Crane cab vibration-damping equipment - has spring components with adjustment of distances to housing and supporting arm

摘要

The working platform vibration-damping equipment is particularly for a crane cab, having a number of damper units each with spring components secured by a supporting arm to the cab etc. Each spring component (14) has an adjusting member for the distances between it, its housing (9) and its supporting arm (11). In addition, the cab etc. is coupled to its mounting via a number of shock dampers with moving levers, so that when it moves in one direction it does so with only one damper, and when moving in the two other directions this damper is not effective.
