What Is a Lowbed Semi-Trailer?

A lowbed semi-trailer, also called a lowboy, is a specialized semi trailer designed for transporting large and heavy equipment with high ground clearance or oversized height. By lowering the main cargo deck, it enables transport without exceeding legal height restrictions on public roads.

Lowbed trailers are most commonly used in industries like:

• Construction and infrastructure

• Mining and energy

• Military logistics

• Oversized cargo delivery services

They are built to handle large and heavy machinery such as excavators, bulldozers, cranes, and industrial modules.

Lowbed vs. Flatbed vs. Low Loader Trailers

Each trailer type serves a unique purpose. Here’s how they compare:

Lowbed trailers stand out for their lower center of gravity and ability to transport oversized loads with improved road safety and clearance.

Configurations for Different Load Requirements

CLW Group offers modular designs to adapt to different weight classes and transport needs. Options include:

Axle Options

• 2 Axles: For lighter construction vehicles

• 3 Axles: Ideal for mid-range payloads (common across the industry)

• 4 or 5 Axles: For ultra-heavy duty jobs involving 80+ tons

Ramp Mechanisms

• Manual folding ramps for straightforward loading

• Hydraulic ramps for safer loading of wheeled or tracked equipment

Deck Designs

• Straight flat deck or sloped loading deck

• Extendable deck sections for long cargo

• Reinforced deck with anti-slip surface

Common Industries That Use Low Bed Semi-Trailers

These trailers are used to transport heavy vehicles and oversized equipment across various sectors:

• Construction firms for shifting bulldozers, loaders, and rollers

• Wind and energy projects for large turbine parts

• Oil & gas operations for mobile rigs and steel modules

• Agricultural equipment transport such as combine harvesters

• Government and military for tanks and armored carriers

Their robust construction and loading adaptability make them essential in any logistics fleet focused on heavy transport.

CLW Lowbed Models – Reference Table

CLW pricing varies based on deck material, ramp systems, and local delivery requirements.

Ramp Systems for Loading Large Equipment

Loading heavy machinery like an excavator or crane requires ramp systems that offer:

• Stability under high weight

• Secure footing for tracked vehicles

• Adequate length to reduce slope angle

CLW lowbed trailers support:

• Rear-mounted spring ramps

• Double hydraulic foldable ramps

• Wide surface ramps with anti-slip layers

These ensure that even 100-ton heavy machinery can be loaded safely and quickly.

Gooseneck Customization and Fifth Wheel Matching

Our trailers are equipped to match standard fifth wheel heights of 1050–1300 mm. The gooseneck design plays a major role in connecting to the tractor securely and handling vertical load transfer.

Options include:

• Fixed gooseneck for basic setups

• Removable gooseneck (RGN) for loading from the front

• Hydraulic gooseneck for enhanced adjustment flexibility

This makes it easier to align the trailer with various semi-truck brands including Dongfeng, Shacman, Sinotruk, and FAW.

Axle Spacing and Road Compliance

Trailer axle spacing and number of axles are critical for staying within legal road limits. Our engineering ensures proper distribution of:

• Net weight and load balance

• Tire pressure and road surface force

• Compliance with regional transport laws

Each axle low bed model is tested under full load to ensure high safety margins and reliability over long hauls.
