In complex construction site environments, choosing the wrong construction site off-road forklift may lead to halved efficiency and soaring maintenance costs. As engineering equipment experts, we break down 4 core parameters to help you accurately match your needs — especially the off-road performance that determines success or failure.
I. Key parameter analysis: "Survival indicators" of construction site off-road forklift
Maximum load and lifting height
Load: Light-duty (3-5 tons) is suitable for bulk cargo turnover; heavy-duty (15-25 tons) is suitable for steel/prefabricated parts;
Lifting height: 3 meters meets stacking needs; 6 meters is suitable for high-rise building material transfer.
Demand matching suggestion: Daily handling of 50 tons + stacking height above 3 meters → choose a 5-ton + 3.6-meter lifting construction site off-road forklift.
Tire type: Solid tire vs pneumatic tire
Pneumatic off-road tires (such as 350×100mm wide-base tires): Improve grip by 30% on muddy/icy surfaces, anti-slip and anti-puncture;
Solid tires: Only recommended for construction site off-road forklifts operating for short periods on hardened roads.
Power system: Diesel dominance vs electric rising star
Diesel engine (Yunnei/Quanchai engine): 55-66kW power, climbing >20%, adapting to -20℃ severe cold (Hengwang HWC-35 construction site off-road forklift);
Electric: Adopting 48V permanent magnet brushless motor, zero emissions and low noise, suitable for construction site off-road forklifts in construction sites with strict environmental controls.
Ground clearance + approach angle: The off-road lifeline of construction site off-road forklift
Minimum ground clearance <300mm is prone to bottoming! Prefer 330-350mm (heavy-duty forklift standard), approach angle ≥25° ensures steep slope passability.
II. Why do 90% of buyers ignore the "transmission system"?
Hydrostatic transmission (such as Hengwang HWC-35 construction site off-road forklift) adopts a closed loop of variable displacement pump + variable displacement motor, achieving three advantages:
lConstant traction on ramps, 0 waste of diesel engine power;
lStable pressure during composite operations, speed loss <5%;
lSimplified heat dissipation structure, maintenance cost of construction site off-road forklift reduced by 25%.
Industry warning: Low-priced models mostly use mechanical transmission, and the maintenance cost of construction site off-road forklift under long-term heavy-load working conditions exceeds 30% of the purchase price!
