(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. […]

Precautions Before Installation 1. Preparation of Bearings Since bearings are treated with anti-rust measures and packaged, do not open the package until just before installation. 추가적으로, the anti-rust oil coated on the bearings has good lubricating properties. For general-purpose bearings or bearings filled with grease, they can be used directly without cleaning. 하지만, for instrument […]

(1) It is suitable for continuous and single tasks. In industrial production lines, for example, when a particular operation needs to be carried out repeatedly without much variation, the spring balancer can provide consistent support. This kind of continuous work often occurs in packaging processes, where the same item is repeatedly lifted, moved, and placed. […]

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 […]

Tower cranes are large-scale hoisting machinery commonly used in building construction. Due to the structural characteristics of tower cranes, the tower body bears relatively large eccentric bending moments. 그러므로, their installation and dismantling require strong technical skills, and safety management is rather difficult. A slight oversight can lead to major accidents with the destruction of […]
