Key Features and Applications
High-Tensile Welded Chassis Beam
The chassis main beams are fabricated from Q345B/Q460C high-tensile steel using automated submerged arc welding. The deep I-beam configuration resists bending, sagging, and torsional twisting under heavy payloads across rough highway and port haul routes.
Multi-Configuration Container Locks
Fitted with 12 sets of heavy-duty retractable ISO container twist locks, the trailer enables flexible multimodal loading configurations: one 40ft container, two 20ft containers, or one centered 20ft heavy container. The locks retract flush into the deck when transporting breakbulk cargo.
Heavy-Duty Running Gear and Axles
Configured with tri-axle (3-axle), 2-axle, or multi-axle setups using proven FUWA or BPW axles. Suspensions can be specified as heavy-duty mechanical leaf spring suspensions with multi-layer leaf packs for rugged routes, or air suspension for cargo sensitive to vibration.
Non-Slip Heavy-Gauge Steel Deck
The cargo platform utilizes a 3 mm diamond-pattern checker steel plate reinforced by dense cross-members. This structure provides high point-load capacity, prevents surface deformation under heavy industrial freight, and reduces cargo slippage during transit.
Primary Logistics Applications
-
Intermodal Shipping: Port-to-warehouse drayage of ISO dry and refrigerated containers.
-
Industrial Goods: Transport of steel plates, structural beams, machinery crates, and pipes.
-
Bulk & Agricultural Freight: Hauling bagged cement, lumber, palletized goods, and agricultural products.

Dimensions and Operating Range
The standard 40ft flatbed semi trailer features overall dimensions of 12,500 mm in length, 2,500 mm in width, and a deck height of 1,530 mm. The unobstructed open platform allows for efficient top-loading via gantry cranes as well as side-loading via forklifts. Side rope hooks and tie-down winches are distributed along the outer side rails to secure oversized machinery and irregular industrial cargo.
Supplier Support
We provide technical documentation, configuration consulting, and export procurement support for CNFORCE flatbed semi trailers. Our engineering team assists with tractor truck fifth-wheel height matching, kingpin sizing, and axle count customization according to regional axle-load regulations. To protect trailers during ocean transport, units undergo shot blasting, anti-corrosion primer application, and marine-grade protective wax coating prior to RORO, bulk vessel, or containerized shipping. Spare parts, including twist locks, landing gear components, and brake valves, are accessible through our global supply network.
Frequently Asked Questions
What types of cargo can be transported on this flatbed semi trailer?
The flatbed trailer is designed to haul standard 20ft, 40ft, and 45ft ISO shipping containers, as well as general breakbulk cargo including steel plates, structural coils, lumber, crated equipment, and bagged materials.
How many container configurations can the twist locks accommodate?
Equipped with 12 sets of retractable twist locks, the trailer can carry one 40ft container, two 20ft containers simultaneously, or a single 20ft container positioned in the center for balanced weight distribution.
Can the trailer dimensions and axle counts be customized?
Yes. Depending on local transport regulations and payload requirements, the trailer length (20ft, 40ft, 45ft, 48ft, or 53ft), width, and axle count (2-axle, 3-axle, or 4-axle with front lift axle) can be tailored to client specifications.
How are the trailers protected against corrosion during ocean shipping?
All chassis components undergo surface shot blasting to remove scale and rust, followed by zinc-rich anti-corrosion primer and polyurethane topcoats. Before maritime loading, exposed metal surfaces receive protective wax spraying to resist saltwater atmospheric corrosion during transit.
