Construction Wheel Loader

2. Superior Power Performance and High Energy Efficiency

Equipped with a 170kW electronically controlled high-pressure common rail engine that complies with China Stage III and Stage IV emission standards, the loader meets national environmental protection construction requirements in all regions. Boasting sufficient torque reserve and excellent low-speed torque performance, the engine delivers continuous and stable power output with rapid response and no lag under severe working conditions such as heavy-load starting, thick material cutting and full-load shoveling, easily coping with various high-intensity operations.

The power transmission system adopts an exclusive customized matching solution, equipped with a dedicated electronic control transmission and a high-precision planetary hydraulic torque converter, forming an integrated and efficient closed-loop system for power output and transmission. The entire transmission system can automatically adjust the power output ratio according to real-time operating loads to achieve accurate power matching, minimize power loss, greatly improve overall transmission efficiency and maximize power utilization while eliminating ineffective energy consumption.

The loader supports three intelligent power modes including light-load, medium-load and heavy-load modes, which can be freely switched according to different construction scenarios. The light-load mode is applicable for site leveling and light material transportation to reduce energy consumption; the medium-load mode balances operating efficiency and fuel consumption for conventional stacking and handling work; the heavy-load mode provides strong explosive power for heavy-load shoveling, hard soil excavation and bulk material loading and unloading. Meanwhile, the vehicle ECU electronic control system precisely regulates fuel injection quantity, timing and pressure in real time to refine the combustion process. Compared with traditional loaders of the same class, it reduces comprehensive fuel consumption by 10%–15%, delivering remarkable economic benefits and greatly cutting long-term fuel operating costs.

To solve the industry pain points of overheating failure during long-hour continuous operation under high temperatures, the loader is fitted with an enlarged integrated heat dissipation system with a significantly increased heat dissipation area and an optimized ventilation duct designed via fluid simulation for higher heat dissipation efficiency. Even under harsh conditions such as high-temperature summer weather, all-weather non-stop construction and dense dust environments, the water temperature and oil temperature remain within the standard operating range, effectively avoiding high-temperature shutdown, power attenuation and component overheating damage and ensuring all-weather stable operation.

3. Excellent Heavy-load Stability and Durable Structure

Adopting an industry-preferred equal and long wheelbase design with an optimal wheelbase of 3200mm, the loader fundamentally enhances operational stability. It maintains balanced center of gravity and anti-roll performance under full-load heavy operation, unilateral stress and slope working conditions. Meanwhile, the optimized steering structure effectively reduces the turning radius and improves flexibility. It is competent for large-scale operations in open sites and adapts to limited construction scenarios in narrow mining areas, material yards and factory buildings with strong site adaptability.

With an operating weight of 17–18 tons and a rated load of 5.5 tons, the loader features a scientific load distribution and stable heavy-load bearing capacity. It is equipped with a standard 3.0m³ optimized engineering bucket with a bionic wear-resistant curved surface. The bucket radian and cutting edge angle are optimized through thousands of working condition tests, achieving a high material filling rate and low cutting resistance when shoveling sand, gravel, coal, ore, steel slag and other materials. It increases the single loading capacity, reduces round-trip operating times and significantly improves overall construction progress and working efficiency.

All core structural components are optimized through professional finite element analysis to solve key problems such as stress concentration, frequent wear and repeated stress under long-term heavy-load operation. The frame, boom, rocker arm and other key stress-bearing parts are made of thickened high-strength steel with reinforced welding points and stress nodes to disperse operating stress and prevent deformation, cracking and wear caused by long-term high-intensity operation. The heavy-duty reinforced articulated frame features excellent torsion resistance, bending resistance and impact resistance, tolerating long-term high-frequency impact work and greatly extending the service life of the equipment.

The walking system is fully upgraded for heavy-duty working conditions. The reinforced heavy-load drive axle adopts upgraded materials and optimized structure for internal core components such as gears and bearings, with comprehensively improved bearing capacity, impact resistance and wear resistance to output stable and strong traction force. Matched with thickened large-size wear-resistant heavy-duty tires with optimized deep tread patterns, the loader delivers stronger ground gripping performance and higher durability. It can adapt to various harsh road conditions including muddy roads, gravel roads and uneven hard mining surfaces, effectively reducing slipping and trapping risks, ensuring continuous and stable operation in complex road conditions and lowering failure rates of the walking system.
