The rotation of the roller shall be flexible. The rollerand shaft shall be free from cracks and defects. The amount of wheel groovewear must not exceed 10% of the original size.
2.The tension of the two lifting chains should be uniform, not to be distorted,the ends are firmly connected, and the pitch of the chain must not exceed 4% ofthe original length, otherwise the chain should be replaced. The sprocketrotation should be flexible.
3.The forks shall not be severely deformed and the welds shall be desoldered.There must be no cracks or welds on the surface of the fork. The root angle ofthe fork shall not be greater than 93° and the thickness shall not be less than90% of the original size. The height difference between the left and right forktips shall not exceed 3% of the length of the horizontal section of the fork.The positioning of the fork should be reliable. The bearing surface and thepositioning surface of the fork should not have obvious defects. The clearancebetween the fork and the fork should not be too large and the movement shouldbe smooth.
4.The connection between the lifting cylinder and the door frame should be firm.The hinge of the tilting cylinder and the door frame and the frame should befirm and flexible, and the matching clearance should not be too large. Thecylinder should be well sealed, free of cracks and stable. Under the ratedload, the self-sinking of the gantry is not more than 20mm and the inclinationis not more than 0.5°. The lifting speed should not be less than half of thestandard value at full load.
