DuraMac Hydrogen Fuel Truck EQ4251GTFCEV
The Zhizhi EQ4251GTFCEV fuel cell semi-trailer tractor was designed by Huang Bo, an engineer at the technology center. The project originated from the actual needs of Shanxi Pengfei Group. Independent design and development began in May 2024, and the first batch of products was delivered to customers in December. It is suitable for operational scenarios such as ports, logistics trunk lines, and coal mine transportation.
As part of SinoMac, DuraMac provides a complete powertrain integrated with DCEC engine, SinoTruk engine, Fast-Eaton clutch, FAST-CAT transmission, Dongfeng-DANA axle and Komman air suspension. While the electrification of automobiles is the certain future, DuraMac also gets involved with EV powertrain systems.
We provide full life cycle services for all customers, from design to power system supply, from installation to commissioning, from after-sales service training to spare parts supply, from trouble shooting to overhaul technical support.
Advantages of EQ4251GTFCEV
-
The hydrogen fuel cell system, serving as an energy source, is equipped with multiple hydrogen cylinders and boasts advantages such as long driving range and short refueling time. Its long-distance driving range and power performance meet market operation demands, achieving hydrogen consumption of less than 0.12 kg/km on flat roads and less than 0.15 kg/km on economically feasible combined roads (fully loaded 49T), placing it in a leading position compared to its competitors.
-
The power battery utilizes Tianjin Mengguli power-type batteries, with over 50% of their products listed in domestic announcements, ensuring continuous high-power operation on mountainous roads.
-
All electrical connectors in the vehicle employ top-tier domestic or imported components to guarantee sealing and waterproofing at the connector ends, enhancing the high reliability and safety of electrical components.
