Abstract
A walkway assembly for a work machine includes a walkway unit pivotally coupled to the work machine. The walkway assembly also includes a system for assisting a movement of the walkway unit from a deployed position to a stowed position. The at least one coil spring is coupled to the walkway unit at one end thereof. The at least one coil spring is coupled to a portion of the work machine at another end thereof. The at least one coil spring is adapted to urge the walkway unit to the stowed position from the deployed position, based on potential energy stored within the at least one coil spring.
Claims20
A walkway assembly for a work machine, the walkway assembly comprising:
- a walkway unit pivotally coupled to the work machine;
- and
- a system for assisting a movement of the walkway unit from a deployed position to a stowed position, the system including:
- at least one coil spring, wherein the at least one coil spring is coupled to the walkway unit at one end thereof, wherein the at least one coil spring is coupled to a portion of the work machine at another end thereof, and wherein the at least one coil spring is adapted to urge the walkway unit to the stowed position from the deployed position, based on potential energy stored within the at least one coil spring.
A walkway assembly for a work machine, the walkway assembly comprising:
- a walkway unit pivotally coupled to the work machine;
- and
- a system for assisting a movement of the walkway unit from a deployed position to a stowed position, the system including at least one winch, wherein the at least one winch includes:
- a drum having an axis, the drum being rotatable about the axis;
- and
- an elongate, flexible member at least partially wound around the drum, wherein the flexible member is coupled to the walkway unit at one end thereof, wherein the flexible member is coupled to the drum at another end thereof, and wherein the flexible member is adapted to move the walkway unit to the stowed position from the deployed position, based on a rotation of the drum.
A walkway assembly for a work machine, the walkway assembly comprising:
- a walkway unit pivotally coupled to the work machine;
- and
- a system for assisting a movement of the walkway unit from a deployed position to a stowed position, the system including:
- at least one actuating device, wherein the at least one actuating device is coupled to the walkway unit at one end thereof, wherein the at least one actuating device is coupled to a portion of the work machine at another end thereof, wherein the at least one actuating device is adapted to move the walkway unit to the stowed position from the deployed position, based on an actuation of the at least one actuating device, and wherein the at least one actuating device includes at least one of a strut and an actuator.
