Abstract: An elevator safety brake (300) for use in an elevator system, the safety brake includes a safety block (310) substantially made of a polymeric material or a polymer-based composite material. The safety block (310) comprising: an elongate channel (320) defining a channel axis (325), wherein the elongate channel (320) is for receiving an elevator guide rail (330) of the elevator system when in use; and a cavity (340). The safety brake (300) further comprises a first braking component (250, 350) housed in the cavity (340), wherein the first braking component (250, 350) comprises a body (360) and a first braking surface (370). The safety brake (300) further comprises a second braking component (380) comprising a second braking surface (390). The first braking component (250, 350) is arranged on one side of the elongate channel and the second braking component is arranged on the other side of the elongate channel.

Abstract: An elevator system (1) including at least one refuge space (7, 8) and at least one sensor (9). The at least one sensor (9) is configured to detect weight in the at least one refuge space (7, 8) and produce at least one safety signal (21) indicating the presence of weight in the at least one refuge space (7, 8). The system can be used to improve the safety in the at least one refuge space (7, 8) in the event that the usual safety procedures have either failed or not been followed. For example, if for some reason the elevator system (1) has not been placed into a safe state before a maintenance worker (10) accesses the at least one refuge space (7, 8), the system will detect them and can produce at least one safety signal immediately indicating their presence in the at least one refuge space.
