Abstract
A hoist system may include a rotatable shaft, a spool, and a lifting line. The lifting line may be configured to couple to a load. Further, the lifting line may be configured to be wrapped and unwrapped relative to the spool to adjust a position of the load. Additionally, when the shaft rotates, the spool may be configured to rotate together with the shaft and simultaneously slide along the shaft.
