What Is A Lowboy Trailer?
Lowboy Trailers | The Meaning
A lowboy (low loader in British English, low-bed in western Canada and South Africa or float in Australia) is a semi-trailer with two drops in deck height: one right after the gooseneck and one right prior to the wheels. This allows the deck to be exceptionally low compared to other trailers. It provides the ability to bring legal loads up to 12 feet (3.66 m) tall, which other trailers can not. Lowboys are utilized to haul heavy equipment such as bulldozers, commercial equipment and so on
Lowboy Trailer History
The first lowboy trailer was invented in the 1920s; it included a riveted gooseneck and solid rubber tires. The first detachable gooseneck trailer, referred to as an RGN (Removable goose neck), was invented in 1958.
Lowboy Trailer Types
The lowboy trailer is available in a number of types, for a vast array of tasks.
Some lowboy types are:
– Fixed gooseneck (FGN): allows a longer deck length and has the lightest weight. These are lower trailers than typical, with low-profile tires, usually with drop ramps in the back to help with loading of equipment, however are not in fact thought about “lowboys”. The neck is arched in such a way, that it when decreased, it becomes a ramp hence enabling the front tires of equipment to be pulled onto the deck.
– Fixed-neck: the neck is fixed to trailers; provides the lightest weight, but sacrifices the ability to separate and load over the front
– Hydraulic detachable gooseneck (hydraulic RGN or HRGN)): fastest and most convenient to separate, at the expense of weight and deck length. It is the most common and flexible of lowboy trailers; the gooseneck is removed utilizing big hydraulic cylinders to raise and decrease the trailer and a little cylinder shores the neck to the truck, eliminating the neck so a big piece of equipment can be driven over the front onto the deck of the trailer for transport. The hydraulics can be ranged from the truck auxiliary or from a pony motor mounted in the neck of the trailer.
– Mechanically-detachable gooseneck (mechanical RGN or MRGN): while normally lighter than the hydraulic detachable gooseneck, users compromise ease and speed of removing. Used for long specialized hauls.
– Mechanical folding gooseneck (MFGN): The deck folds down to ground level to supply a ramp for from trailer loading.
Lowboy Trailer Features
Lowboy trailer features include:
– Spring ride: least expensive cost; nevertheless, it has a rougher trip and adds more tension to the trailer
– Air-ride: really smooth trip, adding to the life of the trailer frame. Air trips can also be adjusted for a higher or lower deck height
– Hydraulic suspension: an oil-filled system, allowing wide variation of axle motion
– Independent suspension: a double wishbone, hydraulic suspension, which uses more stability, higher steering angle and more travel
– Main structural steel type: mill rolled beams save loan; although being 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 primary beams.
– T1 or A514 beams save weight and permit more flexible engineering of the trailer; they are cut to the highest-strength shape possible and welded together.
With all the different specific trailers being pulled by freight transportation companies across the world, covering every stretch of road you can possibly imagine … more than likely you have actually seen your fair share of lowboy trailers (although you might not have actually understood it). A lowboy trailer, likewise known as a double drop, low loader, low-bed, or a float depending upon what part of the world you are in, is a semi-trailer with a drop deck. A lowboy trailer has two drops in the deck, the very first drop is best behind the gooseneck and the second drop is right prior to the wheels, this allows the trailer to sit very low to the ground. The drop in the trailer is designed to enable the capability to deliver extra-large products or equipment that exceeds regular height restrictions for transportation (which is generally any freight over 8 ′ high).
A lowboy trailer is typically utilized to haul heavy equipment and equipment, such as excavators, bulldozers, and other large building and construction equipment. The lowboy trailer is ideal for carrying big equipment like this due to the fact that they are normally tall and large and would go beyond standard legal height and weight restrictions. The maximum weight for a 2 axle lowboy trailer is 40,000 pounds, however the weight limit can be increased up to 80,000 pounds overall weight of trailer, and load depending upon the variety of axles needed. The lowboy trailer is capable of dealing with loads with an optimum height of up to 14 feet high. For dependable trucking services and equipment transportation, the lowboy trailer is basically developed to transport oversized items that often go beyond the legal height requirements of transportation by a flatbed trailer.
Lowboys Optimum Dimensions:
– Lowboy Well Length 24 feet– 29.6 ft.
– Lowboy Well Height 18 in– 24 in.
– Legal Width 8.5 ft.
– Legal Freight Height 11.5 feet– 12 ft.
– Legal Overall Load Height 14 ft.
– Lowboys maximum overall weight is 40,000 pounds for a standard 2-axle Lowboy Trailer; but can take additional weight of approximately 80,000 pounds depending on the variety of axles the trailer possesses (weight of the trailer and weight of the load totaled).
How is a Lowboy Trailer Different from a RGN Trailer?
Lowboy and RGN Trailers
Trying to choose the best trailer to carry your freight can be an overwhelming job. Both Lowboy and RGN trailers are outstanding for bring tall and long freight, so, which will work best for your shipment?
Here are the distinctions:
Lowboy trailers were created in the 1920s and are unpowered trailers typically utilized in carrying and transferring taller items and products. The items normally transported by lowboy trailers are taller than the legal height of products that can be carried by flatbeds, and are normally industrial equipment like bulldozers.
Lowboy Trailer Dimensions
Here are the maximum dimensions for a lowboy trailer:
– Max freight weight: 40,000 pounds (with two axles) and up to 80,000 pounds with additional axles.
– Max well length: 24 ft. to 29.6 ft.
– Max well height: 18 in. to 24 in.
– Max legal width: 8.5 ft.
– Max legal freight height: 11.5 ft. to 12 ft.
– Max legal overall load height: 14 ft.
RGN, or removable gooseneck trailers were invented in 1958 and are terrific for carrying long and tall freight. The front detaches, enabling the trailer to be decreased to the ground to develop a ramp. For this factor, loads are normally driven onto the trailer, like trucks and other motorized equipment. RGN trailers can increase to 20+ axles, so they can carry freight as much as 150,000 pounds.
RGN Trailer Dimensions
Here are the optimum dimensions for a RGN trailer:
– Max freight weight: 42,000 pounds.
– Max well length: 29 ft. (primary deck).
– Max well width: 8.5 ft.
– Max legal freight height: 11.6 ft.
As you can see, lowboy and RGN trailers serve a similar function. However, depending on your needs, one might serve you better than the other. If it would be much easier to own your delivery onto your trailer, RGN trailers would be a better fit. If you’re looking for something a little less costly, a lowboy would be better, because RGNs can run you a bit more because they’re specialized.
