What Causes Heavy Steering Wheel in Forklifts?
2 Answers
The reasons for heavy or stuck steering in forklifts may include: Reason 1: The upper and lower steering column bearings are adjusted too tightly or damaged. Reason 2: The meshing clearance between the rack and sector gear is adjusted too tightly. Reason 3: The ball joint assemblies of the tie rods are adjusted too tightly. Reason 4: The tie rods or steering axle are bent or deformed. Reason 5: Poor lubrication in the forklift steering system, such as insufficient oil in the steering gear. Untimely lubrication of ball joints increases frictional resistance. Additional information: Inspection: When turning the steering wheel, if it feels light, it indicates the steering gear is functioning properly. Check if the transmission mechanism is too tight or poorly lubricated, and adjust or lubricate as necessary. If all the above conditions are normal: Then inspect whether the steering axle is deformed and whether the forklift tires have adequate air pressure.
I've been driving forklifts for almost ten years and have encountered the issue of heavy steering many times. The most common cause is a problem with the hydraulic power steering system, such as low or dirty power steering fluid, which prevents the pump from working properly, making it harder to turn the wheel. Another reason could be insufficient tire pressure; low pressure increases friction between the tires and the ground, making the steering wheel particularly heavy when turning. Additionally, lack of lubrication or aging and deformation of the steering mechanism bearings can also increase resistance. Remember to regularly check the power steering fluid level and cleanliness, and it's best to change the fluid every six months to significantly reduce the occurrence of such issues. By the way, for electric forklifts, loose electrical connections or insufficient battery power might also cause reduced power. In short, the specific cause should be determined based on the model of the forklift.
