In order to meet the needs of the operation, the pure electric container forklift was modified, and the heating air in the cab was electric after the modification. With the increasingly busy port operations, electric heaters need to work for a long time, sometimes even 24 hours a day, and long-term overload operation can easily cause the electrical circuit to generate heat, which can easily lead to safety accidents such as fire or electric shock, bringing serious safety hazards to on-site operations.
