Lowboy Trailers

An essential multi-billion dollar conglomerate, the transportation industry is vital to the economic growth for any business. Whether recreational or commercial, moving people and/or products safely from one point to another are critical to a company’s bottom line. Logistical uses of planes, cars and buses, railways, boats and ships, and trucks ensure efficient yet safe conveyance of goods and/or travelers. However, specifically in the trucking industry, lowboy trailers are one of the many vehicles used to transport heavy cargo and equipment for various commercial industries, including oil and gas, construction, energy, agricultural and military. A type of flatbed semi-trailer, a lowboy has a drop deck area between the rear wheels and the gooseneck that is lowered close to the ground. Its drop deck height allows for carrying legal freight up to 12 ft. tall; compared to other trailers, this advantageous feature makes lowboys unique yet functional for heavy items. Therefore, these trailers are very useful in transporting and handling industrial payloads and gears, such as cranes, bulldozers, smaller heavy-duty trucks and other hefty devices like transformers and oilfield equipment.

Brief History and Features

Invented in the 1920s, the first lowboy trailer had a fixed gooseneck i.e., front part of the trailer that attaches to the truck, a row of solid rubber rear tires, and rear-loaded ramp. In 1958, a detachable gooseneck (also called Removable Gooseneck or RGN) was introduced onto a lowboy, eventually allowing for front-loading of a heavy item onto the trailer. Its drop deck is typically made of treated wood panels and custom steel beams that can hold and carry objects weighing 20-100 tons. Lowboy trailers use the following types of suspension:

  • Spring Ride Suspension – Cheapest, rougher ride, more stress on trailer
  • Air-Ride Suspension – Very smooth ride, adjustable for lower and higher deck height enhancing trailer deck’s life
  • Hydraulic Suspension – More efficient, oil-filled system and greater variation of axle movement
  • Independent Suspension – Double wishbone, hydraulic suspension, wider steering angle, greater stability allowing for more travel


Available for a wide range of tasks, the following types of lowboy trailers are:

  • Fixed Gooseneck (FGN) – Lightweight, longer deck height, lower than normal, low-profile tires, rear-loaded drop ramp, ramp-like and arched neck in a fixed position
  • Fixed-Neck – Linear, fixed neck, lightest weight more difficult to detach and rear-loading
  • Hydraulic Detachable Gooseneck (Hydraulic RGN or HRGN) – Most common and adaptable, fastest and easiest to detach, heavier and shorter deck, hydraulic-powered and removable arched neck
  • Mechanically-Detachable Gooseneck (Mechanical RGN or MRGN) – Lighter than hydraulic detachable gooseneck, less ease and slower to detach and ideal for long specialty transport
  • Mechanical Folding Gooseneck (MFGN) – Foldable gooseneck, converting to a front-loading, ground-level ramp.
