Overhead crane gear position

Positioning overhead cranes can be accomplished 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 AFS/AFM60 encoder is a rugged solution that determines the absolute position of the overhead crane’s gears. The absolute encoder measures infinite lengths by counting rotations and is used in the harshest environmental conditions, which are often present in outdoor areas of steel plants.
