Abstract
A linkage mechanism associated with a handrail assembly of a machine is provided. The handrail assembly is coupled to an operator platform. The handrail assembly includes a first handrail member coupled to the frame. The linkage mechanism connects the first handrail member to the frame such that the first handrail member can be pivotally moved between an extended position and a retracted position. The linkage mechanism includes a first bracket and a pair of linkage members. The first bracket is coupled to the frame. The pair of linkage members pivotally connect the first bracket with the first handrail member. The first bracket, the pair of linkage members and the first handrail member together form a four-bar linkage. Further, a spring biased latching mechanism is configured to retain the handrail assembly in a retracted or an extended position.
