Abstract
Official abstract text for this publication.
A suspension work platform hoist system for raising and lowering a work platform is provided. The system incorporates at least one hoist attached to the work platform and in electrical communication with a hoist control system that may have a data transmitter to transmit data to a remote location, a data receiver to receive data from the remote location, and/or a monitoring and diagnostic system to monitor and record at least one of a plurality of operating characteristics of the hoist. The hoist control system may also include a GPS tracking device that transmit a hoist location and may prevent operation of the motor if the hoist location is not in an authorized area of operation. The hoist control system may further include a safety lock out system that requires authentication of an operator prior to the hoist control system causing movement of the hoist system.
