On April 30, 2026, SINOTRUK Mianyang Special Vehicle Co., Ltd. received a batch of HOWO New Energy TX7 engineering dump truck chassis manufactured by China National Heavy Duty Truck Group Jinan Truck OEM. These chassis will undergo customized modifications at Mianyang Special Vehicle Co., Ltd., featuring a 5.8-meter rectangular cargo box, ultimately forming the HOWO New Energy engineering dump truck and launching it to the market, injecting new green momentum into the engineering transportation sector.   The HOWO New Energy TX7 chassis delivered this time boasts robust and reliable core configurations. It is equipped with a TZ388XS-ZQV13 (CNHTC WT330) drive motor, matched with a 300.92kWh high-capacity battery pack, ensuring stable and efficient power output. The transmission system uses an HW19705XA gearbox and an HW50 direct-drive power take-off, while the rear axle is an MCX16ZG self-adjusting boom double rear axle (drum), paired with a double-layer frame (8+4/300), balancing load-bearing capacity and driving stability, making it suitable for various engineering operation scenarios.   As a new energy engineering dump truck, its most prominent advantage is its low-carbon and environmentally friendly nature. Compared to traditional fuel-powered dump trucks, it has zero exhaust emissions, effectively reducing air pollution during engineering operations and aligning with the green transformation needs of engineering transportation under the "dual-carbon" strategy. Simultaneously, the electrified design also features low energy consumption costs and easy maintenance, helping engineering companies reduce costs, increase efficiency, and enhance operational competitiveness.   As an important special-purpose vehicle production base in Southwest China, Sinotruk Mianyang Special Vehicle Co., Ltd.'s customized development of the HOWO new energy engineering dump truck is a significant step in its deep cultivation of the special-purpose vehicle field and its strategic layout in the new energy vehicle sector. In the future, the company will continue to leverage Sinotruk's technological advantages to launch more high-quality new energy special-purpose models, contributing to the green and high-quality development of regional infrastructure and engineering transportation industries.
