Various semi-trailers and matching transport spare parts satisfy diverse heavy haul demands for global logistics businesses. Fuel tank structures adopt carbon steel material with separable inner compartments, supporting multi-oil simultaneous delivery and flexible 2/3/4 axle layout options. Pneumatic dry bulk tanks with V or W shaped bodies realize fast discharge and low residue rate for cement, fly ash and mineral powder. Ultra-low deck hauling equipment uses high tensile steel beams to carry oversized mining machinery up to 100 tons, paired with detachable goosenecks and hydraulic ramps. Rear tipping transport units equip stable hydraulic lifting frameworks to handle ore, sand and gravel in mines and construction zones. Mechanical leaf spring suspension and air spring bags balance load distribution, cut tire loss and absorb vibration on rugged roads. All transport hardware complies with international export standards, allowing customized volume, axle number and anti-corrosion treatment to fit fleets operating in Africa, Southeast Asia and Middle East.
