摘要： Embodiments herein are directed to an elevator counterweight governor assembly for an elevator assembly. The elevator counterweight governor assembly includes a swing arm, a first pulley assembly, a second pulley assembly, a third pulley assembly, and a braking assembly. The swing arm is pivotally coupled to the at least one inner beam at one end. The swing arm is configured to pivot between a disengaged position and an engaged position. The braking assembly is configured to move between an unactivated state where the braking assembly is free from the fixed member and an activated state where the braking assembly engages with the fixed member to inhibit movement of the counterweight frame. When the swing arm is in the disengaged position, the braking assembly is in the unactivated state and when the swing arm is in the engaged position, the braking assembly is in the activated state.

摘要： An externally powered car brake for a lift system and, for the activation thereof, a circuit arrangement with integrated stepped control of the deceleration of the car during emergency braking are proposed.
According to the invention, a braking system having the full braking force or a braking force adapted to the operating parameters and a subsequent control of the deceleration on the basis of an acceleration measurement with stepped reduction of the braking force are proposed.
The control is designed such that the deceleration of the car is always within predefined threshold values, which applies independently of the direction of travel of the lift car, independently of the drive system of the lift used, and independently of the car loading and of the friction coefficient between the brake lining and the guide rail.-

摘要： A frictionless safety brake actuator, for use in an elevator system, includes at least two stators; a magnet array positioned between the stators; a linkage attached to the magnet array; and a biasing arrangement. The linkage is actuatable to move a safety brake into frictional engagement with an elevator guide rail. The magnet array is moveable between a first position in which the linkage is actuated and a second position in which the linkage is not actuated. The biasing arrangement is arranged to bias the magnet array towards the first position. The magnet array includes a first magnet set and a second magnet set which comprise at least one magnet each and at least three magnets in total. The magnet(s) of the first magnet set is/are arranged alternately with the magnet(s) of the second magnet set in a stack.

摘要： An elevator safety clamp control device, an elevator safety apparatus and an elevator system. The elevator safety clamp control device includes an operating portion arranged on a running device running along an elevator guide rail and connected to an elevator safety clamp, the operating portion release kinetic energy when controlled to enter a second state from a first state of energy storage, for actuating the elevator safety clamp to engage with the elevator guide rail to stop the running device; a control portion configured to control the operating portion to be in the first state, and to control the operating portion to enter the second state from the first state to release kinetic energy when an operating parameter of the running device exceeds a threshold; and a power portion arranged on the running device and connected to the operating portion.

摘要： A safety brake actuation mechanism for a hoisted structure includes a housing operatively coupled to the hoisted structure. Also included is a first brake member coupled to the housing, the first brake member moveable between a braking position and a non-braking position. Further included is a retaining assembly moveable between a first position and a second position and engageable with the first brake member, the retaining assembly retaining the first brake member in the non-braking position in the first position and permitting the first brake member to move to the braking position in the second position. Yet further included is an electric actuator operatively coupled to the retaining assembly and biasing the retaining assembly to the first position in a powered state of the electric actuator, the retaining assembly movable to the second position in a non-powered state of the electric actuator.
