Abstract: An elevator brake disk assembly is provided. The elevator brake disk assembly includes a brake disk which is keyed to and rotatable with a shaft of an elevator machine, a machine frame and dampers. The dampers are respectively anchored to the machine frame and biased to symmetrically hold the brake disk during rotations thereof.

Abstract: A dual machine arrangement is provided for a hoist assembly of an elevator system. The dual machine arrangement includes dual machines, each comprising a motor and a sheave, which is rotatable by the motor, a coupling by which respective ends of the sheaves of the dual machines are connected and drive circuitry configured to synchronize reverse operations of the dual machines to raise or lower a load.

CPC classification number: B66B13/30
Abstract: Elevator systems include an elevator car configured to travel along an elevator shaft, the elevator car having a car door and a car sill. One or more landings are arranged along the elevator shaft, the landings each having a landing door and a landing sill. An elevator coupling is provided that includes a car door coupling operably coupled to the car door and a landing door coupling operably coupled to the landing door. The car door coupling and the landing door coupling are selectively operable to drive operation of the car door and the landing door simultaneously and a sill gap between the car sill and the landing sill is less than 25 mm.

Abstract: This disclosure relates to an electromagnetic brake configured to slow a deceleration rate of a passenger conveyer, such as an elevator car, during braking. In particular, this disclosure relates to a passenger conveyer system including the electromagnetic brake and a corresponding method. An example system includes a controller and an electromagnetic brake. The electromagnetic brake includes a disc configured to interface with a drive shaft, a spring, and a plate biased in a first direction into engagement with the disc by a bias force of the spring. The electromagnetic brake further includes an electromagnet selectively activated in response to a command from the controller to produce a magnetic field attracting the plate in a second direction opposite the first direction to partially offset the bias force of the spring. Further, when the electromagnet is activated, the plate engages the disc.

Abstract: An illustrative example embodiment of an elevator door lock includes a latch that is moveable between a locking position and a released position. The latch includes a locking surface configured to engage a stop when the latch is in the locking position. A magnet is situated to magnetically attract a portion of the latch to selectively move the latch from the locking position into the released position.

Abstract: An illustrative example embodiment of an elevator brake device includes a brake member configured to move into a braking position to resist movement of an elevator car associated with the brake device. A plurality of actuators are associated with the brake member and selectively controllable to apply a force to cause the brake member to move into the braking position. A brake controller determines a number of the actuators to activate based on a determined load of the elevator car associated with the brake device.
