In high-frequency forklift operation of overseas warehouses, ports and processing factories, forks bear all load pressure and wear rapidly. Unregulated operations such as eccentric loading, unilateral load and cargo dragging cause fork bending, thickness wear and cracks, leading to uneven cargo stacking and serious falling risks. Centered and uniform loading, no eccentric load and cargo dragging, and avoiding collision with shelves and hard ground effectively reduce fork deformation and wear. Regularly check fork thickness, flatness and cracks, correct slight deformation in time, and replace severely aging parts. Standard fork maintenance ensures warehouse operation safety, extends accessory service life and reduces long-term replacement costs.
