Abstract

An apparatus for providing diagnostics of a work device includes an electric crane including an operator cabin and a derrick that supports a lifting magnet; a diagnostic panel disposed proximate the operator cabin; a device that provides one or more operating parameters associated with an operation of the electric crane; and a logic controller in communication with the device and diagnostic panel. The logic controller receives the one or more operating parameter. The diagnostic panel provides one or more quantifiable diagnostics of the electric crane and/or magnet according to the one or more operating parameters received by the PLC. A method is also disclosed.
