The height-adjustable installation foot has a threaded rod as part of a threaded spindle for height adjustment.

Abstract: A counterweight for an elevator system has an asymmetrical cross section in a horizontal sectional plane. The asymmetrical cross section results in an improved connection of the counterweight to a guide rail, a reduction in a number of components, in particular guide rails, for the elevator system, and a reduction in an installation space for the elevator system thereby simplifying installation of the elevator system.

Abstract: A safety brake for a traveling body in an elevator system brakes against a brake rail oriented in a traveling direction. The safety brake includes a housing with a catch element and a brake pad attached to the housing opposite one another. The catch element is mounted on the housing such that an application movement of the catch element relative to the housing is possible, and the application movement reduces an opening width between the brake pad and the catch element. At least the catch element or the brake pad has a notch for fitting around a protrusion of a brake rail during braking. The opening width corresponds to at least twice the depth of the notch.

Abstract: A method for forming and smoothing a hollow-profile guide rail of an elevator system uses a smoothing apparatus to smooth mutually opposing surfaces on a hollow-profile guide rail. The smoothing apparatus includes a guide device, a removal device and a pressing device. The guide device has rollers for moving in a low-friction manner in a longitudinal direction along a first of the opposing surfaces and to thus guide the smoothing apparatus along the first surface. The pressing device has spring elements to press the removal device away from the guide device and toward a second of the opposing surfaces. The removal device has a rasp element to remove material from the second surface during a movement in the longitudinal direction along the second surface.

Abstract: 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.
