FAQ
Q1: Is this 3-axle rear-tipping dump semi-trailer an original-factory export model?
It is original-factory export-qualified 3-axle rear-tipping dump semi-trailer. Hydraulic tipping system, king-pin and landing-gear are optional. Only semi-trailer itself, tractor-head is NOT included. It is 40-ton GVW road-legal highway-compliant model. Assembled complying with overseas mine-construction standards, no domestic-market re-modification or non-standard refit, complying with global public-road vehicle access regulations.
Q2: Are spare-parts universal among different configurations?
All variants share the same main-beam frame structure. Most axle, suspension, brake and lamp parts are interchangeable. Hydraulic cylinder and landing-gear brands depend on options; spare-parts are well-supported in overseas market.
Q3: Does it support customization and which markets does it adapt to?
Customizable items: king-pin specification, cargo-box volume(16-26m³), wear-resistant steel thickness, axle brand, suspension type(mechanical/air-suspension), lift-axle, tire pattern and body-color. When matched with LHD tractor-head mainly suits Africa, Central Asia, Middle East and South America. When matched with RHD tractor-head mainly suits Southeast Asia, Australia and Commonwealth regions.
Q4: What requirement for tractor-head for tipping operation?
Tractor-head must be fitted with transmission-mounted PTO output interface to supply power for semi-trailer hydraulic system. Without PTO interface, dumping-tipping function cannot be realized.
Q5: What working-conditions for each cargo-box volume option?
16-18m³ for high-density ore to avoid over-loading; 20-22m³ as highway standard for medium-density sand-stone & earth-rock; 24-26m³ only for low-density bulk goods such as coal & wood chips. Strictly forbid over-loading heavy-density cargo by using over-sized box volume. Reinforced wear-resistant box version is recommended for heavy-duty mining application.
Q6: What are core advantages of this semi-trailer?
U-shape NM450 high-strength wear-resistant cargo-box; heavy-mining-oriented reinforced 500 mm Q700L main beam; proven HYVA rear-mounted hydraulic tipping system. ABS fitted as export-standard; optional air-suspension and lift-axle. Adopt internationally mainstream JOST brand king-pin and landing-gear. Rich OEM custom options, mature overseas spare-part supply channels with low maintenance cost. Well-suited for overseas mine, infrastructure sand-stone & earth-rock legal public-road bulk-cargo transportation.
