- Recommended Products
High-Efficiency Mechanical Spring Ramps: Built with premium double-spring tension assistance, these heavy rear ramps can be easily deployed or raised manually by a single operator. The ramp surface is heavily reinforced with anti-slip steel bars and support lattices, providing a rock-solid, zero-slip climbing angle for 80-ton tracked machinery.
Q345B High-Tensile Submerged-Arc Beams: The structural spine of the trailer is constructed using high-tensile Q345B carbon steel. The main beams are processed via continuous automated submerged-arc welding, eliminating weak spots and preventing beam cracking, twisting, or sagging under heavy, concentrated equipment tracking.
Optimized 4-Axle Load Sharing: Integrating four heavy-duty axles distributes the immense cargo load across 16 radial tires instead of 12. This pattern reduces single-tire wear, enhances tracking stability on unpaved site roads, and helps your fleet bypass strict highway weight-limit fines.
Heavy-Duty Lateral Width Extenders: Equipped with heavy swing-out outrigger brackets on both sides of the main frame. This allows the working cargo platform width to rapidly expand from 3.0 meters to 3.5 meters, making it easy to safely haul wider construction units like large excavators and agricultural harvesters.
Ultra-Low Stability Drop Deck: The dropped cargo bed design keeps the machine's weight centered close to the road surface. This geometry minimizes the risk of roll-overs during high-speed highway tracking and provides the vertical clearance needed to clear low overpasses.
Premium WABCO Pneumatic Braking: Outfitted with an original WABCO relay valve system and responsive dual-line air brakes. This ensures that even when hauling a maximum 100-ton load down steep mountain declines, the trailer reacts with instant, reliable stopping power.
Product Details
The 4 axle lowbed trailer with mechanical spring ramps stands as a premier transport asset specifically engineered to conquer the challenges of moving high-tonnage construction machinery, mining equipment, and oversized industrial payloads. Configured with a robust 4-axle tandem suspension grid, this heavy-duty lowboy trailer offers exceptional weight distribution that effortlessly satisfies strict regional axle-load safety regulations. The defining feature of this model is its dual heavy-duty mechanical spring-assisted loading ramps at the rear. These engineered ramps provide an ultra-stable, slip-resistant incline matrix that allows heavy crawler excavators, steel-wheeled rollers, and massive bulldozers to climb onto the drop-deck platform without structural swaying or flexing. By keeping the main cargo deck close to the ground, it significantly lowers the vehicle's center of gravity, ensuring unmatched tracking stability and vertical overhead clearance on long-haul highway corridors.

Features of 4 axle lowboy trailer
Application
4 axle lowboy semi trailers are suitable for short-distance relocation and long-distance transportation of construction machinery and large equipment such as excavators, loaders, road rollers, pavers, harvesters, transformers, and generator sets. The lowboy trailers are widely used in construction sites, mines, logistics parks, ports, and other scenarios, and can adapt to complex road conditions in various regions worldwide.
Packaging and Transportation
By container shipment: 40HQ can load 2 units 40ft flatbed trailer with a cut of the tail of the trailer. We have a special blueprint of this transportation way. We will design the end of the trailer to be self-mounting. It is easy to assemble it by yourself.
By bulk shipment: The most common way to transport trailers. Usually, this way is the cheapest way, and it can protect the completeness of the trailer. We will wax the surface before shipping.
By ro-ro shipment: It can protect the completeness of the trailer, and it is very time-sensitive. The tractor truck pulls the trailer into the cabin so that it can avoid the trailer from getting rusty.
FAQ
Q: What is the maximum tonnage this 2 axle lowboy semi trailer can carry?
A: The standard design load capacity is around 30 tons. Customization and reinforcement can be made based on the weight of your transported equipment, local regulations, and road conditions to ensure safe load-bearing capacity.
Q: Do you support customization of size, color, and logo?
A: Customization is supported. Flatbed length, width, ground clearance, color, markings, steel plate thickness, axle brand, etc., can be adjusted according to requirements to meet different markets and usage scenarios.
Q: What is the typical delivery time? Do you support small batch orders?
A: Delivery time for standard models is 15-30 days. Minimum order is 1 unit. Small batches and urgent orders can be prioritized for production to meet customers' needs for quick delivery.
Q: Can you match left-hand drive/right-hand drive? Do you support different national regulations?
A: The semi-trailer itself does not have a steering system, so it can be matched with various left-hand drive and right-hand drive tractors. Size, braking, lighting, and other configurations can be adjusted according to the regulations of the target country.
Q: Are you a factory or a trading company?
A: We are a physical manufacturer, producing and selling directly without middlemen. We conduct strict quality control from raw materials to finished products, ensuring stable quality while providing more competitive factory prices.
