Luyi Vehicle is an experienced semi trailer supplier & truck manufacturer which provides customized solutions.

Transporting high-density aggregates and sand requires high payload capacity under full load without penalizing fleet fuel economy on empty return journeys. This 10m 4-axle rear-tipping semi-trailer features an engineered hybrid suspension setup: the first axle utilizes air suspension with an automated lift function, allowing drivers to raise it during empty return runs to slash highway rolling resistance, toll rates, and tire wear. The rear three axles rely on heavy-duty multi-leaf mechanical suspension to absorb shovel-loading impacts and maintain rigid ground contact during steep tipping cycles.

An integrated motorized electric tarpaulin cover deploys and retracts smoothly along reinforced top rails via cab-mounted controls, sealing bulk cargo against transit spillage and environmental moisture in seconds. Paired with a heavy-duty front telescopic hydraulic cylinder and a 1.7m-deep wear-resistant U-shaped cargo body, it ensures rapid, residue-free discharge. Built factory direct at

Transporting heavy dry bulk across cross-border Central Asian corridors requires specialized climatic protection combined with high-efficiency running gear. This 50-cubic-meter Central Asia-style bulk powder semi-trailer features an advanced 6-axle full air suspension system with full-lift capability, allowing independent lifting of both the front two axles and the rear two axles during empty return legs to substantially reduce toll costs, rolling resistance, and tire wear.

The front operating deck integrates a heavy-duty protective canopy engineered for extreme temperature swings and blowing sand, shielding the industrial Changxing 4105 diesel engine and Bohai 12m³ twin-cylinder air compressor during high-pressure silo discharge. Outfitted with 385/65R22.5 wide-base super single tires, the streamlined 50m³ fluidized pressure vessel delivers fast, uniform pneumatic unloading with minimal residue for cement, lime, and mineral powders. Built factory direct at LUYI Vehicle.

This 50-cubic-meter bulk powder tanker semi-trailer features an advanced 6-axle full air suspension system with an integrated multi-axle lifting architecture: the first two axles and the rearmost axle lift independently during unladen return trips, converting the running gear from a six-axle platform into an economical tri-axle footprint that cuts highway tolls, rolling resistance, and tire wear.

Equipped with 385/65R22.5 wide-base super single tires mounted on polished aluminum alloy rims, the chassis substantially reduces tare weight while delivering superior rolling efficiency and directional tracking. The aerodynamically contoured 50m³ pressure vessel optimizes internal fluidization geometry, ensuring rapid pneumatic discharge and minimal powder residue for cement, fly ash, and dry mineral powders.

Pneumatic unloading operates independently of the tractor unit, powered by an onboard Changxing 4105 diesel engine coupled to a Bohai 12m³ twin-cylinder rotary air compressor that main

This 56-cubic-meter bulk cement tanker semi-trailer features an effective 56m³ fluidized pressure vessel, maximizing legal payload per trip for cement, fly ash, and dry industrial powders. Powered by an onboard Changxing 4105 turbocharged diesel engine and a high-output 14m³ Bohai twin-cylinder air compressor, it delivers high-volume pneumatic unloading and minimal tank residue without relying on tractor PTO power.

Built for demanding regional haulage routes, the chassis features a 3-axle reinforced mechanical leaf spring suspension paired with heavy-duty 1200R24 tube tires, providing ample axle clearance, superior sidewall puncture resistance, and dependable structural stability across unpaved quarry access roads. An integrated 500-liter auxiliary water tank supports routine line flushing and jobsite washdowns. Built factory direct at LUYI Vehicle.

Transporting multiple petroleum grades across demanding regional corridors requires specialized compartment engineering paired with robust running gear. This 38-cubic-meter French-style split-tank semi-trailer features four independent compartments, allowing fleet operators to distribute gasoline, diesel, and kerosene simultaneously in a single haul without cross-contamination.

The segmented French-style tank geometry lowers the vehicle's fluid center of gravity and incorporates reinforced transverse baffles, ensuring smooth surge dampening and superior tracking stability across high-camber curves. Fitted with heavy-duty 13R22.5 tires and a 3-axle reinforced mechanical leaf spring suspension, the chassis delivers exceptional ground clearance, puncture resistance, and dependable structural durability across rough unpaved access tracks.

Transporting oversized construction machinery and extended industrial structures demands both superior deck length and stable weight distribution. This 17.5m x 3m 3-axle low-bed semi-trailer features an expansive ultra-wide drop deck that easily accommodates large excavators, bulldozers, and steel precast components without requiring additional outriggers.

The low-profile deck geometry lowers the cargo center of gravity, significantly improving driving stability around corners while safely clearing overhead bridges. Heavy-duty spring-assisted mechanical loading ramps ensure smooth, dependable drive-on access for tracked and wheeled equipment. Supported by a rugged 3-axle mechanical leaf spring suspension, it delivers proven durability and low maintenance on demanding job site access roads. Built factory direct at LUYI Vehicle.

This 40-cubic-meter bulk cement tanker semi-trailer features an advanced full air suspension system with an integrated triple-lift configuration: the 1st, 2nd, and 5th axles lift effortlessly during empty return runs, reducing highway rolling resistance, toll fees, and tire wear.

Equipped with 385/65R22.5 super single tires on polished aluminum alloy rims, the chassis substantially reduces tare weight while improving rolling efficiency. The full-vehicle lifting system allows drivers to adjust overall chassis height on demand, providing optimal ground clearance across uneven batching plant ramps.

The aerodynamic 40m³ fluidization vessel ensures rapid pneumatic unloading with minimal powder residue, powered by an independent front-mounted diesel engine and air compressor unit.

Loading heavy tracked excavators and wheeled machinery with varying track widths often causes alignment challenges on fixed rear ramps. This 17m x 3.4m 4-axle low-bed semi-trailer solves that operational bottleneck with an advanced two-section hydraulic ramp system equipped with integrated hydraulic lateral shifting. Operators can hydraulically slide the ramps inward or outward to match the exact wheel or track gauge of diverse equipment, eliminating dangerous edge-loading conditions and manual pry-bar repositioning on job sites.

The two-section folding geometry significantly lengthens the ramp span, creating a much gentler climb angle that prevents low-clearance equipment undercarriages from scraping during ascent. With an expansive 3.4m ultra-wide cargo deck, it effortlessly accommodates large crawler cranes, bulldozers, and wide-stance construction plant without requiring separate outrigger setup.

Four heavy-duty axles supported by reinforced multi-leaf mechanical suspension deliv

Empty running on high-capacity five-axle tippers burns unnecessary fuel and scrubs expensive tires when all axles remain grounded. This 11.6m 5-axle rear-dump semi-trailer features an advanced full air suspension architecture with an integrated triple-lift system: the 1st, 2nd, and 5th axles lift simultaneously during empty return legs, converting the running gear into an agile tandem-axle footprint that cuts rolling resistance, tolls, and tire wear. Fitted with 385/65R22.5 super single tires, a 1.6m-deep reinforced cargo box, and an automated top tarpaulin system, it delivers high-volume payload capacity with market-leading operating economy.

Operating independent diesel hydraulic systems on remote job sites exposes valuable power equipment to unauthorized tampering, harsh dust storms, and component theft. This 16m 120-ton detachable gooseneck (RGN) low-bed semi-trailer features a custom-engineered heavy-duty anti-theft enclosure that fully encases the neck-mounted diesel power station and hydraulic control manifolds behind lockable reinforced steel doors. Built on four 20-ton heavy-duty axles with robust mechanical leaf-spring suspension and front/rear dual loading ramps, the 3m-wide platform handles massive crawler cranes and mining rigs with uncompromising asset security.
