What Scenarios Suit the DE26-EV Electric Bulldozer? Heavy-Duty Operations Powered by a 423.94 kWh High-Capacity Battery

Core Advantages of the DE26-EV Pure Electric Bulldozer

The powertrain of the Shanbo Heavy Industry DE26-EV pure electric bulldozer is a core electric drive assembly independently developed for a new generation of green, intelligent, and low-carbon electric crawler bulldozers. The system utilizes an advanced, high-efficiency permanent magnet synchronous motor (PMSM) drive architecture that directly replaces traditional diesel engines. It integrates seamlessly with the heavy-duty hydraulic system, balancing environmental friendliness with robust heavy-duty construction capabilities.

This equipment delivers green operation with zero emissions and ultra-low noise levels. It features excellent torque response and outstanding energy efficiency, easily handling various high-load construction conditions. The machine is equipped with a 423.94 kWh high-capacity lithium iron phosphate (LFP) battery pack (operating voltage: 614.2 V) and an intelligent Battery Management System (BMS) to ensure safe and stable operation. Its 200 kW high-power permanent magnet synchronous main motor delivers a peak torque of 200 Nm, with an overall response speed improved by over 15%. With an electric drive energy conversion efficiency exceeding 90%, the machine reduces overall energy costs by more than 60% compared to traditional diesel bulldozers, helping customers achieve better economic returns.

Comprehensive High-Voltage Safety and Intelligent Thermal Management for Continuous Heavy-Duty Operation

The DE26-EV bulldozer features a comprehensive high-voltage safety protection system. It is equipped with a 2500 Vac high-voltage insulation tester and ultra-fast (10ms-level) leakage protection; the system cuts power rapidly upon detecting any anomaly, fully ensuring the operational safety of the vehicle's electrical system. Key components—such as the High-Voltage Power Distribution Unit (PDU) and all-metal, high-strength, waterproof, and dustproof high-voltage cables and connectors—offer excellent resistance to vibration, impact, and electromagnetic interference, making them suitable for harsh construction site environments.

The machine is equipped with a complete intelligent thermal management system, integrating a 45 kW high-capacity plate-fin liquid cooling assembly, an 8 kW battery cooling unit, and an electronically controlled variable-frequency air conditioning system.

It enables precise, constant-temperature control for the main motor, motor controller, and power battery. Even in high-temperature, dusty job sites, it maintains stable operating temperatures for these core electric components, supporting prolonged, heavy-duty continuous operation.

Key Operating Scenarios for the DE26-EV Electric Bulldozer

With a high-capacity 423.94 kWh battery, a powerful 200 kW output, and a highly reliable electric powertrain system, the DE26-EV battery-electric bulldozer is primarily designed for open-pit mining operations. Capable of handling demanding tasks such as ore pushing, site leveling, and overburden removal, the motor delivers instantaneous power response and thrives in the high-intensity, continuous operating environments typical of mines—characterized by heavy dust and frequent shock loads.

Beyond open-pit mining, this electric bulldozer is ideal for industrial projects subject to strict environmental regulations. Producing zero tailpipe emissions and no diesel exhaust pollution, it is well-suited for enclosed industrial sites and "green," low-carbon demonstration projects. Its ultra-low noise operation allows for use in noise-sensitive areas, effectively minimizing the impact on the surrounding environment, making it a preferred choice for the green transformation and upgrading of construction machinery.

Modular Integrated Powertrain: Balancing Maintenance and Global Market Readiness

The DE26-EV features a highly modular, compact, and integrated 3D powertrain layout, optimizing the use of limited space within the machinery compartment. Key components—including the integrated motor controller, the electric drive and work pump module, the permanent magnet synchronous main motor, and the hydraulic pump assembly—utilize spline connections. Additionally, the high-voltage power distribution unit connects directly to the main controller, reducing the need for external high-voltage cabling and enhancing the machine's resistance to high-frequency interference.

The clear system topology ensures a rational spatial arrangement for the electric powertrain and hydraulic pump assembly, facilitating easy inspection and routine maintenance for technicians. The entire powertrain supports technical specifications in both Chinese and English, fully complying with international standards for construction machinery; this ensures it meets the needs of domestic mining and industrial projects while also satisfying demand in overseas markets for green engineering equipment.
