FALL ARREST SYSTEM FOR USE WITH A CRANE

摘要

A fall arrest system (1) for use with a crane (39) is presented. The fall arrest system (1) includes a winch (3), a fall arrest unit (4), and a sensor assembly (2). The winch (3) further includes a winch cable (38) extendable and retractable therefrom. The fall arrest unit (4) further includes an arrest cable (28) extendable and retractable therefrom. The sensor assembly (2) further includes a sensor (12). The sensor assembly (2) is disposed between the winch (3) and the fall arrest unit (4). The winch cable (38) is attachable to the arrest cable (28) so that the winch cable (38) pulls the arrest cable (28) across the sensor (12) when the winch cable (38) is retracted in one configuration and the winch cable (38) permits the arrest cable (28) to move away from the sensor (12) when the winch cable (38) is extended in another configuration. The sensor (12) may allow functionality of the crane (39) when the fall arrest system (1) is not in use and may otherwise disable functionality of the crane (39) when the fall arrest system (1) is in use.
