Patent number: 8348073Abstract: A mobile lift crane includes a carbody made from two side members and two end cross members connected to each other with a carbody connection that can be disconnected such that the side members and end cross members can be individually transported between job sites and reassembled at a new job site. Preferably the two side members are interchangeable with each other when making the carbody, and the two end cross members are also interchangeable with each other. Further, each of the side members and end cross members preferably has a section of a roller path and section of a ring gear attached to them while being transported and assembled.Type: GrantFiled: September 16, 2009Date of Patent: January 8, 2013Assignee: Manitowoc Crane Companies, LLCInventors: Bronson E. Foust, David J. Pech

Patent number: 7997432Abstract: A mobile lift crane includes a carbody and at least four crawlers attached to the carbody, each crawler having a crawler frame attached to the carbody by a trunnion having an axis. The crawler frame is attached to the carbody so as to be able to pivot with respect to the carbody about the axis of the trunnion. The crane also includes a rotating bed rotatably connected to the carbody such that the rotating bed can swing with respect to the crawlers and a boom pivotally mounted on a front portion of the rotating bed. A linear actuator is connected between the crawler frame and the carbody and extends through the trunnion. The linear actuator is part of a self attachment mechanism. The trunnion includes a tubular member with a longitudinal axis, a first end configured for connection to the crane carbody and a second end configured for connection to the crawler frame. At least one of the ends is configured to allow rotational movement of the crawler frame relative to the carbody about the longitudinal axis.Type: GrantFiled: September 16, 2009Date of Patent: August 16, 2011Assignee: Manitowoc Crane Companies, LLCInventors: Kenneth J.
