Abstract
A compact work machine, such as a compact track loader and/or a compact utility loader, which can carry and operate a wide range of attachments while maintaining a reduced operating footprint.
Claims20
A work machine comprising:
- a frame presenting an interior compartment and comprising a bottom portion and a rearward portion extending vertically from said bottom portion;
- an operator cab presenting an interior space and including a back side hingedly connected to said rearward portion of the frame at a cab pivot point so that said cab can be selectively positioned in a lowered position and a raised position;
- and
- an electrohydraulic actuator secured to said rearward portion of the frame at a position rearward of the cab pivot point and to said back side of said cab at a position between the cab pivot point and a bottom of the cab, wherein the electrohydraulic actuator is configured to shift said cab between the lowered position and the raised position.

A method of providing access to components of a work machine, the method comprising:
- electrically connecting a switch positioned outside an interior space of a cab of the work machine to an energy storage device connector positioned within an interior compartment defined by a frame of the work machine, wherein said cab is hingedly connected to said frame at a cab pivot point so that said cab shifts between a lowered position and a raised position;
- and
- electrically connecting to said switch an electrohydraulic actuator that is secured to a rearward portion of said frame and to a back side of said cab so that said electrohydraulic actuator can shift said cab to the raised position,
- wherein the electrohydraulic actuator is hingedly secured to said rearward portion of the frame at a position rearward of the cab pivot point and to said back side of said cab at a position between the cab pivot point and a bottom of the cab.

- an operator cab presenting an interior space and including a back side hingedly connected to said rearward portion of the frame at a cab pivot point so that said cab can be selectively positioned in a lowered position and a raised position;
- an energy storage device connector in said interior compartment;
- an engine positioned in said interior compartment;
- and
- an electrohydraulic actuator secured to said rearward portion of the frame at a position rearward of the cab pivot point and to said back side of said cab at a position between the cab pivot point and a bottom of the cab, wherein the electrohydraulic actuator is configured to shift said cab between the lowered position and the raised position,
- wherein said electrohydraulic actuator is electrically connected to said energy storage device connector, such that said electrohydraulic actuator is operable without said engine operating.
