ABSTRACT:
A device for facilitating the alignment of heavy workpieces at a machine table or the like, comprising a housing capable of being arranged below the workpiece at the machine table. A pendulum support is arranged in the housing so as to have a limited tilting movement to all sides and equally can be moved between a rest position and support position where it supports the workpiece. The pendulum support is arranged so that it can be selectively raised and lowered. Further, there is provided a mechanically adjustable support which is guided so that it can be raised and lowered. The mechanically adjustable support is guided in the housing between a rest position and a support position where it supports the workpiece instead of the pendulum support.
