Pure electric port container tractor
Pure electric port container tractor
In order to implement a series of environmental protection concepts such as the "Blue Ribbon Battle" ("Two Bodies"), "Belt and Road", "To make Jinshanyinshan more green and green" and "Green Port (G20 Summit)", green environmental protection has become At present, the trend of economic and social development, our company developed a port pure electric container bow car practice green development path, which not only has good social benefits, but also significant economic benefits.
Economic and social benefits
- Low operating costs, energy costs tram 40% -60% above
- Low maintenance costs, maintenance costs Tram 40% -60% for trucks, and low failure rate
- Low operating noise, zero emission, environmental protection, and effectively improve the port operating environment
- Car body operation is simple, the original driver can adapt quickly, low-speed torque, smooth start, no delay, high efficiency
- Power system structure is simple, high reliability
