Patent number: 11591199Abstract: A lift device includes a base, an arm, a tractive element, and a steering actuator. The arm has a base end coupled to the base and a tractive element end. The arm includes a steering actuator interface positioned along an exterior surface of the arm. The tractive element is coupled to the tractive element end. The steering actuator has a first end coupled to the steering actuator interface and an opposing second end coupled to the tractive element. The arm includes a plate extending from the exterior surface of the arm at an upward angle and past the steering actuator.Type: GrantFiled: October 23, 2020Date of Patent: February 28, 2023Assignee: Oshkosh CorporationInventors: Jesse Holmes, Constantin B. Marinoiu, Stephen Z. Smith, Eric Hackenberg, Jihong Hao, Harish Sivasubramanian, Marcel Amsallen

Publication number: 20220204332Abstract: A mobile elevating work platform includes a chassis, a slew bearing, a turntable, a lift system, and a turntable leveling system. The turntable leveling system is positioned above the slew bearing and supports the lift system. The turntable leveling system includes a baseplate, a bracket, a first actuator, and a second actuator. The baseplate extends above the slew bearing. The bracket is rotatably coupled to the baseplate and is configured to tilt relative to the baseplate about an axis extending parallel with the baseplate. The first actuator is positioned on a first side of the bracket and the second actuator is positioned on a second side of the bracket.Type: ApplicationFiled: December 28, 2021Publication date: June 30, 2022Applicant: Oshkosh CorporationInventors: Wenton S. Miller, Eric Hackenberg

Publication number: 20210039934Abstract: A vehicle includes a chassis, a first actuator coupled to the chassis, a second actuator coupled to the chassis, a third actuator coupled to the chassis, a fourth actuator coupled to the chassis, and a fluid circuit. The fluid circuit is configured to facilitate selectively fluidly coupling the first actuator, the second actuator, the third actuator, and the fourth actuator in a plurality of different configuration. In each of the plurality of different configurations, two of the first actuator, the second actuator, the third actuator, and the fourth actuator are fluidly coupled together while the other two of the first actuator, the second actuator, the third actuator, and the fourth actuator are fluidly decoupled.Type: ApplicationFiled: October 23, 2020Publication date: February 11, 2021Applicant: Oshkosh CorporationInventors: Eric Hackenberg, Jihong Hao, Harish Sivasubramanian, Marcel Amsallen

Patent number: 10858231Abstract: A lift device includes a base, an arm, a drive actuator, a tractive element, and a steering actuator. The arm has a base end coupled to the base and a tractive element end. The arm includes a steering actuator interface positioned along an exterior surface of the arm. The drive actuator is pivotally coupled to the tractive element end of the arm. The tractive element is coupled to the drive actuator. The steering actuator has a first end coupled to the steering actuator interface and an opposing second end coupled to the drive actuator. The arm includes a plate extending forward of the exterior surface of the arm and past the steering actuator.Type: GrantFiled: November 4, 2019Date of Patent: December 8, 2020Assignee: Oshkosh CorporationInventors: Jesse Holmes, Constantin B. Marinoiu, Stephen Z. Smith, Eric Hackenberg, Jihong Hao, Harish Sivasubramanian, Marcel Amsallen
