Product Overview
The Q250LS is a large-tonnage heavy-duty electric tractor, equipped with an 80V large-capacity lithium-ion power system, with a rated traction load of 25 tons, and a driver's cab with a protective roof. It is specially designed for bulk material transfer in heavy industrial scenarios. The model replaces the traditional internal combustion traction scheme with electric drive, has no exhaust emissions, and has lower operating noise. It can be adapted to open-air storage yards, large factories and other open operating environments to meet the heavy-duty trailer traction needs of heavy industry manufacturing, port freight, and vehicle factories.

III. Product core advantages
1.25 tons of heavy-duty traction, suitable for large and heavy working conditions
Designed for heavy material transfer scenarios, it can drag large-tonnage container trailers, heavy-duty mold trolleys, and group tooling trailers, with a larger single transfer volume and reduced round-trip operation frequency. The power output is calibrated for heavy loads, and the power is released smoothly in the starting and climbing stages. The power performance is stable when towing heavy loads, suitable for heavy industry, ports, vehicle manufacturing and other heavy material transfer scenarios.
2.80V high-voltage lithium battery platform, stable battery life for long shifts
With 80V high-voltage electrical architecture and 560Ah large-capacity lithium battery pack, the power reserve is sufficient, which can cover the needs of single-shift or even two-shift operations. The electric drive structure does not need to be filled with fuel or oil, and has no daily exhaust emissions. The operating noise is lower than that of internal combustion tractors of the same level, which not only meets the environmental protection control requirements of the factory, but also reduces long-term fuel and maintenance expenses. The battery charging process is standardized, and the operation and maintenance are simple.
3. With roof protection cab, outdoor operation is more friendly
Equipped with an integrated protective ceiling cab, equipped with a wide-field windshield structure and rearview mirrors on both sides, the operator is seated and controlled by the steering wheel, and the working field is wide; the ceiling can be shaded from the sun and rain, and is suitable for non-closed working environments such as open-air yards and outdoor factories to improve the convenience of operation in bad weather. The interior of the cab adopts ergonomic shock-absorbing seats, which are not easy to fatigue after driving for a long time. The layout of the operation controls fits the usage habits of industrial vehicles, and the difficulty of getting started is low.
4. Heavy-duty bearing chassis, highly adaptable to working conditions
Adopting a four-wheel heavy-duty chassis structure and industrial-grade solid wear-resistant tires, it can adapt to various factory road conditions such as cement hardened pavement and gravel ground in the yard, and the bearing and impact resistance are suitable for large-tonnage traction conditions. The body counterweight is optimized, and the body posture is stable during heavy-load traction and steering. The braking system is designed to match the large-load working conditions, and the braking distance is controllable to ensure the safety of the working process.
5. Standardized industrial design, long-term operation and maintenance costs are controllable
The core electrical and transmission components adopt industrial-grade mature solutions, with strong versatility of vulnerable accessories. The daily maintenance items are less than those of internal combustion tractors, which can reduce the time for equipment shutdown and maintenance. The vehicle structure follows the safety design specifications of industrial vehicles, and is equipped with driving brakes, parking brakes and sound and light warning devices to meet the safety management requirements of factory operations.
IV. Applicable scenarios
Heavy machinery manufacturing plant, port terminal rear yard, automobile production base, large metallurgical building materials plant, airport freight hub, heavy mold and tooling transshipment, bulk cargo open yard transshipment and other large tonnage, long-distance traction operation scenarios.
