The risk of tipping over is dependent on the load-bearing capacity of the base on which the crane is standing. Before lifting anything, therefore, the load-bearing capacity of the base must be documented. Supporting legs must be used as described in the crane’s usage instructions, and the maximum supporting leg pressure will also be specified here.
Supporting legs must be folded out (extended) so that they correspond to the load and layout in question.
All supporting legs must be placed on a load-bearing base – where necessary, use panels beneath supporting legs to distribute the load over the base.
If the crane is to move with the load elevated, the base must be flat and secure, corresponding to a road finished with surfacing (asphalt). Otherwise, driving panels must be laid out.
