The summer solstice, which means the hottest day of the year is coming! The outdoor ambient temperature is often 30 ~ 40 degrees, which is a severe test for the motor, electric control, battery and hydraulic system. Especially for forklifts with harsh operating environment, high operating intensity and long continuous service 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. Regularly check whether the bolts at each part of the battery, motor and electric control are loose. The vibration intensity of the forklift truck is relatively high. The bolts in these parts often become loose after a period of use, and these parts often work with high current for a long time. The loose parts of the bolts will be heated and easy to burn.
2. Check the heat dissipation measures of the motor and the electric control, and often remove dust from the motor shell and the electric control heat dissipation bottom plate. The accumulation of dust, especially oily dust, on the motor and electric control will greatly reduce the heat dissipation capacity of the motor and electric control. As summer approaches, it is necessary to thoroughly clean the motor shell and the electric control cooling bottom plate. In addition, for those designs with congenital insufficient heat dissipation measures, additional heat dissipation measures should be considered, such as installing high-power heat dissipation fans on the motor or on the electric control base plate. For the motor or electric control that uses the cooling fan for heat dissipation, it is necessary to frequently remove dust from the cooling fan to prevent the cooling fan from being stuck and damaged by accumulated dust and debris, which will affect the heat dissipation of the motor and electric control.
3. The electrolyte level and density of the battery need to be checked frequently. At present, most of the lead-acid batteries on the market are liquid filled. Before each charging, check whether the liquid level of each monomer is normal, clean the battery surface, and immediately supplement distilled water after charging (note that ordinary tap water or mineral water must not be used).
4. Always check whether the hydraulic control switch and potentiometer signal are reset well. The switches and potentiometers of the hydraulic control levers of some forklifts will not reset well after a period of use, which will cause the oil pump motor to run at high speed and fail to stop even if the hydraulic action is not operated. In serious cases, the oil pump motor and electric control of the oil pump will overheat and burn out.
