摘要： A brake device for braking a traveling body movable along a guide rail in a movement direction includes a holder mounting a brake element that has a brake surface directed toward the guide rail, the brake element being movable relative to the holder between a free-running position and a braking position. A pretensioning element is activated to exert a force that moves the brake element toward the braking position. A release element holds the pretensioning element in a holding state and is activated into a released state to reconfigure the pretensioning element from a deactivated configuration into the activated configuration. A pressing element in an actuated state generates a force on the brake element in a direction toward the guide rail to enable a reset of the brake device.

摘要： An elevator apparatus provided with a safety gear is disclosed which is adapted to prevent the turn-on of a brake state detection switch during power outage even while being operated by an electric actuator. This elevator apparatus includes: a safety gear 5 disposed at a car 1; and an electric actuator 3 for operating the safety gear. The elevator apparatus further includes a brake state detection switch 6 for detecting a brake state of the safety gear. The brake state detection switch is operated by a mechanism 8 which operates the safety gear with an operation of the electric actuator. The brake state detection switch is in an off state for a displacement of the mechanism during interruption of power supply. The brake state detection switch is turned on for the displacement of the mechanism during the brake of the safety gear.

摘要： A method of resetting a safety actuator (52) in an elevator system. An elevator controller receives a signal to reset the safety actuator (52) and moves the elevator car upwards relative to the guide rail (106a) so as to release the safety brake (48). A safety board controller is instructed to operate an electromagnet (62) in the safety actuator (52) to pull a magnetic actuator pad (54′) laterally away from the guide rail (106a) to a reset position while the elevator car is moving upwards during the reset operation.

摘要： A safety brake includes a first brake element, a first guide element, and an actuating element. The first brake element is mounted in a displaceable manner in a linear bearing on the first guide element. The first guide element can be moved between a rest position and a braking initial position. The actuating element is designed to move the first guide element from the rest position into the braking initial position, more particularly to activate the safety brake. The first brake element can carry out a braking movement from the braking initial position into a braking position. The braking movement returns the first guide element to the rest position. The first guide element is guided on a first parallelogram guide.

摘要： A safety brake system for use in a conveyance system is provided. The safety brake system includes a guide rail and a conveyance component moveable along the guide rail. The safety brake system comprises: a safety brake moveable between a non-braking position where the safety brake is not in engagement with the guide rail and a braking position where the safety brake is engaged with the guide rail; a linkage mechanism; and an actuator for the safety brake. The actuator is configured to be mounted to the conveyance component. The actuator comprises an electromagnet switchable between a first state and a second state; and an actuation component configured to move relative to the electromagnet from a first position when the electromagnet is in the first state to a second position when the electromagnet is in the second state.
