FRONT LOADING LOWBED SEMI TRAILER

Low-bed semi-trailers are built with a sunken drop deck that sits 0.5 to 1.2 meters above the ground. This extremely low center of gravity boosts road stability and prevents rollovers, and the streamlined low body can clear bridges and tunnels with ease while bringing down the cargo’s center of gravity.

The indented cargo deck is positioned between the front gooseneck and rear axles, which earns it alternative names like lowboy or low loader semi-trailer in certain markets. Standard payload capacities span 20 to 100 tons, while multi-axle customized versions can support loads heavier than 300 tons. Boasting a low gravity point, powerful load-bearing capacity, smooth travel performance and simple loading and unloading procedures, these trailers are perfectly suited for hauling large construction machines, heavy industrial gear, wind power components, transformers, special vehicles and steel structure products.

Front-load low-bed trailers outperform standard rear-load models by featuring an even lower center of gravity and a more gradual loading ramp, which delivers safer transport for high-value and precision machinery.

SHIYUN suggests front-loading low-bed semi-trailers for shipments of premium equipment. They are mainly available in two styles: models with hydraulically detachable goosenecks and those equipped with hydraulically foldable goosenecks

Folding gooseneck lowbed trailer

Folding gooseneck low-bed semi-trailers have seen surging sales in recent years, thanks to their straightforward, highly efficient operation, making them a well-liked choice for clients across South America and the Middle East.

Users can lower the front gooseneck all the way to ground level either by operating manual control valves or using a wireless remote controller. Construction machinery can then climb straight up the ramp formed by the folded gooseneck onto the low loading deck. This design eliminates the step of detaching the gooseneck entirely. It streamlines operational steps and enables fast, productive loading, unloading and hauling work.

Advantages of folding gooseneck lowbed trailer :

2.1. No disassembly required

The folding gooseneck needs no integral disassembly or bolt removal. It can be operated easily by one person, saving time and labor.

2.2. Convenient machinery loading & unloading

When the gooseneck is folded down, it forms a gentle slope. Excavators, road rollers and other engineering vehicles can drive on and off directly.

2.3 Greater flexibility in application

The folding gooseneck low-bed trailer is equipped with 6 hydraulic jacks under the gooseneck. Among them, 4 units realize the folding and lifting of the gooseneck, and the other 2 support the lifting of the loading platform, delivering dual functions.

During operation, the gooseneck height can be adjusted to match different fifth wheel heights. The loading platform height can also be regulated to adapt to height-limited areas such as roads, bridges and tunnels. Meanwhile, it maintains a lower cargo center of gravity for safer and more stable driving.

3.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.
• To meet customers’ diverse transportation requirements, Shiyun offers customized cargo deck designs including low concave deck and straight beam deck options

• 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.

SHIYUN produces a complete portfolio of low-bed semi-trailers that go well beyond the specs mentioned above. Full customisation services are offered to match your unique demands while complying with local traffic codes and road clearance rules of different nations.

Our low-bed semi-trailers fit all types of heavy transport assignments. Built with sturdy frames, they run reliably on the road.
