Abstract: A guide rail for an elevator system may include at least one rail element that is fastened by at least one fastening means to at least one shaft wall of the elevator system. The at least one rail element may be mounted in a movable manner in relation to at least one shaft wall. The at least one rail element can be moved in relation to the at least one shaft wall such that a space behind the at least one rail element and the shaft wall is accessible for inspection purposes. In some cases, the fastening means includes a hinge by which the rail element can swivel relative to the shaft wall.

Abstract: A transportation device such as an elevator installation, an escalator, or a moving walkway may comprise a person conveying unit and an electromagnetic linear drive for driving the person conveying unit. The electromagnetic linear drive may include a stator segment and a runner element. The runner element can be driven by the force of an electromagnetic field of the stator segment in a first drive direction or in an opposite second drive direction. The runner element is movably mounted on the person conveying unit such that a magnetic resistance in an air gap between the stator segment and the runner element is adjustable depending on a drive force acting between the stator segment and the runner element.
