MEASURING DEVICE FOR MEASURING AN ELEVATOR SHAFT AND USE OF THE MEASURING DEVICE TO MEASURE AN ELEVATOR SHAFT

摘要

A measuring device (1) and the use thereof to measure an elevator shaft (3) are described. The measuring device (1) has two cable-like, elongate guide elements (5), which extend parallel to one another, a measurement platform (7) and a lifting apparatus (9). Each of the guide elements (5) is fixedly attached at an upper retention point (11) and at a lower retention point (13) in the elevator shaft (3) and is tensioned between the upper retention point (11) and the lower retention point (13). The measurement platform (7) has guide apparatuses (15), which laterally support the measurement platform (7) on the guide elements (5) and guide the measurement platform (7) parallel to the guide elements (5) during a shifting movement in a shifting direction (17). The measurement platform (7) has a distance-measuring apparatus (19) in order to measure lateral distances to side walls (21) of the elevator shaft (3). The lifting apparatus (9) is configured to move the measurement platform (7) in the shifting direction (17).
