STABILIZING ASSEMBLIES AND METHODS OF USE THEREOF
Embodiments here are directed to an elevator stabilizing assembly for energy dissipation of an elevator assembly is provided. The elevator stabilizing assembly includes an actuator and a stabilizing device. The actuator is configured to move between a retracted position and an extended position. The stabilizing device includes an arm and a biasing member. The biasing member is coupled to the arm and biases the arm to move the arm between a disengaged position and an engaged position. When the actuator is in the extended position, the arm is moved into the engaged position when at least a portion of the arm is in contact with the fixed member of a hoistway. When the actuator is in the retracted position, the arm is moved into the disengaged position such that the at least the portion of the arm is free from contact with the fixed member of the elevator assembly.

A stabilizing device of an elevator car and an elevator system. The stabilizing device include a first frame body, a second frame body, a left electromagnetic block, a right electromagnetic block, a left damper and a right damper, wherein the left electromagnetic block and the right electromagnetic block are mounted within the second frame body in a limiting manner in an up-down direction and are moveable in a left-right direction, and the left damper and the right damper are arranged in the up-down direction. The fixed end of the left damper and the fixed end of the right damper are mounted within the second frame body in a limiting manner in the up-down direction, and the movable ends of the left damper and the right damper are connected to the first frame body and are moveable upwardly and downwardly together with the first frame body.
BRAKE DEVICE FOR AN ELEVATOR CAR, COMPRISING AN INTEGRATED LOAD MEASURING DEVICE, USE THEREOF IN AN ELEVATOR SYSTEM, AND METHOD
A braking apparatus, that brakes and measures load changes in an elevator car, includes a brake, a brake holding arrangement holding the brake on the car, a load measuring device measuring a force acting on a force transmission element and a load measuring device holding arrangement holding the load measuring device on the car. The brake can be displaced relative to the car in a force direction generated by the brake and the load measuring device is held on the car fixed relative to the car in the force direction. The force transmission element is operatively connected to the brake to measure a force acting between the brake and the load measuring device due to a relative displacement of the brake relative to the load measuring device. A connecting piece arrangement connects the load measuring device holding arrangement and the brake holding arrangement in an elastically deformable manner.
SAFETY BRAKE SYSTEM
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.
Elevator car parking brake
According to an aspect, there is provided an elevator car parking brake. An operating fork is configured to move within a housing in a direction perpendicular to an end surface of a guide rail in response to operating an actuator. When the actuator is operated to move the operating fork within the housing towards the guide rail to achieve a braking state, the operating fork is configured to push braking wedges towards side surfaces of the guide rail to contact the side surfaces. When the actuator is operated to move the operating fork within the housing away from the guide rail to achieve a brake release state, detaching means are configured to pull the braking wedges away from the side surfaces of the guide rail.
BRAKE DEVICE
A brake device for a traveling body of an elevator installation brakes on a rail having first and second braking profiles. The brake device includes a forcing element and a counter-support. The forcing element has first and second forcing working faces for acting on the first and second profiles respectively. The counter-support has a first counter-support working face for acting on the first profile, and a second counter-support working face for acting on the second profile. The first forcing working face and the first counter-support working face are arranged opposite one another at the first profile and the second forcing working face and the second counter-support working face are arranged opposite one another at the second profile. The forcing element is spread to bring the first forcing working face into contact with the first profile and the second forcing working face into contact with the second profile.
Caliper brake for an elevator system used as a holding and safety brake
An elevator system caliper brake includes first and second brake levers each with a brake pad wherein the brake levers move the brake pads relative to one another along an actuation axis. The first brake lever is rotatably mounted at a stationary first mounting point at a housing of the brake, and the second brake lever is rotatably mounted at a second mounting point on an intermediate lever that is rotatably mounted at the brake housing. A tension element can be moved approximately parallel to an actuation axis and is connected to the brake levers at mounting points between the respective brake pads and the brake lever mounting points. A closing spring moves the first and second brake levers to decrease the distance between the brake pads and a linear spindle drive connected to the intermediate lever selectively counteracts the closing spring to increase the distance between the brake pads.
