Patent number: 8672063Abstract: A motorized chain roller includes a frame, a roller chain assembly movably disposed within the frame, a first sprocket that engages the roller chain assembly to apply a transmission force to the roller chain assembly, at least one motor coupled to the frame and configured to transmit a rotational force to the first sprocket, and a load-bearing member coupled to and located within the frame. The roller chain assembly includes a plurality of interconnected cylindrical rolls arranged in a continuous series. Each of the cylindrical rolls has an axis or rotation. The roller chain assembly engages the load-bearing member to cause movement between the roller chain assembly and the load-bearing member perpendicular to the axes of rotation.Type: GrantFiled: March 9, 2012Date of Patent: March 18, 2014Assignee: Hilman, IncorporatedInventors: Darth Christopher Fitch, Christopher Taylor Hill

Publication number: 20140048343Abstract: A multi-axis articulating crawler includes a turntable assembly having a turntable, a first main beam rotatably coupled to a first side of the turntable assembly and a second main beam rotatably coupled to a second side of the turntable assembly. First and second track assemblies are rotatably coupled to the first main beam, and third and fourth track assemblies are rotatably coupled to the second main beam. The axes of rotation of the first, second, third and fourth track assemblies are perpendicular to the axis of rotation of the first and second arms. The longitudinal axes of the first and third track assemblies are on the same line and the longitudinal axes of the second and fourth track assemblies are on the same line. The track assemblies are independently driven to maneuver the crawler.Type: ApplicationFiled: August 17, 2012Publication date: February 20, 2014Applicant: HILMAN, INCORPORATEDInventors: Darth Christopher Fitch, Christopher Taylor Hill

Patent number: 7275908Abstract: A roller mechanism for transporting loads over a surface, the roller mechanism including a body, at least one roller assembly that permits the body to move in at least one translational direction, the roller assembly being rotatably connected to the body, and a lifting mechanism attached to the body such that the body is selectively rotatable relative to the lifting mechanism, wherein the lifting mechanism can be operated to lift the roller assemblies out of contact with the surface.Type: GrantFiled: January 21, 2004Date of Patent: October 2, 2007Assignee: Hilman, IncorporatedInventors: David A. Hill, Jeffrey A. Kinsberg
