The proper functioning of steel wire ropes plays a crucial role in ensuring the normal and safe operation of port cranes. Before starting the machinery, the inspection of the wire ropes must not be taken lightly. It must be carried out in strict accordance with national regulations, starting from the outside and moving inwards. External […]

When lifting heavy objects, the hook wire rope should remain vertical. It is not allowed to drag the lifted object diagonally. When lifting heavy objects, the center of gravity should be accurately located and the object should be firmly bound. If there are sharp corners, they should be padded with wooden blocks. Before the heavy […]

(1) The deviation of the position of the girder center line from the designed positioning axis shall not be greater than 5 mm. The alignment of the girder’s center line is crucial as it serves as the central axis for the entire crane structure. Even a minor deviation exceeding 5 mm can cause misalignment of […]

(1) The deviation of the actual centerline of the track from the actual centerline of the crane girder shall not be greater than 10 mm. Precise alignment of these centerlines is fundamental. In large industrial workshops where cranes operate continuously, any misalignment here can lead to uneven stress distribution on the crane structure during movement. […]

The static load test shall be carried out according to the following procedures and requirements. Park the crane at the column. First, start the hoisting mechanism to conduct no-load lifting and lowering operations, and make the trolley run back and forth along the whole journey. This no-load trial operation shall be carried out no less […]

The winter maintenance of construction machinery is of great significance. Especially in the northern regions where winters are long and the temperature remains low for extended periods. When construction machinery is used in winter, the cold climate can easily lead to difficulties in starting internal combustion engines, freezing of cooling water and electrolyte, intensified wear […]

The reasons for the downward deflection of the main girder of overhead cranes are multifaceted and should be analyzed according to specific circumstances. Generally speaking, issues can arise from design, tlhahiso, sepalangoang, ho kenya, and use. (1) The Impact of Unreasonable DesignIn the past, China followed the Soviet standards. The static stiffness of the main girder […]
