Abstract

See full text

A drive device for a protective hood of a machine includes a counterweight, a pulling means connecting the protective hood to the counterweight, a motor, and a freewheel. The freewheel connects the motor to the pulling means and is arranged to block when a weight force of the protective hood is greater than a weight force of the counterweight. The freewheel may be a linear freewheel or the freewheel may operate between two rotatable elements. The freewheel may be a frictionally locking freewheel or a positive locking freewheel.
