1. What is a tipper semi trailer?

1.1 Introduction of a tipper semi trailer

Tipper semi trailer is one of the most applicable semi trailers. Besides “tipper semi trailer”, it can also be called “dump trailer” or “end dump trailer”. It is mainly used for the construction, agriculture, and recycling industries. Due to the special structure, it can unload cargo rapidly, therefore it’s often applied to carrying various kinds of bulky goods.

The key point of tipper semi trailer is the hydraulic cylinder. When unloading the bulky goods, the lifting arm goes up and tilts the hopper by 45 degrees to make the goods slide down. Usually, the tipper trailer can carry 30-70 tons and these can be emptied within half an hour.

1.1 Important Parts of a tipper semi trailer

As the soul of the tipper semi trailer, the hydraulic cylinder plays a significant role in the unloading process. Panda uses HYVA cylinders to guarantee quality and efficiency. It is easy to maintain and ISO 9001 compliant fully, which can provide longer service life. 

Due to the unloading way, the tipper’s steel must be special-made. Panda uses Hardox steel of high wearing resistance. What’s more, covered with polyurethane paint, the steel becomes anti-rust. So no matter how rough the cargo is, it can provide services over 7 years.

To support the heavy hopper and absorb the oscillation while on the road, the tipper truck trailer’s bed of Panda is made of a thickened main beam and a row of cross beams, which set a firm foundation for superior quality.


2. Types of Tipper semi Trailers

2.1 Rear Tipper

As you see, the rear tipper truck or rear tipper semi trailer, unloads the goods through the rear door of the trailer. This unloading way is with narrow outlet but it can provide protection. Usually rear tipper tractor trailers are used for transporting various construction materials such as rocks, sand, stones, or even coal.

When working, the hydraulic cylinder gives strength to lift the front part of the tipper, and the cargo will slide down spontaneously by gravity. According to the info we mentioned above, you don’t need to worry about scratching as the tipper is made of high-tensile Hardox steel. This unloading way is easier and can greatly save your laboring cost ( you don’t need to hire people for unloading).

It is worth noting that the rear tipper is a perfect semi trailer to carry goods with a large rest angle. The rear tipper is suitable for cargo with a large rest angle, so the maximum length is 12m.

2.2 Side Tipper

The side tipper is also common in the market. Similar to the rear tipper, it can also carry construction materials, but the side tipper allows you to unload the cargo by the side door. 

A hydraulic cylinder is installed on the other side to make the tipper unload by the side door. The reason why use this design is 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 tipper trailer can help us load bigger and more goods. This is the unparalleled feature of this model.

Also, the steel plate is made of Hardox high-strength type, which prevents damages that may happen during the unloading process.

3. Types of Tilting Systems

3.1 Direct-Push Type

This is the most common way to unload the cargo. The mechanism is simple. Just push up the trailer and wait for the cargo to slide off. The bed plate on the trailer is equipped with a towing van, when finishing the unloading, it just uses the towing van to withdraw the tipper quickly and easily.

There is also a towing bar hinged to the sliding mechanism connected under the trailer’s bed. The bar is also linked by a connecting rod and the wheel, which makes it stabler. 

When the sliding hinge slides to the back, shape changes happen to the rod-frame-bed arrangement while the trailer continues to tip. 

Due to the reasonable design, you can lock the trailer in a designated position and the tipper can still be tilted back for the bed plate, then be at a higher horizontal level than in the running state.

The direct-push design can be fixed at the front, the rear, or the middle section, and the front push can be simple in structure and can give the operation a longer stroke.

3.2 Link Rods Type

The link rod type has a more complex working mechanism but with higher working efficiency than the direct push type. Same to the direct push, it also supports the tipper upwards to offload the materials. The tow bar is connected to the tipper bed plate through many connection rods to slide to achieve the lifting process.

As the tipper continues rising, the rods adjust themselves to create a balance and uniform strength on the van to reduce the thrust. Then the hydraulic cylinder works efficiently as it rises.

4. Classification of Van Body Type

4.1 The Box Type

The box tipper semi trailer has a rectangular hopper and is simple in structure to bear hard and rough materials for your use. But the tow bar has been strengthened to support towing forces while working.

Also, to counteract the thrust forces, Panda designs the tow bar with better quality to ensure stable working performance during tipping. It can greatly improve driving safety.

The box type is the most ordinary model all over the world for its sturdy quality and high efficiency. Speaking of the sturdy, the front end of the tow bar is designed with a fastening with a coupling part, and there are 2 fixing points at least on the bar’s surface to help fix the bed plate by locking the trailer on the road or in other terrible road conditions.

4.2 The U Type

The U-type tipper trailer is quite a pop star in Panda Mech’s catalog. Its’ feature is the shape of the tanker. As you can see in the picture below, this type of trailer has a bending on the corners, and this is to facilitate the unloading operation by improving the unloading speed. Also, it can unload bulky goods with no residue stuck in the corners. At present, it is the most efficient model in tipper semi trailer.

To enhance the wearing-resistant ability, the tanker plate is made of highly strengthened one-piece steel. This can prevent rupture or torsion in the working process and provide a longer service life.

The U-type tipper semi trailer is usually with lightweight but can transport large loads stably and quickly. The center of gravity of this semi is lower, which can guarantee safety in the driving process.

The Panda Mech dump semi trailer is the one that can meet these requirements and help to complete your work efficiently.

As we all know, a dump truck trailer is usually used for transporting aggregates, sand, and asphalt… These rough and abrasive materials need a highly strengthened steel plate to prevent crush and torsion. For this we use Hardox steel with 500 HBW, such a design can also guarantee operation safety.

The flat floor under the round tanker helps lower the center of gravity, and this can also greatly increase the wearing-resistant ability as well as the driving safety.

Panda’s dump semi trailer loading capacity is usually from 30 to 80 tons. The whole structure has been designed to bear heavy loads and keep it stable while driving on terrible roads.

The Loading Capacity

If you are to load bigger or more loads, choosing the rear tipper is the best choice. It can provide a fast unloading speed with convenience to free manual operation. 

It is also suitable for two materials that are hard to handle, such as demotion debris. Due to the tough platform, structure, and tipper hopper, it can fight against harsh abrasion and crush.

The Appropriate Model

Before placing the order, there are two points that you need to know as thoroughly as possible. One is the dimension of your unloading space. This point determines the model you will choose. As we mentioned above, the side tipper trailer is good at offloading at smaller places while the rear tipper is more suitable at wider places. So be clear about the unloading space dimension before choosing the model. Also, if you are not sure which one is appropriate, welcome to contact us.

Another point is the size of your cargo. Though they are all debris, some are smaller. Under such conditions, rear tipper with U-shape is better for you. It can provide fast unloading thoroughly. But if the debris is larger and heavier, then choosing a side tipper can never be wrong.

The Stable Design

The hydraulic rams offer great power when dumping. This requires a higher-quality cylinder. Make sure the cylinder is from world-famous brands, such as HYVA used by Panda. This will give you a firm backup when dealing with a heavy-duty job.

The reason why we should choose such a cylinder is that it is stabler in holding up the tipper. As a result, it can guarantee a stable offloading process as well as the operators’ safety.

The rational trailer structure design is another thing you need to check carefully. These include the design and the welding seams. If possible, go to factory to check whether the trailer structure is compact enough and whether the welding seams are closely connected with no obvious juncture. As it were, these concerns the safety and life while you are on the road.

If It Is Made of High-tensile Material

In market, there is various steel and the quality is mixed. In that case, it is important to select the high-quality one.

The best steel is Hardox steel. Panda has used Hardox steel for tipper trailer manufacturing for over 10 years. The biggest advantage of this material is the high-strength texture. It can serve for over 7 years. With the polyurethane painting on, the whole tipper semi trailer will be free of rupture and torsion, neither corrosion nor rust.
