Steeplejacks erect ladders on church spires, industrial chimneys, cooling towers, bell towers, clock towers, or any other high structure.In the UK, steeplejacks now use a belay rope fall-arrest system (similar to the method used by rock climbers) attached to the ladders as they are erected to eliminate solo climbing and greatly reduce the risk of falls from height.
The core item of a fall arrest system, the harness is usually fabricated from rope, braided wire cable, or synthetic webbing. It is attached securely to a stationary object directly by a locking device or indirectly via a rope, cable, or webbing and one or more locking devices.
In a fall, the drum is back driven by the rope as the device slides down the rope; when the drum rotation exceeds a certain angular velocity, it locks off to the frame and the increase in friction induced between the stationary drum and the rope causes the clove hitch to rapidly tighten around the locked drum to arrest the fall.
