Illinois Rope Operations Practice Test

The key idea is a metal device that grips rope using a camming action. A hard cam is designed with a cam surface that, when the rope is loaded, presses against another surface to pinch or wedge the rope and create a tight, secure grip through friction. This camming mechanism is what differentiates it from other devices.

For context, a cam follower is simply a component that rides on a cam’s profile and doesn’t itself clamp or grip rope. A rope clutch relies on general friction to hold rope, typically without a cam-shaped actuator. An auto cam implies some automatic locking behavior, but the device described here is specifically defined by its camming action to grip rope, which is characteristic of a hard cam.
