FAQ
Q1: Is the HOWO 6×4 trucks-mounted crane an original factory export model?
It is an officially designated export 6×4 heavy-duty 2-type chassis for trucks-mounted crane of SINOTRUK HOWO series. Crane and cargo-box belong to optional super-structure, assembled complying with overseas engineering standards. There is no domestic-market re-modification or non-standard refit, fully complying with global vehicle access regulations.
Q2: Are spare parts universal for all versions?
All versions share the same three-axle heavy-duty chassis, dual rear axles, brake and body parts. Gearbox varies for different emission versions, engine accessories differ slightly among emission sub-models. Crane and cargo-box super-structures are interchangeable for all horsepower variants, ensuring convenient global maintenance and high spare-parts popularity.
Q3: Is custom service available?
Original factory LHD/RHD customization, Euro 2 / Euro 3 / Euro 5 emission selection, crane tonnage (telescopic / knuckle-boom), cargo-box dimension and body-color customization are supported. LHD mainly suits Africa, Central Asia, Middle East and South America; RHD mainly suits Southeast Asia, Australia and Commonwealth regions.
Q4: How to choose Euro 2 / Euro 3 / Euro 5 versions?
Euro 2 mechanical injection version adapts to areas with moderate fuel quality and simpler maintenance conditions, but recommended diesel grade shall still be followed, severely off-spec fuel is prohibited. Euro 3 and Euro 5 electronic versions meet high environmental-protection requirements with fuel-saving and eco-friendly performance.
Q5: What working conditions is each horsepower version suitable for?
371HP(Euro2) for short-haul lifting & building-material transport; 400HP(Euro3/Euro5) for medium-distance construction-equipment delivery; 430HP(Euro3/Euro5) high-torque version for high-intensity construction-site operation on mountainous and steep-slope roads.
Q6: What are the core advantages of this model?
Equipped with reinforced 6×4 three-axle heavy-duty 2-type chassis, it achieves 25-ton compliant GVW and high stability. Mature six-cylinder powertrain delivers sufficient power and high operational availability, low failure rate. Factory-reserved PTO interface supports multiple-brand telescopic / knuckle-boom cranes. Multiple OEM customization options, globally-available spare-parts and low maintenance cost bring outstanding cost-performance for overseas construction-site lifting, building-material and equipment transfer work.
