1. What is a dump trailer?

1.1 Introduction of Dump Trailer

Dump trailers are one of the most suitable semi-trailers of all models. Besides "tipper trailer", it can also be called "dump trailer" or "end dump trailer". It is mainly used in the construction, agriculture and recycling industries. Due to the special structure and fast unloading speed, it is often used for handling various large-sized goods.

The essence of the dump trailer lies in the hydraulic cylinder. When unloading bulky goods, the boom lifts up, making the hopper tilt 45 degrees, so that the goods slide down. Usually, dump trailers can load 30-70 tons of cargo and can be emptied within half an hour.

1.1 Important Parts of Dump Trailer

As the soul of the dump trailer, the hydraulic cylinder plays a pivotal role in the unloading process. Panda uses HYVA cylinders for quality and efficiency. It is easy to maintain and fully ISO 9001 compliant, providing a longer service life.

Due to the unloading method, the steel of the dump truck must be specially made. Panda uses Hardox steel with high wear resistance. What's more, covered with polyurethane paint, the steel becomes rust-resistant. So no matter how rough the goods are, it can provide more than 7 years of service.

In order to support the heavy hopper and absorb the vibration of the road, the chassis of the panda dump trailer adopts a thickened main beam and a row of beams, which lays a solid foundation for the excellent quality.

2. Types of dump trailers

2.1 Rear dump truck

As you can see, the rear dump truck or rear dump trailer is unloading cargo through the rear door of the trailer. This method of unloading has a narrower exit but provides protection on the side. As such, it is often used to unload various building materials such as rocks, sand, stones, and even coal.

When working, the hydraulic cylinder lifts the front part of the dump truck with force, and the goods slide down spontaneously by gravity. According to the information we mentioned above, you don't need to worry about scratches when the dump truck is made of high-strength Hardox steel. This method of unloading is simpler and can greatly save your labor costs (no need to hire someone to operate the unloading).

It is worth noting that the rear dump truck is a perfect semi-loaded cargo with a large resting angle. The rear dump truck is suitable for goods with a large static angle, so the maximum length is 12m.

2.2 Rollover

Side dump trucks are also common in the market, similar to rear dump trucks. It can also transport building materials between factories, but a rollover allows you to unload cargo through the side doors.

Since the dump truck unloads through the side door, the hydraulic cylinder is installed on the other side. The reasons for this design are that sometimes the building material may be too large to pass through the rear door, the unloading area may be small, and the rollover vehicle has a small stationary angle. So with side doors, we can load bigger and more cargo in one way. This is an unparalleled feature of this model.

In addition, the steel plate is of the Hardox high-strength type, which prevents possible damage during discharge.
