What makes this low bed trailer different

Shipping to Russia: what to check before you order

Russia-bound trailers are usually specified around three constraints: permitted dimensions, permitted axle loads and the type-approval documents. Here is how this trailer is matched to them.

1. Dimensions. Russian rules allow a road train of up to 20 m in length, 2.55 m in width and 4 m in height without a special permit; above that, a permit for heavy or oversize movement is required. A 2,550 mm wide trailer with a standard gooseneck keeps the empty combination inside the limit — which is why the 3,000 mm extension deck is quoted as an option, not as the default.
2. Axle loads. We space the axles and size the tyres to your tractor and your permitted axle-load figures, so the combination is engineered for the load table you have to work with rather than for a catalogue number.
3. Type approval and paperwork. Tongya Automobile obtained the OTTC Russian vehicle type approval in January 2026. Trailers placed on the Russian market fall under the Customs Union technical regulation TR CU 018/2011 “On safety of wheeled vehicles”. Ask the sales team which OTTC and technical documents apply to your exact configuration before you sign.
4. Permit drawings. When a special permit is needed, we supply dimension drawings, axle-load figures and the wheel-plan data used in the permit application.
5. Cold-climate specification. Low-temperature brake hoses and seals, and a heavier paint system for road-salt exposure, are specified for Russian routes — state your operating region when you order.

Typical applications

• Excavators and bulldozers — tracked plant driven on over the folding ramps; deck length and ramp angle matched to the machine.
• Cranes, drilling rigs and crushers — heavy, high-centre-of-gravity loads that need a low deck and wide load spreading.
• Road-building equipment — pavers, rollers and milling machines moved between sites on public roads.
• Construction modules and steel structures — long loads carried on the flat-deck variant with lashing points along the side beam.
• Municipal and port equipment — tighter yards where steering rear axles reduce scrub and turning effort.

Manufacturing, quality control and after-sales

Tongya Automobile Co., Ltd has built semi-trailers and special vehicles since 1982 and has exported since 2006. The factory covers more than 400,000 m² with 600+ staff and 1,200+ sets of equipment, producing 16,000+ units a year. More than 400 welders work the production lines, and the main beams of our low bed trailers are joined by automatic submerged-arc welding for consistent penetration.

• Main beam sizing calculated from the load and axle spacing you declare, in Q345B high-tensile steel.
• Axles, kingpin, landing gear, brake valves and lamps from named suppliers (JOST, WABCO, FUWA, BPW, SAF) so parts stay available locally.
• Pre-delivery inspection with brake, lighting and ramp function tests before the unit is loaded.
• Spare parts supply for axles, brakes, suspension, ramps and kingpin assemblies.
• Technical support in English and Russian by phone, e-mail and WhatsApp; our Russian-language site is at ru.trailerfactory.cn.
