90 t crane company | Yongchang Machinery (certified) | 90-ton crane

Crane use and maintenance: Running characteristic period. Poor lubrication: As a new assembly of parts with the gap is small, and due to assembly and other reasons, it is difficult to ensure uniformity with the gap 90 tons crane sales company, oil (fat) in the friction surface is not easy to form a uniform film used 90 tons crane price, to prevent wear. Thereby reducing lubrication performance, resulting in the early parts of abnormal wear. It will cause serious friction with precision surface scratches or bite phenomenon Buying 90 t crane, resulting in failure. Crane main performance parameters indicators: Lifting range. Amplitude: the amplitude of the rotation arm erecting cranes means the horizontal distance the rotation center line and extract means between plumb line, the unit is m. Non-rotating type of jib crane spreader magnitude refers to the centerline of the rear axle or other typical water arm axis between the horizontal distance.
