Apparatus and method for aligning guide rails and landing doors in an elevator shaft

An apparatus configured to align car guide rails and landing doors in an elevator shaft, the elevator shaft extending in a first direction from at least a first floor to at least a second floor, the car guide rails including a first car guide rail and a second car guide rail at opposite side walls of the elevator shaft, the apparatus comprising:

• a frame;
• at least two pairs of actuators including a first pair of actuators positionable on a first side of the frame, and a second pair of actuators positionable on a second side of the frame, each actuator of the first pair of actuators and each actuator of the second pair of actuators including a support arm configured to move in a second direction, the frame configured to support the first pair of actuators and the second pair of actuators with support mechanisms, the support mechanisms configured to move in a third direction perpendicular to the second direction, the second direction and the third direction configured to extend in a coinciding plane or in parallel planes, the second direction and the third direction being different from the first direction;
• a first grip supported on the first side of the frame and a second grip supported on the second side of the frame, the first grip configured to attach to the first car guide rail and the second grip-configured to attach to the second car guide rail;
• and
• a measuring device attached to the frame in a vicinity of the first grip and the second grip, the measuring device configured to determine a position of the apparatus in the elevator shaft.
