Patent number: 8414091Abstract: A crawler has a track tensioning system. The crawler includes a crawler frame having a bottom; at least one drive tumbler supported on the frame; a track made of a plurality of connected track shoes and is wrapped around the drive tumbler so that a plurality of the shoes are in contact with the drive tumbler. The track tensioning system, mounted to the frame, includes a roller engaging the inside surface of the track; and a roller positioning structure attached to the frame that can raise the roller relative to the bottom of the frame to thereby increase the tension of the track.Type: GrantFiled: February 9, 2009Date of Patent: April 9, 2013Assignee: Manitowoc Crane Companies, LLCInventors: David J. Pech, Joel D. Zick, Kenneth J. Porubcansky

Patent number: 8104846Abstract: A crawler has a track connection system. The crawler includes a crawler frame; at least one drive tumbler supported on the frame; a track made of a plurality of track shoes connected in series to produce a track having a first end and second end that can be connected together to form the track into an endless track. The track is wrapped around the frame, with the first and second ends spaced apart but each adjacent a section of the frame. The track connection system is mounted to the frame and includes a mover device connected to the frame; and a track engagement member coupled between the mover device and the track; iii) whereby actuation of the mover device causes the track engagement member to move the track into a position where the first and second ends can be connected.Type: GrantFiled: February 9, 2009Date of Patent: January 31, 2012Assignee: Manitowoc Crane Companies, LLCInventors: Kenneth J. Porubcansky, Joel D. Zick

Patent number: 8075069Abstract: A combination of a drive tumbler and a track includes a track made of a plurality of connected track shoes and a plurality of driven surfaces. The track is wrapped around the drive tumbler so that a plurality of the shoes are in contact with the drive tumbler. The drive tumbler has a plurality of drive surfaces and a circumferential rim surface that includes a plurality of shoe contact surfaces that each contact the inside surface of one of the track shoes that are in contact with the tumbler. The shoe contact surface has a shape such that a line normal to the tangent of the shoe contact surface does not pass through the axis of rotation of the drive tumbler, thereby allowing the shoe contact surfaces on the rim of the drive tumbler to transmit a tractive force to the track. A preferred drive tumbler comprises a center hub and a plurality of individual tooth members connected to the center hub by welds.Type: GrantFiled: February 9, 2009Date of Patent: December 13, 2011Assignee: Manitowoc Crane Companies, LLCInventors: David J.
