Abstract:
A safety brake, generating a retardation-dependent braking force, for braking a load receiving means of an elevator, which safety brake is triggered by an elevator speed limiter in the case of excess speed of the load receiving means, comprising: a housing having a gap formed therein for receiving a guide rail, at least one brake wedge movable in said gap, a pressure body resiliently supported in said housing, and a stroke limiting device coupled to said at least one brake wedge wherein when said housing is attached to the load receiving means and receives an associated guide rail in said gap and when the elevator speed limiter moves said at least one brake wedge into contact with said pressure body and the guide rail to generate a braking force on the load receiving means, said stroke limiting device limits a penetration stroke of said at least one brake wedge in said gap in dependence on a retardation value of the load receiving means thereby controlling said braking force.
