The crane beam is generally installed in the upper part of the factory building. It is the roadbed of the crane. There are crane tracks on the crane beam, and the crane travels back and forth on the crane beam through the track. There are many types of beams, often welded, box-type, and simple, generally reinforced concrete or steel structures.
The force position of the crane beam determines the safe working area of ​​the crane. The movement on the crane beam produces dynamic loads in three directions: vertical, lateral and longitudinal horizontal loads.
Vertical load: The vertical load standard value of the crane beam should be the maximum wheel pressure or minimum wheel pressure of the crane. When the crane runs along the track, hoists, unloads and the workpiece is turned over, it will cause the crane beam to vibrate.
Lateral load: The connection between the end of the crane beam and the column should seek to reduce the additional stress generated at the joint due to the bending deformation of the crane beam.
Longitudinal load: Longitudinal horizontal load refers to the braking force of the crane, which is transmitted from the crane beam to the column support along the track direction. The calculation of the crane beam section is not considered.
