Abstract: A mobile transport device and a method for introducing an installation frame into a shaft, in particular an elevator shaft, are used for transporting an installation frame and for introducing the installation frame into the shaft. The installation frame has a base frame and a bearing frame on which the installation frame is supported from above. The transport device additionally has a fixing device arranged on the base frame for fixing the base frame to a shaft opening of a shaft wall of the shaft and for preventing the transport device from tilting. The bearing frame is supported by the base frame and is movable in the horizontal direction relative to the base frame such that, when the base frame is arranged outside of the shaft, the bearing frame, and thus also the installation frame, can be moved into the shaft from outside the shaft through the shaft opening.

Abstract: A car arrangement includes: a first car and a second car arranged one above the other in a car frame; wherein at least the first car is displaceable along the car frame in the direction of a vertical axis by a spindle drive; wherein the spindle drive includes a spindle and a drive unit; wherein the spindle drive is guided through a cutout in a support structure of the car frame, and the drive unit has a housing with a fastening flange fastening the housing to the support structure; and wherein the housing has first and second positions in relation to the cutout, the fastening flange exposing the cutout in the first position so the spindle drive can be guided through the cutout in the direction of the vertical axis, and the fastening flange projects beyond an outer edge of the cutout in the second position.

Abstract: An installation device for use in an elevator shaft includes a carrier that extends in a carrier direction, the carrier having a first carrier end and a second carrier end, a support element that is pivotably arranged on the first carrier end and a receiving device for receiving a displacement device by which installation material can be displaced in the elevator shaft. The receiving device is supported on the carrier via an adjustable support device such that an angle between a support plane, in which plane a support surface of the receiving device extends, and the carrier direction of the carrier can be changed.
