Patent ID: 7036638

Claim:
A safety brake device for a load receiving means of vertical conveying equipment, comprising: a housing adapted to be attached to the load receiving means; at least one brake wedge arranged in said housing and being responsive to a triggering of a braking action to move in a direction for engaging a guide rail of the conveying equipment with a wedge effect for braking the load receiving means; a spring element mounted in said housing and applying a spring force to said at least one brake wedge; an abutment positioned to limit movement of said at least one brake wedge in said direction thereby limiting a braking force applied by said spring element through said at least one brake wedge; and a setting device connected to one of said abutment and said housing for selectively automatically positioning said one of said abutment and said housing in response to changes in an input signal representing an actual mass of the load receiving means to be braked, whereby when said housing is attached to the load receiving means and moved along the guide rail and a braking action is triggered to brake the load receiving means from a travel condition to a stopped condition, said at least one brake wedge responds to the triggering by moving in the direction into contact with the guide rail and applying a braking force to the guide rail limited by the position of said one of said abutment and said housing selected by said setting device in response to the last of said changes in said input signal.
