Easy maintenance and low cost of use: The equipped maintenance free sealed motor has a protection level of up to IP54, and can operate stably in dusty and humid environments without bearing maintenance costs for components such as carbon brushes and relays. And the overall structure is relatively simple, with fewer components than internal combustion forklifts, resulting in a lower probability of failure. Daily maintenance only needs to focus on the battery status; In addition, the cost of electricity is much lower than that of fuel, and long-term use can significantly save the comprehensive expenses of energy consumption and maintenance for enterprises.
