Abstract: A hoist apparatus (10) including a rope sensing device (14) for detecting rope fouling events. The rope sensing device (14) includes a lever arm (74) having a first end portion (74g), a second end portion (74h), and a pivot point (74j) located between the first (74g) and second (74h) end portions along the lever arm (74). The lever arm (74) is pivotably mounted to a frame (18) of the hoist apparatus for movement between a sensing position and a fouled position. A follower (78) is connected to the first end portion (74g) and positioned adjacent and spaced from a drum (30) of the hoist apparatus such that rope (38) winds on to the drum spaced from and relative to the follower (78) when the rope sensing device is in the sensing position. A switch actuator (82) is connected to the second end portion (74h) adjacent a switch (86) such that the switch is actuated to a motor stop position when a rope fouling event occurs.
