Weichai's New Electric Transmission Mining Truck Power Solutions for 120-400 Ton Class
On November 26, the bauma CHINA 2024 was hold at the Shanghai New International Expo Center. Shandong Heavy Industry Group, featuring its two prominent construction machinery brands—Shantui and Lemot—and its global leader in power systems, Weichai, made a collective appearance at the exhibition.
At the exhibition, Weichai, alongside subsidiaries FAST and Zhuzhou Gear, showcased a wide range of power solutions for construction machinery. Their electric transmission mining truck power system features an engine-driven generator supplying direct electrical power to wheel motors, adaptable to complex road conditions. The system boasts robust thermal management, a modular design reducing maintenance costs, a major overhaul cycle of 20,000-30,000 hours, 8-12% lower fuel consumption than competitors, and improved vibration and noise performance.
Weichai showcased a diverse matrix of power solutions, including:
- WP3.6N hydraulic powertrain for wheeled excavators
- WP4.6N engine for excavators
- WP14T hydraulic powertrain for excavators
- 8M33 engine for excavators
- WP10.5H/10H engine for loaders
- WP15H engine for mining trucks
- 16M33 power unit for mining trucks
- Power packs for new energy loaders
- WP14T engine for mining trucks + new energy motor + battery
- Batteries for new energy forklifts
FAST, a subsidiary of Weichai, exhibited six products, including a three-speed pure electric transmission for mining trucks + retarder for mining trucks, a power-shift transmission for off-road tire cranes, and an AT automatic transmission. Among these, three are pure electric products, showcasing FAST's strong capabilities in autonomous forward development and deep technical accumulation.
Zhuzhou Gear brought forward several key products, such as the electric rotation system + electric pump drive system for new energy excavators, the electric transmission for new energy loaders, and the electric AMT transmission for new energy mining trucks. These products highlight Zhuzhou Gear's leadership in the highly integrated, modular, and lightweight trends of new energy construction machinery drive systems.
