The strength of the End Dump Trailer production base has created quality, and the strong strength guarantee has created the excellent quality of high-tonnage semi-trailers and consolidated its position in the eyes of consumers.

End Dump Trailer refers to a vehicle that unloads cargo by hydraulic or mechanical lifting, also known as a dump truck. It is composed of automobile chassis, hydraulic lifting mechanism, cargo compartment and power take-off device. It is very convenient for our transportation. As such a good transportation tool, End Dump Trailer must have its scope of application. In civil engineering, it is often used with excavators, loaders, belt conveyors and other construction machinery. The joint operation constitutes a loading, transportation and unloading production line to carry out the loading, unloading and transportation of earth, sand, and bulk materials.

Where is the crack of End dump trailer?

1. Cracking of the weld between the flip beam and the web

Card friends all know that during the driving of the Tri Axle End dump trailer, the torque of the car is very large, especially the lower wing. The twisting force of the lower wing plate acts on the turning beam through the turning beam diagonal bracing. The welding place between the web and the turning beam is very stressful, and the welding seam at the turning beam and the web is prone to cracking.

2. Suspension ribs cracked

Generally speaking, the dangerous section of the component appears in the variable section. The arc angle of the variable section of the suspension rib of the dump truck is small, and the stress is too concentrated. At the same time, due to the nearby weight reduction hole, the rib of the plate is greatly reduced. The strength at the section of the plate causes a fracture at that section. When the End dump trailer passes through complex road conditions, twisting occurs here and cracks appear on the web.

3. Suspension diagonal brace and suspension brace cracking

The suspension of the frame is the place where the torsion is relatively large, especially when the frame is rapidly turning, the lateral force received by the tires will act on the frame through the axle, leaf spring, suspension, etc. And because there is no connecting tube at the suspension of the car, we can regard the vertical distance from the contact point of the tire to the ground to the frame as a moment arm. It can be seen that the frame has a large moment, especially at the lower wing. Torsion occurs, causing cracks in the inner and outer support plates.

4. Suspension brace cracking

Some 40 Ton dump semi trailers have no reinforcement on the upper web of the suspension. The suspension brace is welded to the connecting pipe. When the vehicle is running, especially when passing a bumpy and curved road section, the suspension is twisted a lot. The stress of the diagonal bracing plate is too concentrated at avoiding the wing plate, which causes the suspension to be diagonally braced.

5. Sub-frame turning beam reinforcement diagonal brace cracking

There are two main reasons for the cracking of the diagonal bracing reinforcement of the sub-frame flip beam. The first sub-frame longitudinal beam and the flip cross beam are cross-butted, and the strength is weak. When the vehicle is turned over and unloaded, the flip cross beam becomes deformed; second, since When unloading, the front and rear cylinders are not synchronized, and the sub-frame is twisted, causing cracks.

Where is the root cause of the end dump trailer cracking?

1. The design considerations of trailer companies are not comprehensive enough, and there are stereotyped thinking

The priority of the End dump trailer is of course the load-bearing capacity of the trailer. However, in addition to the load-bearing capacity of the trailer, car companies must also seriously consider how to ensure the safe performance of the dumping function of the dump truck, such as the selection of oil cylinders, and the force of the sub-frame and suspension under different conditions during lifting. Must be considered.

2. The welding process of some trailer companies needs to be improved

End dumper trailer is currently still in the development stage. The products on the market are relatively mixed, and the welding process and quality levels are not uniform. In order to reduce costs, some trailer companies occupy the market at low prices, choose non-standard steel, cheap and low-quality accessories, and do not pay attention to the welding process, which easily leads to product quality problems. If the welding process is not in place, the most typical manifestation is that the weld cracks under stress.

How does End dump trailer prevent cracking?

1. Add a reinforced plate to the inner side of the End dump trailer web to solve the problem of weld cracking between the flip beam and the web. 3 Axle End dump trailer adds black-type reinforcing plate to the inner side of the web, which can effectively strengthen the strength of the flipped square tube and the web here.

The strength of this position is strengthened. The welding place of the web and the flip beam bears the torsion of the lower wing plate. When powered, it will be safer and the risk of cracking will be greatly reduced.

2. The inner and outer ribs of the suspension are supported, and the upper and lower ribs are welded to the wing plates to smooth out the cracks of the suspension ribs. The suspension of 3 axle End dump trailer is supported by ribs inside and outside, and the top and bottom are welded to the wings.

The ribs have a long strip shape with holes on the side. This process can not only reduce weight but also improve welding efficiency. The design is scientific and easy to operate, which better solves the problem of suspension ribs cracking.

3. Weld the suspension diagonal brace plate and the suspension connecting pipe together to ensure the safety of the suspension diagonal brace. Welding the suspension diagonal brace of the dump truck and the suspension connecting pipe together will form a frame structure.

Details of 40 Ton End Dump Semi Trailer

The upper web of the suspension is supported by ribs. The design of the 40 cbm End dump trailer can greatly increase the suspension. The rigidity and stability of the location are conducive to ensuring the safety of suspension diagonal braces and large braces.

4. Suspension diagonal bracing plate is of straight slab style, and the upper web is supported by ribs to resist cracking of diagonal brace. The suspension diagonal support plate is designed as a straight plate style, and the upper web plate is supported by ribs, which can well increase the rigidity of the suspension and the adaptability to the road surface.

During the driving process of Tri Axle End dump trailer, it is inevitable to go through bumpy bends and curved roads to generate force to twist the suspension. This design can effectively avoid excessive stress at the wing panels, which is very useful for preventing suspension cracks. Good results.

5. Add a triangle plate to evenly distribute the cylinders to deal with the cracking of the diagonal brace reinforcement of the flip beam of the sub-frame. Aiming at the problem of cracking of the diagonal bracing reinforcement of the sub-frame flip beam, first of all, the End dump trailer added a triangular plate at the cross butt joint. This process has good stability, lightweight and strong stress effect.

Secondly, for the distribution of the entire vehicle's cylinders, the Grizzly 40t dump semi trailer is designed as evenly as possible, which can reduce the occurrence of cylinder out-of-synchronization. These two targeted measures enable End dump trailer to effectively cope with the cracking problem of the diagonal brace reinforced by the flip beam of the subframe.
