4 Axle 45FT Flatbed Semi Trailer

The 4 Axle 45FT Flatbed Semi Trailer is HUAYU's long-deck flatbed for 45ft container haulage and heavy general cargo: a 13,700mm checkered-steel platform on four HUAYU-brand axles with 16 dual tires. Twelve retractable ISO twist locks take one 45ft, one 40ft, or two 20ft boxes. The photos show a fresh white build in the Liangshan factory yard.

• 13,700mm deck: carries one 45ft container end to end, plus overhang-length general cargo
• 4 axles, 16 dual tires: spreads 60-80T loads across four axle lines
• 12 retractable twist locks: laid out for 1x45ft, 1x40ft, or 2x20ft container sets
• 3mm checkered floor plate: anti-slip deck that takes forklift loading
• Mechanical 10-leaf suspension: no air bags to source in remote regions
• 28T two-speed landing gear: bolt-in 2 inch or 3.5 inch kingpin fits standard tractors
• Toolbox, side guard, spare tire: shipped on the trailer, ready for work

Running Gear: Four Axles, 16 Duals, 10-Leaf Springs

Four axle lines sit under the rear half of the deck, each on a 10-leaf mechanical spring stack. The close-up photos show dual 12R22.5 tires on every hub, hanger grease points between axles, and a brake chamber at each wheel end.

Sixteen contact patches share the load, so per-tire stress stays low on rough laterite and broken tarmac. Mechanical suspension stays serviceable with hand tools.

There are no air bags, height valves, or ECAS parts to wait for. A quad-axle flatbed of this deck length is the standard answer where axle-load rules cap 3-axle outfits.

Four HUAYU-brand axles with 16 dual tires carry the 13.7-meter deck of this 45ft flatbed semi trailer.

Twelve Twist Locks Set for 45ft, 40ft, and 2x20ft Boxes

Container work is where this long deck earns its keep. Twelve retractable ISO twist locks sit in the side beams: end pairs for one 45ft box, intermediate pairs for one 40ft or two 20ft containers.

Retracted, the lock heads sit below deck level, so flat cargo never snags on them. The photos also show the side-rail lashing winches used to strap non-container loads. As a container flatbed trailer, it can run box work in the morning and haul bagged cement or steel in the afternoon.

The Q345B main beam, brakes, and landing gear are shared with our 4 Axles 40FT Flatbed Container Semi Trailers, which covers that chassis in detail. This 45ft model adds 700mm of deck and the extra lock positions.

Who Runs a 45FT Flatbed

• East African container fleets: 45ft boxes and breakbulk on port-to-inland corridors in Tanzania, Zambia, and Mozambique
• West African building-material distributors: bagged cement, rebar, and block loads between city depots in Benin, Nigeria, and Ghana
• Project forwarders: crated machinery and overlength cargo that outgrows a 40ft deck
• Mixed fleets: one trailer swaps between container work and open-deck general cargo

Frequently Asked Questions

What are the dimensions of the 45ft flatbed semi trailer?

The standard build is 13,700mm long and 2,500mm wide, with a deck height of about 1,550mm at the front beam. This platform is flat from the front board to the rear beam, so the full 13.7 meters takes a 45ft container or overlength cargo. Tare weight is about 7.8 tons, and other deck lengths between 12.5 and 14 meters can be built to order.

Which shipping container sizes can it carry?

One 45ft, one 40ft, or two 20ft containers. The twelve retractable ISO twist locks are positioned for all three sets, so the open deck works as a container flatbed trailer rather than a plain platform. High-cube 45ft boxes use the same lock points. If your fleet only runs 40ft boxes, the 40ft 4-axle model in our flatbed trailer range saves tare weight.

Why four axles on a 45ft flatbed trailer?

Deck length and axle-load law. A 13.7-meter deck invites heavy, long cargo, and four axle lines keep the load per axle within the limits used on most African and Middle Eastern routes. Sixteen tires instead of twelve also cut tire stress on hot, rough roads. The longer wheelbase adds some tire scrub in tight yards, which is why a heavy-duty 45ft deck is rarely offered as a 3-axle build.

How much payload can a 4 axle flatbed trailer of this length handle?

The working rating is 60 to 80 tons, set by the axle and suspension option you choose: 13T axles suit legal-road container work, while 16T axles with the reinforced beam cover the 80-ton end. A 45ft high-cube container of general cargo rarely exceeds 30 tons, so the headroom covers steel, machinery, and dense project loads. The frame side of that math is covered in how frame design determines carrying capacity.

What is the price of the 45ft flatbed semi trailer?

The displayed $12,300 is the FOB Qingdao reference price for the standard configuration shown here. Options like air suspension, 16T axles, or a different tire size move the final figure, and sea freight is quoted per destination port as CIF or CFR. Send an inquiry with your destination and spec list for a firm quote.

What warranty comes with this 45ft flatbed?

10-year warranty on the main beam, with a 1-year warranty on the body structure and welded joints. Component warranties follow the original manufacturer's terms.

30% deposit by T/T confirms your order; the 70% balance is paid before shipment. When your trailer is finished we send photos and videos of the actual unit, so you see what you bought before paying the balance. For larger orders we accept an irrevocable L/C at sight.
