FRONT LOADING LOWBED SEMI TRAILER

Low-bed semi-trailers adopt a sunken drop-deck layout, with deck height ranging from 0.8 to 1.2 meters. The extremely low center of gravity enhances driving stability and prevents rollover accidents. Meanwhile, its streamlined low-height design allows smooth passage under bridges and tunnels and reduces the center of gravity of loaded goods.

As its cargo platform is recessed between the front gooseneck and rear axle groups, this type of trailer is also known as lowboy or low loader semi-trailer in many overseas markets. Its standard payload capacity covers 20 to 100 tons, while multi-axle customized variants can carry loads over 300 tons. Boasting a low gravity point, powerful load-bearing capacity, smooth traveling performance and convenient loading and unloading, it is perfectly applicable to transport large construction machinery, heavy industrial equipment, wind power components, transformers, special vehicles and steel structural parts.

In contrast to conventional rear-load low-bed trailers, front-load designs come with an even lower gravity center and a more gradual loading ramp, enabling safer transportation of high-value and precision mechanical equipment.

SHIYUN suggests selecting front-loading low-bed semi-trailers for the shipment of premium equipment, which mainly fall into two categories: models with hydraulically detachable goosenecks and those equipped with hydraulically foldable goosenecks.

1. Detachable gooseneck lowbed trailer

Detachable gooseneck low-bed semi-trailers have been the cornerstone of SHIYUN’s impressive expansion and advancement within the semi-trailer manufacturing sector.

This equipment, also named removable gooseneck low-bed trailer, is widely abbreviated as RGN low-bed semi-trailer or Challenger-style low-bed trailer. Drawing on a wealth of end-user real-world operating records covering both successful applications and operational drawbacks, SHIYUN carries out ongoing technical innovations and structural refinements. Thanks to this accumulation of practical experience, we possess unmatched expertise in designing this trailer model, with our technical capabilities sitting among the nation’s leading tier.

Numerous competitors have attempted to duplicate SHIYUN’s trailers without success. They are merely able to mimic the exterior outline, yet incapable of recreating the intricate precision and proprietary core technology embedded in our gooseneck design. Most manufacturers on the market can only achieve basic separation of the detachable gooseneck, lacking the ability to align, assemble and connect the gooseneck and main trailer body smoothly and efficiently.

By contrast, SHIYUN’s detachable gooseneck low-bed semi-trailer enables fast disassembly, assembly and accurate alignment in an efficient manner. This superior high-performance functionality represents not only SHIYUN’s exclusive competitive edge, but also an unmatched selling point that rival brands cannot reproduce.

Advantages of detachable gooseneck lowbed trailer :

1.1. Easy cargo loading and unloading.

Small ladders are equipped under the gooseneck and at the front of the loading platform.Large engineering machinery can drive onto the deck directly from the front after removing the gooseneck, safer and more efficient.

1.2. Adjustable Height

The hydraulic gooseneck can flexibly adjust the height of the front loading platform, greatly improving the trailer’s trafficability and enabling easy passage under bridges, tunnels and height-restricted sections.

1.3. Lower Cargo Center of Gravity

Adopting a hydraulic gooseneck and concave beam design,after the gooseneck is separated from the loading platform, equipment can be driven onto the loading platform from the front. It effectively lowers the cargo center of gravity, greatly improving driving stability and transportation safety.

1.4 Precision Connection Pin Position

The detachable gooseneck low-bed semi-trailer manufactured by SHIYUN adopts high-precision craftsmanship for both positioning pins and load-bearing tandem pins. With accurate alignment and perfect fitting, it greatly improves assembly and docking efficiency and makes operation more efficient.

1.5 Great flexibility in application

It is equipped with multi-functional hydraulic cylinders, including positioning cylinders, support cylinders and hydraulic lifting cylinders.The coordinated operation of multiple hydraulic cylinders realizes efficient manipulation of the detachable gooseneck.

2.Features:

• SHIYUN lowbed semi-trailers are mainly constructed from high-strength structural steel Q550 or Q460, with a yield strength> 620MPa.Compared with ordinary Q345 steel used for semi-trailers, our steel features higher strength and better durability, which greatly improves load capacity and life time while effectively reducing the overall weight.Reasonable structural design and precise camber fabrication have earned SHIYUN lowboy trailers a broad market and excellent reputation.
• SHIYUN front loading lowbed semi-trailer is generally equipped with two types of power control systems: one is a hydraulic power unit, and the other is the PTO (Power Take-Off) of the tractor. Both can precisely control the hydraulic cylinder on the gooseneck to achieve lifting, disassembly, assembly, hoisting and other operations.

• SHIYUN lowbed semi-trailers can be designed with various widths to meet different requirements.The standard minimum width is 2 meters, while most customers choose a width between 2.5 meters and 3 meters.We can also customize trailers with a maximum width of up to 6 meters as per your needs.In addition to fixed-width designs, we can equip extendable brackets to achieve flexible conversion between different loading widths.

• Due to the overall long length of multi-axle low-bed semi-trailers, equipped with a length telescopic structure can greatly improve the vehicle’s turning performance.The telescopic mechanism adopts pneumatic control pins. The pneumatic locking pins are used to adjust the telescopic length and fix the positioning. It supports single-section telescopic movement, as well as single and double-section combined telescopic operation.For the main beam, both double-beam telescopic type and single-beam telescopic type are available.The perfect telescopic extendable beam design is another key advantage of SHIYUN low bed semi-trailers.Unlike structures made of conventional Q345 steel, we use high-strength steel plates Q550, ensuring the telescopic beams resist deformation, extend and retract smoothly and efficiently, and completely eliminate the risk of failing to retract after extension.

• SHIYUN offer both fully enclosed tire design and exposed tire design to meet the transportation requirements of different cargoes.The exposed tire design has further lowers the platform height to accommodate taller cargo.
• A wide range of suspension systems are available.SHIYUN lowbed trailers can be equipped with leaf spring suspension with equalizer beams , air suspension, cantilever suspension(bogie) ,hydraulic lifting suspension, as well as the dedicated suspension for hydraulic modular trailers.Air suspension can be equipped with WABCO lifting control handles, and hydraulic suspension can be equipped with dedicated hydraulic control handles.
• To increase the load capacity of the front kingpin, a front dolly can be equipped to improve the rated load and bearing capacity of the kingpin assembly.

• Normally, goods are loaded and unloaded via the front ramp of the front-mounted low loader. We can also customize low loaders with rear ramps according to customers’ requirements.

• SHIYUN low loader trailers are equipped with renowned components, such as BPW, Fuwa, CTC, Jost,AN and others. These well-known brands feature high reliability, longer service life, and higher operating efficiency.

• For axle suspension, standard through axles are available in 2-axle, 3-axle, 4-axle, 5-axle and even 6-axle configurations. Optional choices also include line axles, modular axles and modular hydraulic steering axles.

• The loading platform can be made of checker plate or wooden planks, featuring sufficient thickness and high strength.
• Flip-type axle splicing structure can be adopted to flexibly add or reduce axles and adjust axle load capacity.

The low-bed semi-trailers manufactured by SHIYUN are available in a wide range of models, not limited to the above specifications. They can be fully customized according to your requirements to meet the regulatory standards and road access requirements of different countries.

Our low-bed semi-trailers are suitable for heavy-duty transportation in various scenarios, featuring a solid structure and stable operation. With professional performance, we help boost efficient logistics and are committed to creating greater value for customers with reliable quality.
