PLATFORM AND SHIELD FOR IMPLEMENT

摘要

The innermost end of a platform is pivotally connected to an implement adjacent upright sidewall structure which supports moving parts that normally are shielded but from time to time require inspection and service. The platform is rockable between a horizontal access position and a vertical shielding position. A door or shield is connected to the outer end of the platform, and four-bar linkage structure maintains the door in an upright position to provide a railed work station for the operator when the platform is in the horizontal position and a generally continuous upright shield structure when the platform is in the vertical position. The four-bar linkage structure includes upper and lower links which contact each other when the platform is horizontal to support the platform without need for obstructive braces or the like.
