Abstract
A linkage for moving an implement between a working state and a stowed state with respect to a frame of a machine. The linkage includes a carriage, at least one arm assembly, and one or more bump stops. The carriage is configured to support the implement. The arm assembly is coupled to the carriage and is pivotable with respect to the carriage to move the implement to the stowed state. The bump stops are configured to contact an arm, of the arm assembly, in the stowed state of the implement to isolate impact stress away from the frame and onto the linkage.
Claims20
A linkage for moving an implement between a working state and a stowed state with respect to a frame of a machine, the linkage comprising:
- a carriage to support the implement;
- at least one arm assembly coupled to the carriage and pivotable with respect to the carriage to move the implement to the stowed state;
- and
- one or more bump stops configured to contact an arm of the at least one arm assembly in the stowed state of the implement to isolate impact stress away from the frame and onto the linkage;
- wherein the one or more bump stops are coupled to the carriage.
A machine, comprising:
- a frame;
- an implement coupled to the frame;
- a linkage for moving the implement between a working state and a stowed state with respect to the frame, the linkage including:
- a carriage to support the implement;
- a first arm assembly and a second arm assembly, each of the first arm assembly and the second arm assembly being coupled to the carriage and pivotable with respect to the carriage to move the linkage to the stowed state;
- and
- a pair of bump stops configured to be in contact between the carriage and respective arms of the first arm assembly and the second arm assembly to limit, in the stowed state, further movement of the implement towards the stowed state.
