Q1: Is this 3-axle rear-tipping dump semi-trailer an original-factory export model?<\/h4>\n

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.<\/p>\n

Q2: Are spare-parts universal among different configurations?<\/h4>\n

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.<\/p>\n

Q3: Does it support customization and which markets does it adapt to?<\/h4>\n

Customizable items: king-pin specification, cargo-box volume(16-26m\u00b3), 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.<\/p>\n

Q4: What requirement for tractor-head for tipping operation?<\/h4>\n

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.<\/p>\n

Q5: What working-conditions for each cargo-box volume option?<\/h4>\n

16-18m\u00b3 for high-density ore to avoid over-loading; 20-22m\u00b3 as highway standard for medium-density sand-stone & earth-rock; 24-26m\u00b3 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.<\/p>\n

Q6: What are core advantages of this semi-trailer?<\/h4>\n

U-shape NM450 high-strength wear-resistant cargo-box; heavy-mining-oriented reinforced 500\u202fmm 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.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
