What is the Best Dump Semi trailer?

The best dump semi trailer is the 50 ton semi dump trailer, which is the most commonly used semi trailer. The transport load is relatively large, which can be used to transport more goods each time, and the 3-bridge 50 ton dump semi trailer conforms to the weight limit of most countries.

What is a dump semi trailer?

Dump semi trailer introduction:

The engine, chassis, and cab structure are the same as that of general trucks. The tipping box can be tilted backward or sideways. Rear dumpers are more common. Push the piston rod to tilt the box. A few two-way tips. The high-pressure oil enters the lifting hydraulic cylinder through the distribution valve and hydraulic hose.

And there is a safety protection plate at the front end of the cabin. The hydraulic tilting system is composed of a hydraulic pump, distribution valve, lifting hydraulic cylinder, controlling valve, and hydraulic hoses.

The engine drives the hydraulic pump through the transmission and the power take-off device. By controlling the movement of the piston rod through the controlling system, the tipping box can be stopped at any position. The tipping box uses its own gravity and hydraulic to return.

Semi dump trailer loading:

A dump semi trailer can load 50-120ton.

The main technical parameter of the tipping trailer is the payload and the loading volume. The new or overhauled semi dump trailer must be put into trial operation, ensuring stable lifting process.

The lubricant oil should be correctly selected according to the regulations and pay attention to the lubrication cycle, and maintain the lifting mechanism strictly on schedule. Overload is strictly prohibited. Tipping trailers can save unloading time and labor costs.

Dump semi trailer design:

Panda Mech tipping semi trailers are outstanding due to their excellent driving and tipping characteristics. The dump semi trailer drives safely on the road thanks to a low overall center of gravity and a stiff and torsion-resistant rigid frame structure.

  1. Best driving characteristics through a low center of gravity and innovative running gear
  2. Payload-optimized through low tare weight
  3. High working speeds through high-performance hydraulics
  4. Long service life through low-wear MEILLER tipper bodies
  5. Available in an angular or round tipper body shape

Dump semi trailer advantage:

  • 1. Robust and payload-optimized.
  • 2. Particularly suitable for short routes and frequent tipping.
  • 3. Designed for abrasive bulk material such as gravel, rocks, concrete rubble and aggregates.
  • 4. Optimized force transmission on the new chassis frame minimizes crack formation.
  • 5. Tailored blanks: reinforced tipper body floor in the rear third, as the abrasive wear is higher here.
  • 6. Optional wear plates for a higher lifetime.

Type of dump semi trailer

Rear dump semi trailer

The rear dump semi trailer is also called rear tipper trailer. It unloads goods through the rear door. They are commonly used to carry construction materials, industrial raw materials, and other materials.

The rear door of the dump semi trailer will be locked when loading goods. When the goods are unloaded, open the rear and lift the front part of the trailer. The goods will slide down by gravity. The rear dump truck trailers simplify the unloading process.

The bucket of the dump semi trailer is made of a thicker high-strength steel plate, which can bear the weight of hard materials. In this way, the stronger steel plate can prevent the trailer from being damaged.  

The rear dumper is suitable for cargo with a large rest angle. It is important to note that the length of the rear dumper cannot exceed 12m. Any tipper trailer that exceeds this length may be dangerous.

Side tipping trailer

The side tipper trailer is another type of dump trailer. This type of dump semi trailer allows you to unload cargo by the side door. And it also can be used to transport solid construction materials, such as sand and stones.

Hydraulic cylinder is installed on the other side to unload the dump semi trailer by the side door. This design is designed to allow side tipping. Sometimes the construction materials might be too big to pass through the back door, the offloading area might be small, and the side tipper has a smaller rest angle. Side tippers can help us load bigger and more goods.

Thick steel plates are also placed in appropriate locations to prevent possible trailer damage. Usually, the loading capacity of side tipper trailer is bigger than that of the semi dump trailer.

Type of tilt system

There are two types of tilt systems: Direct push type and link rod type

1. Direct push

This type is commonly used in the market. This simple mechanism can directly push the trailer up to unload cargo.

The tractor tilts the dump semi trailer’s floor to move the trailer backward.

The tow bar is usually hinged to a sliding mechanism, which is arranged under the floor and connected by a single link that leads to the wheels, which support a frame usually hinged to the rear of the floor.

Type of tilt system

When the sliding hinge is slid backward, the rod-frame-bed structure will change shape as the trailer tilts. You can lock the trailer in the desired position and still tilt the wheels backward so that the floor occupies a higher level than in the driving position.

The direct push mechanism can be located in the front, rear, or middle part.

2. Link rod type

This indirect and complex mechanism is designed to achieve a more effective push than the direct push type. This type still pushes the trailer up clockwise to unload the cargo.

In this case, the tow bar is hinged to a sliding mechanism arranged under the bottom plate,

It is connected by several links that lead to the wheels of the supporting frame, which is usually hinged to the rear of the floor, like most dump trucks.

Several moving rods are connected to transfer the movement to the trailer’s floor, causing it to tip over by the tractor, thereby moving the trailer backward.

As the trailer continues to tip, the connecting rods (frame and bed) arrangement is adjusted to be balanced in each position.

These linkages enhance lifting operations by reducing the force required. Ideally, this type of dump trailer can provide uniform strength on the truck body and ensure reduced thrust.

Most important, the universal mechanism improves the efficiency of the hydraulic cylinder. The linkage type assembly can face the front or the back.
