Abstract
A handgrip, having dead-man-switch action, for mounting on the pole of construction equipment. The inventive handgrip is distinguished from known handgrips by increased operating comfort, simpler construction, and a more difficult-to-circumvent safety mechanism. The handgrip has a grip member that is displaceable in a support on the pole in its longitudinal direction and against spring force. At least one of the ends of the grip member has a limited freedom of movement in the radial direction. Also provided is a positively active slide coupling that displaces the grip member in the longitudinal direction relative to the support when the grip member is displaced in the radial direction relative to the support. The longitudinal displacement of the grip member is transmitted to a switching member for drive operation.
