Heavy Duty 3 Axles 40ft Lowboy Semi Trailer

This heavy-duty 3-axle 40ft lowboy semi trailer (SCD9402TDP) carries 50-60 tons on a 500 mm main beam (upper 16 mm, lower 18 mm, middle 10 mm) with three FUWA 13-ton axles and 10/10/10 leaf springs. The gooseneck design drops the 3 mm checkered deck to 1,650 mm for hauling tall excavators and bulldozers under bridges and power lines. 13,000 x 3,000 x 1,650 mm, 11.00R20 radial tyres, 28-ton dual-speed landing gear, dual-line pneumatic brakes. One-year warranty, MOQ 1 unit.

Gooseneck Deck at 1,650 mm - Clears Overhead Obstacles

The 40ft lowboy semi trailer's gooseneck front end and low platform height keep the loaded machine low enough to pass under standard highway overpasses and overhead utility cables, and the lower centre of gravity improves stability and safety compared to a flatbed when hauling tracked excavators. The steel comes from large-mill sources to guarantee the main beam's tensile strength.

500 mm Beam with 16/18/10 mm Plates

The main beam on this lowboy uses a 500 mm web with a 16 mm upper plate, 18 mm lower plate, and 10 mm middle web - thicker than standard trailer beams because a tracked machine concentrates its weight on a small deck footprint. All welding is done by certified, experienced workers, and every trailer receives sandblasting, anti-rust primer, and a polyurethane topcoat.

One-Year Warranty, Free Replacement Parts

Every lowboy semi trailer comes with a one-year warranty. If any accessory is damaged under normal use during that period, we supply new parts free of charge. Ongoing technical support and genuine spare parts keep the trailer working beyond the warranty window. MOQ is 1 unit, so you can evaluate a single lowboy before committing to a fleet order.

20+ Years of Trailer Production, Factory Visits Welcome

Our own factory has 17 years of trailer production experience plus a truck conversion facility, and we also supply a wide range of international-brand earthmoving machinery. Factory visits are welcome - inspect the welding quality, test-fit your equipment on the deck, and see the polyurethane finish before your lowboy leaves the production line.
