trailer confirmed by the customer. The specific production process is as follows:
1. Steel plate material cutting stage
According to the drawings made by the design department, use the plasma CNC cutting machine to cut out each required component, such as: beam web, reinforcement plate, standard small accessories, etc.
2. Submerged arc welding to fix the “I” beam
Fix the cut web and upper and lower flanges to the welding points and weld them with submerged arc welding.
3. Laser alignment
Cut out the beam web first, then cut out the U-shaped hole that the beam can pass through, and then fix the welded “I” beam in parallel. The result of calibrating the “I” beams is very important, if the parallel error of the two “I” beams is large, tire wear will appear.
4. Connect the side beams and weld the king pin
At this time, the main beam of the trailer is basically formed, and only the side beams are welded to form a frame structure. In addition, the king pin is welded to the position stipulated in the contract, and the welding process requires high requirements, otherwise the trailer will be skewed.
5. Welded frame and suspension
The size of the welded suspension must be strictly controlled to maintain a vertical state, otherwise it will also cause tire wear.
6. Connect the gooseneck
This process is to complete the welding of the gooseneck of the lowboy trailer and the chassis structure. The accuracy of welding is very important, because the angle deviation of the traction pin will affect the normal use of the semi trailer.
7. Lay the floor
Lay the steel plate with a thickness of 4mm on the load-bearing platform of the lowbed semi trailer. During the welding process, attention should be paid to the tightness of the weld with the frame structure. The bottom plate is made of patterned steel plate, which has strong friction and the highest stability for transporting goods.
8. Sanding and painting
Scrubbing and rust removal is the first step before painting, and the painting process is usually carried out in a well-ventilated work shed.
When the metal base and brake disc of detachable gooseneck lowboy trailer brake pads are in the state of grinding iron, bright cut iron will be seen near the edge of the tire rim. At this time, the brake pads that are close to the bottom line of life should be replaced in advance.
In order to reduce the load on the vehicle itself and the power system, you should choose a flat road to drive, avoid vibration, collision or emergency braking; avoid long-term continuous operation of the engine, which is easy to cause mechanical wear.
Grinding and polishing the surface of the lowboy semi-trailer, after removing the oxidized paint surface, the trailer can restore its luster, and form a layer of wax film on the outside of the paint to inhibit the oxidation of the paint by external harmful components. Sealing glaze can increase the strength of the paint, can avoid scratches and resist high temperature and ultraviolet rays.
