3. What Are The Advantages Of TRUCKMAN AUTO Dump Semi Trailer ?


From product design and development, production process, shipment and after-sales service, our sales are very

professional. They will recommend a suitable semi trailer according to the working condition of the dump semi trailer,

and will pay attention to the rust problem during the shipment process, and provide timely and professional

after-sales service feedback.


A. Enhanced Thickness Of Dump Semi Trailer Chassis Parts:

The TRUCKMAN AUTO dump semi trailer is suitable for very bad road conditions, because we have strengthened the

thickness of the tire rim and the leaf spring. The tire rim is 18mm thick and the leaf spring is designed with

120x16mmx10layer In addition, the thickness of the main beam and the side beam is 2mm thicker than the thickness

of the dump semi trailer of other factories.


B. Perfect Shipment:


Since the main material of the dump semi trailer is iron, humid air and sea water during the shipping process will cause

rust problems to the dump semi-trailer. However, TRUCKMAN AUTO's dump semi trailer does not have this problem,

because we spray wax on the dump semi trailer before the departure, and after loading it on the ship, it will be covered

with two layers of tarpaulin and two layers of mesh. The tarp and mesh will perfectly wrap the entire dump semi trailer

and isolate the influence of sea water and humid air on the vehicle.


4. What Are The Unloading Methods Of Dump Semi Trailer ?


There are two main types of dump semi trailer unloading methods, side unloading and rear unloading, both methods have

their own advantages and disadvantages, as follow:


A. Requirements For Terrain:

The rear unloading dump semi trailer requires a large, wide and flat unloading site.The side unloading dump semi trailer

requires a flat unloading site only.


B. Rollover Accident:

Compared with rear unloading dump semi trailer, the side unloading dump semi trailer rollover accident is low.


C. Unloading Residual Degree:

The rear unloading dump semi trailer has low unloading residue and quicker unloading time.


D. Purchase Cost:

The purchase cost of the side unloading dump semi trailer is low, and the maintenance is also convenient.


5. What Are The Cargo Box Types Of Dump Semi Trailer ?


The cargo box types of dump semi trailers are rectangular bucket and U-shaped bucket. U shape bucket have

many advantage compare with rectangular shape bucket, as follow:


A. U Shape Bucket: Among them, the U-shaped bucket is suitable for transporting sand, clay and other goods. Because

the corners of the U-shaped bucket are curved transitions, there are no dead corners, and it is not easy to stick to the

box body during unloading. In addition, through the use of high-strength plates and structural optimization, the U-shaped

bucket not only ensures the strength of the box, but also reduces its own weight. The thickness of the board is reduced

by about 20%, which effectively improves the load utilization factor. In addition, the center of gravity of the U-bucket is

low, and the overturning rate of the vehicle in high-speed turns is also low, which is safer.


B. Rectangular Bucket: With low purchase cost, convenient maintenance, simple structure, suitable for general cargo

transportation, such as sand and gravel, etc.


6. What Are The Differences Between Dump Trucks And Dump Semi Trailer ?


A. The Weight Of The Cargo Carried Is Different:

The size of the dump truck itself is small, and the weight of the loaded cargo is also small when carrying the cargo.

Because of the small body, the operation is very convenient, the dump truck is very convenient to carry goods drive

at the road is narrow and rugged road. However, if it is a large coal mine or a large-scale project, truck freight requires

much and more labor cost than dump semi trailers. Dump semi trailers are more suitable for use in these aspects,

and the carrying capacity is several times that of dump truck each time. Can shorten the engineering time,

can improve the efficiency.


B. Different Dumping Methods:

The coal mine needs to be transported to a certain place, and then loaded and unloaded. The dump truck only can

unloading goods via read unloading type It is inconvenient, which requires the dump truck to adjust. Unload the goods in

accordance with the regulations. Due to the limitation of the site, it is very inconvenient to unload the goods. However,

side unloading dump semi trailer will be no inconvenience due to the site, and it is more convenient to unload the goods.

long distance transport, no working site request.

take-off device to drive the hydraulic pump to work. The hydraulic pump sucks the hydraulic oil in the hydraulic oil tank

through the low-pressure oil inlet pipe and produces high-pressure oil for output. The gear pump outputs The

high-pressure oil enters the lift valve through the high-pressure oil pipe, and the lift valve delivers the high-pressure

oil to the oil cylinder or drains to the hydraulic oil tank under the control of the air control valve to realize the lifting,

stopping and lowering functions of the hydraulic oil cylinder.
