A frame casting assembly for a frame of a work machine is disclosed. The frame casting assembly comprises a first end, a middle section, and second end, the first end extending from the middle section and the second end extending from the middle section; the middle section includes: a shaft cutout; a box casting section for managing bending; a first leg and a second leg extending from the middle section; a bridge casting section connecting the first leg and the second leg; and the box casting section and the bridge casting section enclose the shaft cutout.

Frame casting assembly for work machine frame

A work machine includes a frame, a traction system supporting the frame, an arm assembly having a first end and a second end, the first end connected to the frame, an implement connected to the second end, and a linkage connecting the implement to the second end of the arm assembly. The linkage includes a pin-supporting section configured to accept a pin and a linking section attached to the pin-supporting section by a weld. The linking section includes a recess proximate to the weld.

Linkage for arm assembly with reduced weld fatigue

The disclosure is directed to a wheel force transducer mountable on a rotatable wheel in a machine, where the wheel force transducer includes an inner flange configured to be connected to an axle shaft of the machine, an outer flange configured to be connected to the wheel of the machine, a tube connected to the inner flange on one end and connected to the outer flange on the other end; and at least one force sensor mounted on the tube, where at least one force sensor is configured to provide data for at least one of the forces and moments subjected to the wheel.

High load capacity wheel force transducer

A lift arm assembly includes a first arm casting including a first end, a second arm casting including a first end, and a tubular cross member attached to the first arm casting and the second arm casting. The lift arm assembly also includes a first arm tubular member including a first end attached to the first end of the first arm casting. The lift arm assembly further includes a second arm tubular member including a first end attached to the first end of the second arm casting such that the second arm tubular member is generally parallel to the first arm tubular member. At least one of the tubular cross member, the first arm tubular member, or the second arm tubular member has a continuous periphery, a maximum of one seam, and a substantially constant cross-section along substantially an entire length of the respective member.
