Method and assembly device for carrying out an installation process in an elevator shaft of an elevator system

A mounting device for carrying out an installation operation in an elevator shaft of an elevator system, comprising:

• a carrier component;
• a mechatronic installation component held on the carrier component;
• wherein the carrier component is displaceable, in a displacement phase of the installation operation, relative to the elevator shaft and can be positioned at different heights within the elevator shaft;
• wherein, in a mounting phase of the installation operation, the installation component can carry out a mounting step at least partially automatically to remove a mounting means from a magazine component disposed on the carrier component and to install the mounting means at a shaft wall of the elevator shaft;
• wherein the carrier component includes a magazine receiving device movable between a mounting position and a loading position for receiving the magazine component;
• wherein, in the mounting position, the mounting means can be removed from the magazine component disposed on the magazine receiving device by the installation component and the carrier component can be displaced in the elevator shaft;
• and
• wherein, before the mounting phase and in the loading position, a stocked magazine component can be disposed on the magazine receiving device via an accessible door cutout of the elevator shaft and used as the magazine component during the mounting phase.
