Abstract:

A four-bar linkage ladder is used to provide access to the cab of a mobile machine. The ladder is light enough for manual operation and may include a spring assembly, but avoids the need for the electric, pneumatic, or hydraulic actuators of prior art moveable ladders. The ladder swings from bumper height to an ergonomically desirable height for access and egress and allows passage over uneven terrain without ground contact.
