Characteristics of wood transport semi-trailer

Timber transport semi-trailer is a heavy-duty trailer designed specifically for timber transport, with the following core characteristics:

1、 Structural characteristics
Rear axle design: The axle is placed behind the center of gravity of the vehicle and connected to the tractor (such as the front of a truck) through a traction pin, forming a semi-trailer structure. This design allows the tractor to bear some of the weight, improving transportation stability while reducing the weight of the trailer and increasing the payload.
Diversified cargo platform structure:
Flat type: The cargo platform is flat and open, with multiple sets of detachable or foldable columns on both sides to prevent the wood from sliding sideways; The tail is equipped with a rotating or hydraulic lifting carrier (goose neck) to prevent long wood from slipping off.
Fence board: There are detachable fence boards around the perimeter, and the cargo box structure is enclosed to prevent short wood from scattering; Some models are equipped with self dumping function to improve unloading efficiency.
Skeleton style: No cargo platform, only retaining the frame structure, suitable for standard containers or specialized wooden boxes, facilitating cross-border or multimodal transportation.
High strength material: The frame is made of high-strength steel (such as Q345B) or aluminum alloy material, with excellent tensile strength and bending resistance, suitable for heavy load requirements.
2、 Performance advantages
Strong carrying capacity:
The length of the cargo box can reach 11 meters to 17.5 meters, with a single transport volume far exceeding that of ordinary trucks, especially suitable for the transportation of bulk timber (such as logs and boards).
The total weight can reach 40 to 70 tons, meeting the transportation needs of heavy timber.
High transportation efficiency:
The tractor and trailer can be separated, and the tractor can quickly tow other trailers after unloading, reducing waiting time.
Adapt to various transportation scenarios, such as transportation from forest areas, logging sites to processing plants, as well as cross-border or multimodal transport.
Significant cost-effectiveness:
The unit cost of timber transportation has been reduced by 30% -40%, and the fuel consumption for long-distance transportation is 20% -30% lower than that of ordinary trucks.
Lightweight design (such as aluminum alloy material) further reduces self weight and enhances payload capacity.
Safety and stability:
Low center of gravity reduces the risk of rollover.
Equipped with ABS, EBS and other brake assist systems to improve braking response speed.
The fence style and skeleton style designs prevent wood from scattering and reduce the risk of accidents.
3、 Type and Applicable Scenarios
Long haul timber semi-trailer:
Features: Flat or skeleton frame, no box board design, suitable for transporting long logs.
Applicable scenarios: Transportation from forest areas, logging sites to processing plants.
Fence type wood transport semi-trailer:
Features: Removable railings are installed around the perimeter, the cargo box is enclosed, and some models are equipped with self dumping function.
Applicable scenarios: Transporting short specification timber such as sawn timber and wooden beams, commonly found in southern forest areas and around timber processing plants.
Skeleton wood transport semi-trailer:
Features: No cargo platform, compatible with standard containers, convenient for cross-border or multimodal transportation.
Applicable scenarios: Standardized wood transportation to reduce cargo loading and unloading losses.
Multi functional flatbed semi-trailer:
Features: Flat cargo platform, with reserved pile insertion holes on both sides, which can be inserted to fix wood with piles; Installing container locks can transport containers or general cargo.
Applicable scenarios: Balancing wood, container, and general cargo transportation, suitable for multi-purpose logistics needs.
Long trailer:
Features: Designed specifically for transporting long timber bundles, the front end is placed on the steering bearing device of the main transport vehicle, and the vertical load transmission belongs to the semi-trailer type.
Applicable scenarios: Long timber transportation mainly based on raw material production in the forest areas of Northeast China and Inner Mongolia.
