Abstract:
A safety device configured to aid in braking movement of a hoisted object is provided including a mounting frame. A brake block is connected to the mounting frame and is operably coupled to a safety brake. An inner block assembly is disposed between the mounting frame and the brake block. The inner block assembly is movable relative to both the mounting frame and the brake block. Upon detection of a predetermined condition, the brake block is configured to engage and adjacent guide member to actuate the safety brake.
Abstract:
A braking device is operable to aid in braking a hoisted object relative to a guide member. The braking device includes a mounting structure connected to the hoisted object, and first and second brake pads positioned on the mounting structure on opposing sides of a passageway through which the guide member extends. The first and second brake pads each include a contact surface that is operable to frictionally engage the guide member. The second brake pad engages the mounting structure in a manner that enables the second brake pad to move relative to the mounting structure between a non-braking position and a braking position. The braking device includes a brake initiator that is selectively operable to initiate movement of the second brake pad from the non-braking position toward the braking position by selectively actuating an actuatable portion of the brake initiator from a non-deployed position to a deployed position.

The intelligent surface system includes a personnel movement device (PMD) configured to move an individual between first and second locations, sensors deployed to sense characteristics of the individual and a controller configured to determine a condition of the individual based on the characteristics and control an operation of the PMD in accordance with the determined condition of the individual.
Abstract:
A brake assembly for an elevator system includes a guide rail configured to guide movement of an elevator car. Also included is a safety brake operatively coupled to the elevator car and having a brake surface configured to frictionally engage the guide rail. Further included is a safety brake actuation mechanism operatively coupled to the safety brake and configured to actuate the brake member to a braking position. The safety brake actuation mechanism includes a sensing device disposed at a distance from the guide rail to determine a speed of the elevator car relative to the guide rail. The safety brake actuation mechanism also includes a first rigid plate having an inner edge disposed at a distance from the guide rail that is less than the distance that the sensing device is spaced from the guide rail to prevent the sensing device from contacting debris disposed on the guide rail.

A brake assembly for an elevator system is provided and includes a guide rail configured to guide movement of an elevator car. Also included is a safety brake operatively coupled to the elevator car and having a brake surface configured to frictionally engage the guide rail. Further included is a safety brake actuation mechanism operatively coupled to the safety brake and configured to actuate the safety brake to a braking position. The mechanism includes a first sensing device disposed on a first side of the guide rail to detect a first condition reading of the elevator car relative to the guide rail. The mechanism also includes a second sensing device disposed on a second, opposite side of the guide rail to detect a second condition reading of the elevator car relative to the guide rail, the first and second condition readings collectively analyzed to determine an overall condition reading.
Abstract:
A brake (26) for an elevator system (10) and method of using the brake (26) is disclosed. The brake (26) may comprise first and second brake linings (38) configured to be frictionally engageable with a rail (14) of the elevator system (10), a first biasing member (34) configured to urge the first brake lining (38) to engage the rail (14), and a first actuator (30) configured to move the first brake lining (38) to disengage the rail (14) when the first actuator (30) is energized. The brake (26) may be configured to be mounted on an elevator car (16) of the elevator system (10).
Abstract:
A ropeless elevator system (80) is disclosed. The ropeless elevator system (80) includes a plurality of hoistways (22, 26, 72) in which a plurality of elevator cars (24) circulate to a plurality of floors. Each hoistway (22, 26, 72) is assigned to a single direction of travel for the elevator cars (24). The single direction of travel is either upward or downward. A first quantity of upward hoistways (86) is unequal to a second quantity of downward hoistways (88), and a speed of each of the plurality of elevator cars (24) in the upward hoistways (86) is greater than a speed of each of the plurality of elevator cars in the downward hoistways (88).
