It's summer solstice, which means the hottest day of the year is coming! The outdoor environment temperature is always 30-40 degrees, which is a severe test for the motor, electronic control, battery, and hydraulic system. Especially for forklifts with harsh operating environment, high operating intensity and long continuous use time, special attention must be paid to the maintenance and temperature monitoring of forklift components. It is recommended to pay special attention to the following points:
1. Always check the battery cells, motors and electrical control bolts for looseness. The vibration intensity of the forklift is relatively large. The bolts in these parts are often loose after a period of use, and these parts are often operated with high current for a long time. The loosened parts of the bolt will become hot and easily burned.
2. Check the heat dissipation measures of the motor and electric control, and often remove dust from the motor housing and the position of the electric control heat dissipation bottom plate. The accumulation of dust, especially oily dust on the motor and the electric control will greatly reduce the heat dissipation capacity of the motor and the electric control. As summer approaches, it is necessary to thoroughly clean the motor housing and the electronically controlled heat dissipation bottom plate. In addition, for those designs with inadequate heat dissipation measures, additional heat dissipation measures should be considered, such as installing a high-power cooling fan on the motor or the position of the electronic control board. For motors or electronic controls that use a cooling fan to dissipate heat, the cooling fan needs to be regularly dedusted to prevent the cooling fan from being stuck and damaged by accumulated dust and debris, which in turn affects the heat dissipation of the motor and electronic control.
3. The electrolyte level and density of the battery need to be checked frequently. Most lead-acid batteries currently on the market are liquid-filled. Before each charge, check whether the level of each monomer is normal, clean the surface of the battery, and add distilled water immediately after charging (note that ordinary tap water or mineral water must never be used).
4. Always check whether the hydraulic control switch and potentiometer signals are reset well. Some forklift hydraulic joystick switches and potentiometers will not reset well after a period of use. This situation will cause the pump motor to stop running at high speed even if the hydraulic action is not operated. The oil pump motor and oil pump are overheated and burned.
