Abstract
A device for accessing an elevated entry position on a machine including an operator position includes a platform, which includes 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, and wherein the ascending and descending proceeds along an axis substantially orthogonal to the step surface. The device may further include a lifting mechanism operatively connected to the machine and the platform.
