What are the safety technical conditions of forklift lifting mechanism?
What are the safety technical conditions of forklift lifting mechanism? Answer: (1) the gantry shall be free from deformation and weld desoldering. The rolling clearance of the inner and outer gantry shall be adjusted reasonably, which shall not be greater than 15mm. The rolling rotation shall be flexible, and the roller and shaft shall be free of cracks and defects. The wear amount of wheel groove shall not be greater than 10% of the original size. (2) The tension of the two lifting chains shall be uniform without distortion, the ends shall be firmly connected, and the pitch of the chain shall not exceed 4% of the length, otherwise the chain shall be replaced. The sprocket shall rotate flexibly. (3) The fork frame shall not be seriously deformed; The fork surface shall be free of cracks; The welds of all parts shall not be desoldered, the fork root angle shall not be greater than 93%, and the thickness shall not be less than 90% of the original size; The height difference between the left and right fork tips shall not exceed 3% of the length of the horizontal section of the fork; The positioning of the fork shall be reliable, and the supporting surface and positioning surface of the fork hook shall not have obvious defects; The clearance between the fork and the fork should not be too large. (4) The connecting parts of the lifting oil cylinder and the gantry shall be firm, and the hinge of the tilt oil cylinder and the gantry and frame shall be firm and flexible, and the matching clearance shall not be too large. The oil cylinder shall be well sealed without cracks and work stably. Under the rated load, the self sinking amount of gantry in 10min shall not be greater than 20mm, and the inclination angle shall not be greater than 0.5 degrees. The lifting speed at full load shall not be less than half of the standard value.
