FAQ
Q1: Is the HOWO pure-electric single-side dock tractor an original-factory export-qualified unit?
It is original-factory export-qualified enclosed dock-yard only pure-electric tractor. Fifth-wheel is optional. This unit has no on-road motor-vehicle homologation, NOT licensed for public-road driving, only permitted inside enclosed port / factory premises. Manufactured to overseas industrial-equipment standards, no non-standard refit, complying with general overseas industrial-site safety requirements.
Q2: Are spare-parts universal among different battery-capacity variants?
All variants share identical chassis, axle, brake, cab and running-gear parts. Only battery pack and BMS parameters change with capacity options. Spare-parts are well-supported in overseas market.
Q3: Does it support customization and which markets does it suit?
Original-factory LHD/RHD customization available; customizable battery-capacity(282kWh /354kWh), fifth-wheel specification, tire pattern and body-color. LHD mainly suits Africa, Central Asia, Middle East and South America; RHD version available for Southeast-Asia. For Australian projects: customer shall complete additional local industrial-equipment certification; factory basic certification does not cover full Australian regulatory compliance.
Q4: How to select battery-capacity and charging-solution?
282 kWh standard version for medium-intensity shift-work in yard; 354 kWh large-capacity for long-duration continuous-operation. DC fast-charge is supported; site-side industrial DC charger with matching voltage-rating shall be prepared by customer. LFP battery features good temperature-resistance for heavy-load yard-working cycles.
Q5: What yard-working scenarios is this unit suitable for?
25 km/h top speed is safety-oriented for port-yard, not designed for high-speed driving. Suitable for towing yard container semi-trailers and flat-bed trailers. Max 38 t towing GCW is reference value for flat enclosed yard condition. Reduce speed under heavy-load climbing; keep ground dry to avoid slip. Not permitted for highway / public-road use.
Q6: What are core advantages of this yard tractor?
Zero-emission pure-electric power with low operating noise. IP67-protected LFP high-voltage battery set with complete high-voltage safety-protection measures. High-power permanent-magnet synchronous motor (140 kW rated / 260 kW peak), delivers good performance for heavy-load yard start-up and climbing. Regenerative brake for energy-saving. Single-side-optimized cab for frequent yard shunting & reversing. Multiple battery-capacity OEM custom options. Mature overseas spare-part supply channels. Well-suited for container and flat-bed trailer-towing in overseas ports and large enclosed industrial-sites.
