Overhead crane trolley positioning

Proper overhead crane positioning in a warehouse or outdoor area is easily solved using a combination of encoders. While precise positioning of the crane’s x- and y-axes can be managed with linear encoders, the z-axis positioning is solved using an absolute multiturn encoder. The KH53 non-contact linear encoder is a rugged solution that determines the absolute position of an overhead crane. It can measure lengths of up to 1.7 kilometers and be used in the harshest environmental conditions, often present in steel warehouses. Additionally, KH53 linear encoders tolerate speeds up to 6.6 m/s.
