The purpose of the hanging/rotating gates is to create partitions so that multiple horses can safely train at the same time and independent of eachother.
Hanging/rotating gates motivate horses to walk, provide direction as well as speed. They are designed with the utmost safety standards and offer horses a sufficient range of motion.
KRAFT recommends a minimum distance of 7 m (23') between the gates. The number of partitions depends on the size of the horse walker.

Round horse walker example:
Outer diameter 15 m (49') = 6 horses
Circumference 47 m (154') = 6 × 7.8 m (25.5') partitions

Oval horse walker example:
Outer dimensions 10 × 20 m (33' × 66') = 6 horses
Circumference 51 m (167') = 6 × 8.5m (28') partitions
