An elevator system includes a car that can be moved along guide rails in an elevator shaft and a car apron attached to the car. The car apron is supported on the guide rails. The car apron is collapsible with two flat apron elements hinged together at a horizontal fold line. For the support, the car apron has a support structure that adjoins a lower end of the lower flat apron element and includes guide elements that engage the guide rails.

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.

A method for operating an elevator having a car, a drive engine, shaft doors, signal receptors, an engine controller and a door controller. Each of the shaft doors is reciprocally opened and closed by an associated active door drive and has one of the signal receptors thereat. The method includes: receiving a requesting signal at one of the signal receptors; responding to the requesting signal by instructing the engine controller to control the drive engine to displace the car to a first position with the car roof adjacent to the shaft door at the floor from which the requesting signal originated when that floor is not the lowermost floor, and when the floor is the lowermost floor to a second position above the lowermost floor; instructing the door controller to control the door drive to actively open the door; and switching the engine controller to an inspection mode.
