What is a lowboy trailer?lowboy trailer

The lowboy trailer has a drop deck, one end –gooseneck –this end hooks to the truck, the other end at the rear wheels, drops down and is a few inches off the ground.

The first lowboy was invented in the 1920’s and had a row of rear tires made of solid rubber, as many as 8-tiers, across the rear of the trailer. The trailer was loaded from the rear; you would drive up over the rear tires and onto the trailer deck.

The first lowboy trailer with a detachable gooseneck [gooseneck is the front of the trailer that hooks to the truck] was invented in the late 1950’s. Today all detachable trailers load from the front [gooseneck end] of the trailer; this allows the equipment to drive on the trailer without the use of loading ramps. Most all new detachable lowboy trailers have a hydraulic system that operates a hydraulic ram that raises the trailer to hook the trailer unit after it is loaded.

All new type lowboy trailers are towed by a semi-truck, all have air brakes, all are two axles’ trailers with 8-tires, larger heavy trailers have three axles with 12-tires, some special heavy duty trailers have four axles, and there are even very heavy duty trailers with more than 4-axles.

Some lowboys trailers are a beam type trailer which means the large heavy equipment is carried with a center [2-beams] under the piece of equipment, this allows a taller load, the load can be only inches off the highway, this type trailer can have 3-axles and ever 4 rear axles, some unit can carry up 100 tons. This beam type lowboy has a gooseneck that hooks to the semi-truck, the beam trailer use the air brakes system, and a hydraulic system.

There are other types of lowboy trailers and sometimes the lowboy has been called a lowbed trailer, they are the same trailer. The lowboy trailers have a large range of weight capacity from 10 ton to 100 tons and over with special units. There may be other trailer units not mentioned.
