Disclosed is an elevator system, having: a car mover for moving an elevator car along a drive track in a hoistway, the car mover having: motor controlled wheels, wherein the car mover is configured to control the motor controlled wheels to move along the drive track; and a parking brake, operationally connected to the car mover and/or elevator car and operationally separate from the motor controlled wheels, wherein the car mover is configured to control the parking brake to move between a deployed state and a retracted state, wherein in the deployed state, the parking brake engages the drive track at a location that is spaced apart from the motor controlled wheels to park the car mover and/or elevator car along the hoistway, and in the retracted state, the parking brake is spaced apart from the drive track.

An elevator safety device comprises a housing attachable to an elevator car or to an elevator counterweight of an elevator system, the housing comprising a passage for allowing a guide member to pass through. A brake shoe is attached to the housing and is located on a first side of the guide member. A support element is arranged on a second of side of the guide member, the support element extending at an angle with respect to the guide member, thereby defining a tapered region between the guide member and the support element. A movable braking element is rotatable around a rotation axis of the movable braking element. The movable braking element is, at least in an activated condition of the elevator safety device, arranged within the tapered region defined by the support element and the guide member. The movable braking element is capable of rotatingly moving along the support element into a wedged condition between the support element and the guide member. The movable braking element has, in a plane that is oriented perpendicularly to the rotation axis, a non-circular cross-section, which is defined by a closed curve having a constant width.

The brake device for an elevator includes a frame configured to be rigidly attached to an elevator car or to a stationary body part of a hoisting machinery, a brake caliper slidably mounted to the frame, a brake element mounted to the brake caliper, brake actuator and brake release for moving the brake element between a braking position and a retracted position, a fluid chamber, and a piston having a first piston surface delimiting the fluid chamber. One of the fluid chamber and the piston is configured to move with the brake caliper and the other is configured to move with the frame such that a brake force applied to the guide rail or to the brake disc by the brake device strives to move the piston and the fluid chamber relative to each other.
