Patent number: 9995009Abstract: A self-propelled construction machine includes a machine frame and an operating drum arranged in a drum housing which is open downwards and is closed on both sides by an edge protector which is adjustable in height. A control assembly determines a reference value for the height of the ground surface relative to the machine frame on which the edge protector rests in a floating position, the height of the edge protector relative to the machine frame and the lowering speed of the edge protector. Furthermore, the control assembly is configured such that the height of the edge protector relative to the machine frame is determined at the point in time at which the lowering speed of the edge protector is less than a specified limit value. Preferred embodiments of the machine furthermore detect the edge protector sinking into the ground, and/or prevent the edge protector from digging into the ground.Type: GrantFiled: December 1, 2015Date of Patent: June 12, 2018Assignee: Wirtgen GmbHInventors: Andreas Vogt, Hanjo Held, Christian Berning, Cyrus Barimani

Patent number: 9945194Abstract: The present invention relates generally to a Top Drive Pipe Spinner (TDPS). The TDPS is a tool that allows for the setting of casing without a specialized crew or any additional power source. By employing the weight of the existing top drive to set slips below the casing collar and on the pipe, the TDPS allows one casing to be threaded onto the next in a timely and efficient manner. The casing tongs of the TDPS use passive release weight to release the casing collar from the casing to allow for the successive insertion of another casing section. The top drive spins the TDPS and compresses the unit onto the casing, then lifts the unit and releases the casing when desired.Type: GrantFiled: February 24, 2016Date of Patent: April 17, 2018Inventor: C.
