Detailed Description:
- Capacity & Versatility:With load capacities from 40 to 100 metric tons and deck lengths of 40–60 feet, these trailers can be configured with hydraulic sliding modules and extension beams to accommodate a vast range of indivisible loads.
- Advanced Loading Engineering:The hydraulic gooseneck can be lowered to ground level, creating a gentle ramp angle. Combined with a winch system, it allows for safe loading of non-powered equipment like industrial generators, dredgers, and bridge sections.
- Superior Safety & Control: Features include independent suspension on each axle, dual-circuit air brakes, and an integrated load monitoring system that provides real-time weight distribution data to the driver, preventing overloading incidents.
- Durability in Demanding Conditions:The main deck is made of high-yield steel T1 (100,000 PSI) and is treated with anti-slip aluminum oxide coating, while all hydraulic components are IP67-rated for dust and water resistance.
-Ideal for: Heavy engineering projects, power plant equipment relocation, wind turbine component transport, and military vehicle movement.

Frequently Asked Questions
What equipment can this low bed semi-trailer carry?
Low bed semi-trailers carry excavators, bulldozers, wheel loaders, road rollers and other oversized machinery. This 4-axle unit is rated for 40T, which covers most 20–40 tonne construction machines with margin for the trailer itself.
What is the loading height and deck length?
The low deck keeps the centre of gravity low so tall machines clear bridges and overhead lines. We build to your machine dimensions — send us the length, width, height and weight of the equipment and we confirm the deck and ramp geometry before production.
Mechanical or hydraulic ramp — which do I need?
Mechanical spring ramps are simpler and cheaper to maintain. Hydraulic or folding ramps speed up loading and are worth the extra cost if the trailer does frequent, repeated machine moves.
Can it be extended for long loads?
Yes. Extendable and detachable gooseneck versions are available for long or unusually tall cargo. Tell us the largest machine you plan to move and we will specify the right variant.
What about axles, tyres and braking?
This trailer runs 4-axle axles with dual tyres and a dual-line air brake system with ABS. Tyre size is matched to the load rating so the trailer stays within its legal axle load in your market.
