A lowboy (low-loader in British English, low-bed in western Canada and South Africa or float in Australia and eastern Canada) is a semi-trailer with two drops in deck height: one right after the gooseneck and one right before the wheels. This allows the deck to be extremely low compared with other trailers. It offers the ability to carry legal loads up to 12 ft (3.66 m) tall, which other trailers cannot. Lowboys are used to haul heavy equipment such as bulldozers and large industrial equipment.

History of Low Bed Trailers

The first lowboy trailer was invented in the 1920s; it featured a riveted gooseneck and solid rubber tires. The first detachable gooseneck trailer, referred to as an RGN (Removable goose neck), was invented in 1958.

Types of Low Bed Trailers

Several types of lowboy trailers exist, catering to a wide range of tasks, including:

• Fixed gooseneck (FGN): Allows a longer deck length and has the lightest weight. These are lower trailers than normal, with low-profile tires, usually with drop ramps in the rear to facilitate loading of equipment, but are not actually considered "lowboys". The neck is arched in such a way that, when lowered, it becomes a ramp, thus allowing the front tires of equipment to be pulled onto the deck.
• Fixed-neck: The neck is fixed to the trailer, offering the lightest weight but sacrificing the ability to detach and load over the front.
• Hydraulic detachable gooseneck (hydraulic RGN or HRGN): Fastest and easiest to detach, at the expense of weight and deck length. It is the most common and versatile of lowboy trailers; the gooseneck is detached using large hydraulic cylinders to raise and lower the trailer and a small cylinder shores the neck to the truck, removing the neck so a large piece of equipment can be driven over the front onto the deck of the trailer for transport. The hydraulics can be run from the truck auxiliary or from a pony motor mounted in the neck of the trailer.
• Mechanically-detachable gooseneck (mechanical RGN or MRGN): Usually lighter than the hydraulic detachable gooseneck but users sacrifice ease and speed of detaching. Used for long specialty hauls.
• Mechanical folding gooseneck (MFGN): The deck folds down to ground level to provide a ramp for trailer loading.

Key Features of Low Bed Trailers

Suspension Types

• Spring ride: Lowest cost; however, it has a rougher ride and adds more stress to the trailer.
• Air-ride: Provides a smoother ride, adding to the life of the trailer frame. Air rides can also be adjusted for a higher or lower deck height.
• Hydraulic suspension: An oil-filled system, allowing wide variation of axle movement.
• Independent suspension: A double wishbone, hydraulic suspension that offers greater stability, greater steering angle, and more travel.

Structural Types

• Main structural steel type: Mill-rolled beams save money; although they are around 4,000–6,000 lb (1,814–2,722 kg) heavier, they also reverse camber after a few years due to the much-lower strength of the main beams.
• T1 or A514 beams: These beams save weight and allow more versatile engineering of the trailer; they are cut to the highest-strength shape possible and welded together.

Characteristics of Low Bed Trailers

Application of Low Bed Trailers

Low bed semi-trailers (also called low boy semi-trailers) are typically used to transport heavy trucks (e.g., Tractor trucks, Buses, and special vehicles), rail vehicles, mining machinery, forestry machinery, agricultural machinery (such as excavators, bulldozers, loaders, paver, cranes, etc.), and other heavy cargos. The center of gravity of a low bed trailer is lower, enhancing its stability and safety, and it has a stronger ability to transport over-height cargo and navigate through overhead obstacles.

Structure and Loading Method

The low bed trailer usually adopts a concave beam type (or well type) frame. The front part of the frame is the goose neck (The Kingpin in the front part of the goose neck is connected with the fifth wheel in the tractor truck and the rear part of the goose neck is connected with the trailer chassis). The middle part is the cargo platform (the lowest part of the frame), and the rear part is the wheel frame (including the wheels). When loading mechanical equipment, it is usually done from the rear part of the trailer by moving the equipment from the rear wheel or removing the wheels, then fixing the mechanical equipment onto the semi-trailer.

Characteristics

• The series of Low bed trailers come in flat type, concave beam type, and tire exposed structure. The I beam adopts straight or goose neck type. The chassis of the trailer is staircase type, featuring high stiffness and strength.
• The cargo platform is designed to be as low as possible, ensuring transportation stability. It is suitable for transporting various construction machinery, large equipment, and steel.
• Equipped with tri-axles balance type, biaxial balance type, or rigid suspension. The low bed trailer features a mass balance piece between the front and rear leaf springs, allowing the deflection of the front and rear leaf springs to change by the same amount, thereby balancing the front and rear axles.
• Designed using advanced computer-aided design software to optimize the trailer flexibly and diversely. The dimensions of the cargo platform can be customized to meet the transportation requirements of various special goods.
