Guardrail assembly for work machine

A work machine comprising:

• a frame;
• an operator platform coupled to the frame, the operator platform defining a major surface;
• and
• a guardrail assembly for the operator platform, the guardrail assembly including:
• a handrail removably coupled to the operator platform, the handrail including a pair of first members spaced apart from each other and a second member coupled to and extending orthogonally between the pair of first members, the handrail defining a height orthogonal to the major surface, wherein the handrail is movable between an extended position and a retracted position relative to the major surface of the operator platform, wherein, in the extended position, at least half of the height of the handrail is disposed above the major surface of the operator platform, and wherein in the retracted position, at least half of the height of the handrail is disposed below the major surface of the operator platform;
• a pair of handrail locking mechanisms removably coupling the handrail to the operator platform, wherein each handrail locking mechanism is configured to engage with the handrail to dispose the handrail in the extended position, and wherein each handrail locking mechanism is configured to disengage from the handrail to dispose the handrail in the retracted position;
• a midrail removably coupled to each first member at corresponding opposing ends of the midrail, wherein the midrail is substantially parallel to the second member of the handrail;
• and
• a pair of midrail locking mechanisms removably coupling the midrail to each first member at corresponding opposing ends of the midrail, wherein, when the handrail is in the extended position, the pair of midrail locking mechanisms engage the midrail with corresponding first members of the handrail to dispose the midrail at a desired height along the pair of first members of the handrail, and wherein the pair of midrail locking mechanisms disengage the midrail from corresponding first members of the handrail to dispose the handrail in the retracted position.
