A standard suspended platform system includes the following components:

Working platform (cradle): The area where workers stand and perform tasks.
Hoist units: Mechanisms on each side of the platform that raise or lower it via wire ropes.
Wire ropes/cables: Provide the suspension and lifting mechanism.
Suspension mechanism: Usually fixed on the roof (e.g., suspension brackets or parapet clamps).
Safety locks: Automatic locking devices that prevent the platform from falling if the hoist fails.
Control box: Used by operators to move the platform up and down.
Counterweights or anchorage: Ensure the system is balanced and secure at the roof level.
Fall arrest systems (harnesses, lifelines): Personal protective equipment for workers.
