Analysis of Common Problems and Solutions for Electric Forklift Manufacturers

Electric forklift manufacturer’s forklift drive axle oil leakage: all oil seals are damaged and need to be replaced; The gasket is damaged and needs to be replaced; Loose bolts require re tightening of bolts; The ventilation plug is blocked and needs to be cleaned to remove dirt.

Electric forklift manufacturer’s forklift drive axle heating: Lack of lubricating oil or oil deterioration, lubricating oil should be added or replaced; The bearing adjustment is too tight and needs to be readjusted.

Electric forklift manufacturers have loud noise in the drive axle of forklifts: insufficient lubricating oil is needed, and lubricating oil needs to be added according to specified requirements; Gears, bearings, and other parts that are excessively worn or damaged require inspection, repair, or replacement; Improper adjustment, excessive gear meshing clearance, or improper bearing preloading require re adjustment and inspection; The differential cross shaft transition is loose and needs to be replaced.

Electric forklift manufacturers are unable to establish pressure in the forklift oil circuit system: the oil circuit is not sealed in the high and low chambers, resulting in severe internal leakage. It is necessary to inspect the pipeline for dirt and replace the sealing components; The outlet backpressure valve does not generate backpressure, check, repair, and replace it; The oil pump is damaged and needs to be replaced.

High oil temperature in the torque converter of electric forklift manufacturers: the guide wheel is stuck or not rotating flexibly, requiring inspection, repair, and replacement; The working oil does not meet the requirements and needs to be replaced with new oil; If the oil level is too low or the system produces bubbles, increase the working oil to remove the bubbles; The oil pipe cooler in the system is blocked, requiring dirt from the system; Damaged bearings and gears need to be replaced; Serious internal leakage, check and replace the sealing components.

Electric forklift manufacturer’s forklift gearbox gear cannot be disengaged: the friction plate burns and needs to be replaced; The return spring is damaged and needs to be replaced; The blockage of the return oil circuit requires the removal of foreign objects; The micro valve brake interlock valve does not return and the spring needs to be replaced.

Electric forklift manufacturers have loud noise in their forklift gearboxes: gears or bearings are worn and need to be replaced; Insufficient bearing preload requires readjustment.

Electric forklift manufacturer’s forklift gearbox overheats: the oil level is too high or too low, and it needs to be adjusted according to regulations; Friction plate burning, replace the friction plate; The bearing gear is damaged and needs to be replaced.

Electric forklift manufacturer’s forklift gearbox brake valve stuck and not working: return spring failure, replace return spring.

Electric forklift manufacturer’s forklift gearbox cannot shift: the shifting pressure is insufficient, and the pressure regulating valve is too low. Adjust the pressure regulating valve to the specified value; The oil pump is not working properly and the seal is not good. Repair the oil pump and replace the seal; Pipeline blockage, oil filter element blockage, cleaning or replacing the filter element; The oil level is too low and the amount of oil is insufficient. It is necessary to add enough oil; The clutch sealing ring is damaged and leaking, replace the sealing element; The control valve stem is not in place, adjust to the correct position.
