Product Overview


Specializing in the engineering and production of specialized transport solutions, our manufacturing facility delivers high-capacity Heavy Haul Double Drop Trailers. These trailers, often referred to as lowboy or lowbed trailers, feature a distinctive double-drop design characterized by a significantly lowered deck height achieved through goosenecks at both ends and a depressed center section. This design is essential for transporting oversized, heavy equipment where maximum stability and minimal overall height are critical operational requirements. Common applications include construction machinery, industrial components, and prefabricated structures where standard trailers lack sufficient clearance or load capacity.

Key Features


Robust Low-Profile Construction: Fabricated using high-strength, low-alloy (HSLA) steel grades to ensure structural integrity while maintaining the lowest possible deck height for clearance under bridges and overpasses.

Engineered Deck Configurations: Offers options for fixed, extendable, or removable decks, often featuring flush-mounted stake pockets and numerous tie-down points for versatile and secure cargo anchoring.

Optimized Axle Systems: Incorporates multiple heavy-duty axle groups (typically 2 to 5+ axles) with advanced suspension systems (mechanical, air ride, or hydraulic) designed to distribute extreme weights effectively and comply with regional road weight regulations.

Hydraulic Gooseneck Adjustment: Many models feature hydraulically operated gooseneck height adjustment, facilitating easier loading and unloading of equipment with minimal ground clearance.

Integrated Ramps & Accessories: Often includes heavy-duty, stowable ramps, side extensions, and specialized accessories tailored for specific load types, enhancing loading efficiency and safety.



Distinct Advantages


Superior Load Stability: The low center of gravity inherent in the double-drop design significantly enhances stability during transit, reducing the risk of load shifting, particularly crucial for top-heavy equipment.

Maximized Vertical Clearance: The depressed center section provides essential clearance for tall cargo, enabling the transport of equipment that would be impossible to move on standard flatbeds or step-deck trailers.

Exceptional Payload Capacity: Engineered specifically for extreme weights, these trailers handle payloads ranging from 40 tons to well over 100 tons, depending on axle configuration and regional legal limits.

Enhanced Maneuverability: Despite their size, careful design of the gooseneck and articulation points contributes to predictable handling characteristics relative to the payload size.

Durability & Longevity: Constructed with premium materials and subjected to rigorous quality control, our trailers are built to withstand demanding conditions, ensuring extended service life and reduced total cost of ownership.


FAQ


What types of cargo are best suited for a Double Drop Trailer?

Double Drop Trailers excel at transporting tall and heavy machinery like excavators, bulldozers, cranes, transformers, large generators, industrial boilers, and prefabricated building sections where height clearance is a major constraint.

How is the deck height determined?

Deck height varies based on the specific trailer design and configuration but typically ranges from 18 to 36 inches (45-90 cm) at the lowest point (center section), significantly lower than standard flatbeds. Exact specifications are provided per model.

Can these trailers be customized?

Yes, extensive customization is a hallmark of our service. Options include specific axle configurations, specialized deck surfaces (e.g., diamond plate, wood), hydraulic systems, lighting packages, brake systems, and unique tie-down solutions tailored to customer requirements.

What suspension types are available?

We offer various suspensions, including robust mechanical leaf spring, smoother air ride for cargo protection, and specialized heavy-duty hydraulic systems, selected based on payload requirements, terrain, and desired ride quality.

What certifications do your trailers hold?

Our manufacturing process adheres to international quality standards (ISO), and trailers are built to comply with relevant regional safety and transportation regulations (e.g., DOT, ADR, GVWR standards). Specific certifications are available upon request.
