Abstract:
1. A device for accessing an elevated entry position on a machine including an operator position, the device comprising: a platform including a step surface, configured to ascend and descend between a base position and the elevated entry position, wherein the platform remains within an existing envelope of the machine throughout ascent, descent, and storage of the platform; a lifting mechanism operatively connected to the machine and coupled to a side of the platform such that the platform projects as a cantilever from the lifting mechanism; and a latching mechanism including a hydraulic latch actuator configured to close when the platform reaches the elevated position, further including one or controllers associated with the lifting mechanism and including a communicative connection to at least one sensing system configured to sense an operational state of the machine, the operational state including at least one of whether the machine is in motion or whether a parking brake of the machine is engaged, the latching mechanism is communicatively connected to said one or more controllers, wherein the latching mechanism is configured to communicate a positional state of the platform to the controller.
