Recently, a batch of heavy-duty extendable 6-axle lowbed semi-trailers independently manufactured by LUYI AUTO finished loading and departed for Mongolia, specially customized for local large open-pit mining equipment transportation demands. Mongolia boasts abundant mineral resources, yet most mine access roads are rough, uneven and narrow, with frequent long-distance cross-regional haulage of oversized mining machinery including large excavators, rock crushers, drilling rigs and heavy bulldozers. Standard flatbed trailers fail to fit such ultra-long, high-weight cargo, which pushed local mining contractors to select LUYI AUTO's tailor-made extendable lowbed solution.
This 6-axle model adopts Q345B high-tensile steel for the whole chassis, with thickened reinforced main beams to resist bending and torsion under full loads, supporting a maximum payload of 80 tons. Its core telescopic deck can stretch 4–6 meters hydraulically, easily accommodating extra-long mining devices, while multi-position mechanical lock pins guarantee rigid fixation after extension to eliminate shaking during bumpy mountain transit. Equipped with six heavy-load
FUWA axles and robust mechanical suspension, it evenly disperses ground pressure and greatly improves driving stability on rugged, unpaved mine roads. The integrated spring-loaded climbing ramps simplify loading and unloading heavy machinery without extra lifting gear.
Considering Mongolia's harsh climate with drastic temperature swings and dusty mining environments, LUYI AUTO applied anti-rust sandblasting and thick industrial paint on all steel components, plus sealed brake and hydraulic systems to avoid frost and dust damage. All key parts follow international haulage standards and match Mongolia's local road weight limits perfectly.
As a trusted Chinese trailer exporter, LUYI AUTO provides full after-sales technical guidance and spare parts supply for this Mongolian mining fleet. This delivery marks another solid cooperation milestone, proving LUYI's reliable heavy-haul equipment can fully adapt to complicated cross-border mining logistics across Central Asia.
