Briefly describe the winter maintenance of battery pallet trucks

In recent years, with the advancement of battery pallet truck technology, the AC drive system focusing on electric motors has the advantages of high production efficiency and high cost performance. The overall performance of the electric-hydraulic pallet truck is even higher, which meets the needs of most customers and has been recognized by users. Now that winter is coming, how do electric pallet trucks need to be maintained in winter? What do you say below?

Before you understand the common sense of maintenance, let me introduce the common sense of the AC drive of the electric motor of the battery pallet truck brand. The principle of the induction motor AC drive system of the battery pallet truck is to transmit three-phase AC power to the fixed rotor winding, and generate a torsional electric field to induce the closed rotor winding to generate current, and the rotor rotates along the dynamic direction of the rotating magnetic field under the influence of electromagnetic force. . It is brushless, which is also one of its advantages. It can speed up the motor running rate, and is conducive to the cooling and heat dissipation and rapid heat dissipation of the AC motor. Therefore, the number of parts required for the AC motor of the electric hydraulic pallet truck is greatly reduced compared to the DC motor, which reduces the wearing parts that are regularly replaced, and is almost maintenance-free, efficient and durable.

Even so, in the face of severe cold weather, there is a relatively rigorous demand for the control of pallet trucks. It is generally recommended that the battery pallet truck should be parked in an environment above 0°C in winter, which is to avoid the electrolyte freezing and forcing the battery pack to blow up. When replenishing distilled water, it is also required to be evenly mixed with the electrolyte, otherwise it will burst. Because under high temperature conditions, distilled water will freeze on the upper layer of the electrolyte. The batteries that are not used by the electric hydraulic pallet truck should be stored in a warm environment, the liquid level should be checked every half month, and the power maintenance should be checked once a month to ensure that the batteries can survive the winter safely.

The tires of battery pallet trucks should also be maintained. Usually check the tread pattern and remove the foreign matter stuck in it, check the tire pressure, replace the safety thread, and check whether the nut is tightened. Remind everyone that it is strictly forbidden to overload and drive for long distances, and it is strictly forbidden to brake suddenly or make sharp corners. Indoor storage, away from heat sources, oil, acid and alkali, and not exposed to the sun.

During the driving process of the battery pallet truck, it is necessary to slow down when encountering uneven places to avoid tire damage. Remind everyone to drive on a dry road surface as much as possible to prevent the wheels from hardening and embrittlement. Also, avoid overweight work. Because the material of the electric hydraulic pallet truck is easy to change and become brittle in winter, it is easy to damage and cause personal injury when working in a low temperature environment.
