Publication number: 20230383501Abstract: A machine may include a body, a boom link, a swing casting, and a boom. The boom and the swing casting may be configured to rotate horizontally about an axis through the boom link. The machine may further include a mounting bracket fixedly connected to the swing casting, a position sensor fixedly connected to the boom link, a first link fixedly connected at a first end to the position sensor and configured to rotate about an axis through a rotary element, and a second link fixedly connected at a first end to the mounting bracket and at a second end to a second end of the first link. The first link and the second link may be configured to rotate horizontally with horizontal rotation of the boom and the swing casting and to transfer the horizontal rotation of the boom and the swing casting to the rotary element.Type: ApplicationFiled: May 25, 2022Publication date: November 30, 2023Applicant: Caterpillar Inc.Inventors: Vincent Adam ARMSTRONG, Joshua D. CALLAWAY, Christopher Erik BRIGHT, Benjamin J. TERRY, Michael C. LAYKO

Publication number: 20140317967Abstract: An excavator has an undercarriage assembly and a turret assembly rotatable relative to the undercarriage assembly. The undercarriage assembly has an undercarriage implement support that may pivot about a lift axis. An undercarriage coupler is coupled to the undercarriage support and includes an undercarriage coupler interface that is configure to operably engage an undercarriage implement interface provide on an undercarriage implement. The turret assembly also carries a turret implement, and therefore the excavator may simultaneously employ both the undercarriage implement and the turret implement.Type: ApplicationFiled: April 24, 2013Publication date: October 30, 2014Applicant: Caterpillar Inc.Inventors: Jeffrey M. Parker, Michael C. Layko, Justin D. Speichinger

Patent number: 8573336Abstract: A machine is provided. The machine has a forward direction of travel and includes a frame, at least one lift arm, a first torsion axle assembly, an undercarriage, and an endless track. The lift arm is pivotally attached to the frame. The first torsion axle assembly is attached to the frame and includes a first torsion arm, a first torsion shaft, and a first axle, with the first torsion shaft and the first axle extending from the first torsion arm. The undercarriage is attached to the first torsion axle assembly and the endless track encircles the undercarriage. One of the first torsion shaft and the first axle is attached to the frame and the other of the first torsion shaft and the first axle is attached to the undercarriage. The first torsion arm extends upward from the frame at an angle between 90 and 180 degrees from the forward direction of travel.Type: GrantFiled: June 1, 2011Date of Patent: November 5, 2013Assignee: Caterpillar Inc.Inventors: Mylvaganam Arulraja, Michael S. Freberg, Leslie L. Weaver, Jr., Michael C. Layko, Jeffrey M. Parker, Michael Bottom

Patent number: 7578651Abstract: A method of lifting a boom assembly for a machine along a lift path is provided. The machine has a work implement coupled to the boom assembly. The method includes initially moving the work implement vertically from a lowered position to a first intermediate position forward of the lowered position. The method also includes subsequently moving the work implement vertically from the first intermediate position along a slightly rearwardly inclined direction to a second intermediate position rearward of the first intermediate position. The method also includes subsequently moving the work implement vertically from the second intermediate position along a slightly forwardly inclined direction to a third intermediate position forward of the second intermediate position. The method also includes finally moving the work implement vertically from the third intermediate position along a slightly rearward inclined direction to a final position rearward of the first, second, and third intermediate positions.Type: GrantFiled: December 21, 2006Date of Patent: August 25, 2009Assignee: Caterpillar S.A.R.L.Inventors: Michael C. Layko, Jeffrey M. Parker
