# Forklift Operation Safety Requirements

1. The mast must not be deformed, and the welds must not be detached. The rolling clearance between the inner and outer masts should be reasonably adjusted and must not exceed 1.5 mm; the rollers should be flexible, and the wheel axles should have no cracks or defects. The wear amount of the wheel groove must not exceed 10% of the original size. 2. The tension of the two lifting chains should be uniform, and they must not be twisted or deformed, and both ends should be firmly connected. The chain pitch should not exceed 4% of the original length; otherwise, the chain should be replaced. The sprocket should rotate flexibly. 3. The fork rack must not be severely deformed, and the welds must not be detached. The fork surface must have no cracks or welds. The root angle of the fork must not exceed 93°, and the thickness must not be less than 90% of the original size. The height difference between the left and right fork tips must not exceed 3% of the length of the horizontal section of the fork. The positioning of the fork should be reliable, the load-bearing surface and positioning surface of the fork hook must have no obvious defects, the fit clearance between the fork and the fork carriage should not be too large, and the movement should be smooth. 4. The connection between the lifting cylinder and the mast should be firm, and the hinges between the tilt cylinder and the mast and frame should be firm and flexible, and the fit clearance should not be too large. The cylinder should be well sealed, free of cracks, and operate smoothly. Under rated load, the self-settling amount of the mast in 10 minutes must not exceed 20 mm, and the tilt angle must not exceed 0.5°. At full load, the lifting speed should not be less than half of the standard value. 5. The guard frame and backrest must be complete and effective. 6. It is strictly prohibited to stand on the fork to work, and it is not allowed to use a single fork to lift overweight goods. 7. Forklift drivers should be equipped with a forklift driving license, and avoid one forklift being driven by multiple drivers.
