  • Interlock arrangement for powered devices
    Patent number: 9840819
    Abstract: Embodiments of the invention provide an interlock arrangement with a blocking feature and a locking feature secured to an interlock member. The interlock member can move between first and second interlock orientations. With the interlock member in the first interlock orientation, the blocking feature can prevent attachment of a power conduit to a power connection, such that the motor is not enabled to power a powered device, and the first locking feature can allow a first gate to open in order to provide access to the powered device. With the interlock member in the second interlock orientation, the blocking feature can allow attachment of the power conduit to the power connection, such that the motor is enabled to power the powered device, and the first locking feature can prevent the first gate from opening such that the first gate obstructs access to the powered device.
