This 3-axle lowbed semi-trailer with hydraulic gooseneck is purpose-built for hauling excavators, bulldozers, wheel loaders, drilling rigs, transformers and other heavy or over-height machinery. Its drop-deck design keeps the load low and the center of gravity down, so tall equipment clears bridges and height limits that a flatbed cannot. The standard build carries a 60–80 tonne design payload on three 13-tonne FUWA axles shod with Linglong 315/80R22.5 tires, and the gooseneck raises and lowers hydraulically from an on-board diesel power pack — no detaching, no crane. Every unit is welded and finished by Tongya Automobile Co., Ltd. (CTAC TONGYA AUTO) in Liangshan, Shandong, one of China's largest approved trailer manufacturing bases. One unit is the minimum order, and configurations can be adapted to your road rules, tractor and cargo.

Built for Heavy Machinery and Oversized Loads

A lowbed semi-trailer earns its money on jobs where a standard flatbed fails: mining operators moving a 30-tonne hydraulic excavator between pits, quarries relocating crushers and screens, construction firms hauling piling rigs and dozers to new sites, and plant-hire fleets repositioning loaders with their booms left mounted. This model is engineered for exactly that class of work. The depressed drop deck lets you carry loads up to about 4.0–4.2 m overall height while staying inside the common 4.0–4.2 m road corridor in many markets, and the reinforced deck carries concentrated track loads from crawler equipment without oil-canning. Side lashing points and recessed tie-down rings are spaced along the deck edges so chains and binders can be rigged at practical angles for every common machine width. Because the trailer is a purpose-built low bed rather than a converted flatbed, the gooseneck, main beams and axle groups are matched from the design stage to distribute gross weight legally across three axles instead of overloading the rear

Fuwa Axles and Linglong 315/80R22.5 Tires: a Proven Running Gear

Underneath, the trailer runs on three FUWA 13-tonne bolt-on axles — the most widely stocked Chinese axle brand in the global aftermarket, which means hubs, drums, brake shoes, spindles and oil seals are available from Africa to Central Asia without special ordering. Wheels are heavy-duty six-stud steel rims matched to the Linglong 315/80R22.5 tires fitted as standard: a wide, high-load radial common on lowbed duty, offering a strong footprint, good heat behavior on loaded highway runs and easy replacement in nearly every export market. Suspension is FUWA-type mechanical bogie with graduated leaf springs, sized for the payload you specify; air suspension for sensitive cargoes or steering/liftable axle variants can be quoted as an option. Braking uses a dual-line system with WABCO-type relay valves and spring brake chambers, with ABS available where your registration authority requires it. Because every major running-gear part is a catalog item rather than a bespoke one, your maintenance team can service the trailer with locally bought components and standard workshop tools, which keeps lifetime operating cost far below what exotic brand combinations demand in remote regions.

Key Technical Specifications

The table below summarizes the standard configuration shown in the photographs. Values marked "options" are factory-adjustable; final dimensions, tare weight and weight distribution are confirmed on the drawing we issue against your machine list and tractor data before production starts, so you approve real numbers rather than brochure figures.

Options and Customization for Your Market

Export buyers rarely need the "standard" brochure unit, and this trailer is built to be specified rather than accepted. Axle capacity steps from 13 t to 16 t; tire size switches between 315/80R22.5 and 12R22.5 depending on deck height and availability in your country; and the overall length, drop-deck length and neck geometry are adjusted around your longest and tallest machine — tell us the exact excavator or dozer models you haul and the plant engineer sizes the deck, ramp angle and axle placement accordingly. Lamp packages follow either ECE or DOT conventions, reflectives match local codes, and ABS is added where registration demands it. Other common add-ons include a hydraulic pump from a different brand, spare-wheel carrier positions, extra lashing rings for coil or transformer cargoes, aluminum or timber deck surfaces, and a toolbox with the standard roadside toolkit. Left- and right-hand-drive tractor compatibility is handled through the fifth-wheel height and king-pin position declared on the order.

Manufacturing Quality You Can Verify

Tongya Automobile Co., Ltd. is an approved Chinese automobile and trailer manufacturer, not a trading shell: design, welding, shot-blasting, painting and assembly happen in our own works in Liangshan County, Jining, Shandong — the country's densest trailer-manufacturing cluster, which also means every consumable part on the trailer is procurable nearby within hours. Production follows ISO 9001 process controls, and domestic units carry CCC certification; export builds are documented for destination-market registration. The main beams are welded by trained operators on jigs, the full chassis is shot-blasted to remove mill scale before a primer coat and two finish coats, and each finished trailer passes a road-test style pre-shipment inspection covering brakes, lights, steering tracking and fastener torque. Buyers are welcome to inspect the unit in person or on a live video walkthrough before balance payment, and third-party inspection services such as SGS or Bureau Veritas are routinely hosted at the yard. You can also trace our build quality through the unit's chassis number: welding records, painting batch and inspection sheets stay archived, so any question years later can be answered with the original documents.
