An elevator system includes one or more rails fixed in a hoistway and an elevator car configured to move through the hoistway along the one or more rails. The system includes one or more braking systems having one more braking surfaces secured to the elevator car and frictionally engageable with one or more rails of the elevator system. One or more actuators are operably connected to the one or more braking surfaces configured to urge engagement and/or disengagement of the one or more braking surfaces with the rail to stop and/or hold the elevator car during operation of the elevator system.

A brake device for an elevator system with a travel body movable in an elevator shaft along a guide and/or brake rail brakes and retains the travel body on the rail as required. The brake device includes a control plate receiving a brake body and for positioning the brake body relative to the rail. The brake body has first and second brake elements pivoted about a common axis. The first brake element is for braking and retaining purposes when the travel body is moving along the rail in an upward direction, and the second brake element is for braking and retaining purposes when the travel body is moving along the rail in a downward direction.

In a safety brake device for a conveying device, a brake shoe is designed to engage at a rail arranged parallel to the conveying route in a stationary manner when the device is triggered. An engagement lever on the rail side opposite the shoe is pivotable between a release position and at least one brake position. In the brake position, the rail is clamped between the end of the engagement element and the shoe. The engagement element is pivotable using a trigger lever, so that, in each brake position of the trigger lever, the engagement element is also in a brake position. The trigger element is mounted to be displaceable along or parallel to its longitudinal axis and has a first end position in the vicinity of the rail and another end position at a distance from the rail. An electrically controllable actuation arrangement prevents or causes this displacement.

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.
