1, insufficient tire pressure: insufficient tire pressure reduces the contact area between the tire and the ground, reduces the friction, and is prone to tire mopping.
2. Uneven tire wear: uneven tire wear, inconsistent tire tread depth, inconsistent tire contact area with the ground, and different friction forces are prone to tire mopping.
3. Failure of rear wheel steering system: Failure of rear wheel steering system, such as damaged steering bearing and loose steering rod, will lead to inaccurate steering of rear wheel, uneven contact area between tire and ground and easy tire dragging.
4. Improper driver's operation: Improper driver's operation, such as sudden braking and sharp turning, will cause the vehicle to lose its balance, and the contact area between the tire and the ground is uneven, which is prone to tire mopping. In order to prevent the tires from mopping the ground when the rear wheels of a four-wheel drive forklift truck turn, the tire pressure and wear should be checked regularly to keep the steering system running normally, and the driver's operation skills should be paid attention to to to ensure the smooth and safe driving of the vehicle.
