Abstract
The safe operation of crane systems is of great importance for operators, as this involves availability, operational safety and therefore cost risks. The legal regulations and technical rules ensure that a lot of attention is paid to the functional testing of the devices. The general conditions, with a focus on the crane runways or running rails, are often checked with less concentration. The specified manufacturer tolerances of the tracking mechanism for wheels and tracking rollers are no longer checked regularly and carefully. The driving properties and service life of a crane system are heavily dependent on the accuracy of the rails and the alignment of the track guidance elements. The crane and crane track interact with each other to determine the vertical and horizontal forces that actually occur as a result of disturbance variables. Exceeding tolerance limit values in accordance with the information in VDI 3576 not only affects the driving behavior and thus the optimal availability of the system, but also represents a risk for people and machines. This standard presents measuring devices and aids as well as measuring methods that are for Measurement of rail and crane systems can be used.
