Abstract: A frame for a construction machine includes a pair of side truss members extending along a longitudinal axis of the construction machine. Each side truss member defines one or more first cut-outs, an axle opening for receiving a portion of an axle assembly of the construction machine, and a first through-aperture. The first through-aperture is adapted to at least partially receive a fastening element for coupling the axle assembly with a corresponding side truss member. The frame also includes a first lateral truss member extending between the pair of side truss members and defining at least one second cut-out. The frame further includes a second lateral truss member extending between the pair of side truss members and defining at least one third cut-out. The pair of side truss members, the first lateral truss member, and the second lateral truss member together define a hollow space of the frame.

Abstract: A rear frame for a motor grader includes a pair of arms that are disposed equidistantly from a mid-plane. Each arm has a front portion, a rear portion, and a mid-portion located between the front and rear portions. The front portion of each arm is configured to pivotally couple with a front frame of the motor grader. The rear frame also includes a ripper mounting arrangement, a bumper, and a torque resisting member. The ripper mounting arrangement is located at a rear end of the rear portion of each arm. The bumper is laterally disposed with respect to the mid-plane and rigidly attached to a position on the rear portion of each arm located adjacent the rear end of the rear portion of each arm. The torque resisting member is laterally disposed with respect to the mid-plane and rigidly attached to the mid-portion of each arm.

Abstract: A structurally integrated fuel tank and method of assembling is disclosed. The fuel tank may comprise a body and a neck disposed on the body. The neck may be configured to be coupled to an arm of a front frame of a machine. The body may comprise a cover, an endwall and a base. The cover includes a cover hitch that defines an upper pivot bore centered about a pivot axis. The upper pivot bore is configured to receive a pivot fastener about which the fuel tank is pivotable. The endwall may be disposed below and coupled to the cover. The base may be coupled to the endwall, and may include a lower hitch that extends outward and away from the endwall. The neck and the body together define a chamber configured to store fuel. The cover is a top of such chamber.
