Publication number: 20110108294Abstract: A motor grader with an adjustable wheel base is disclosed. The motor grader may include front and rear wheels supporting a chassis and a main frame. A working blade may downwardly depend from the main frame between the front wheels and rear wheels to perform work on the ground below. The motor grader may also provide an adjustable wheel base to allow the center of gravity of the motor grader to better match the work load being addressed. The adjustable wheel base may also provide more swing clearance for the blade relative to the rear wheels, allow for an adjustable articulation angle, and minimize structural loads on the motor grader, particularly during ripping operation. The wheel base may be adjustable by providing structure through which the relative positions of the rear wheels can be altered automatically, manually, and dynamically.Type: ApplicationFiled: November 3, 2010Publication date: May 12, 2011Applicant: CATERPILLAR, INC.Inventors: Norval Thomson, Steven Daniel, Daniel Sergison

Patent number: 7925439Abstract: A method and apparatus for use with a satellite positioning system wherein the receive elements satellite positioning system receive antennas are maintained in an orientation with respect to the positioning system satellites in a way such that the strongest signals can be received from the greatest number of satellites. According to one embodiment, a housing of a positioning antenna is mounted in a gimbaled fashion onto a vehicle, such as an excavator. Such a gimbaled antenna maintains a horizontal orientation relative to a predetermined axis and, as a result, remains in a position to receive signals from positioning system satellites even during instances of high angular deflection of the antenna support, such as may occur during earth-moving operations.Type: GrantFiled: October 19, 2006Date of Patent: April 12, 2011Assignee: Topcon Positioning Systems, Inc.Inventor: Steven Daniel McCain

Patent number: 7857071Abstract: A graphical grade indicator for use in earth moving operations has an improved, variable resolution and a substantially unlimited range. This grade indicator results in a more accurate indication of the position of a cutting blade relative to the desired grade and, as a result, allows a machine operator to more accurately control grading operations. In one embodiment, a graphical grade indicator has a graphical scale with a substantially unlimited range and various indications indicating a desired grade level and at least a first undesirable grade level. When the cutting blade deviates from the desired grade level, a first indication is provided indicating, illustratively, the direction and magnitude of movement of the cutting blade repositioning necessary to achieve the desired grade. The resolution of the graphical scale can be changed in order to provide a desired degree of accuracy in grading operations.Type: GrantFiled: August 5, 2005Date of Patent: December 28, 2010Assignee: Topcon Positioning Systems, Inc.Inventors: Steven Daniel McCain, Richard John Jackson

Patent number: 7689351Abstract: A virtual profilograph is disclosed that can provide measurements indicative of the ride quality of a roadway as the road is being constructed. As a result, a more timely, less costly indication of the ride quality of a roadway is obtained as compared to prior methods. In a first embodiment a Global Navigation Satellite System antenna is attached to a vehicle. When the vehicle travels over a roadway, measurements of the position of the antenna are recorded at different times. A profile of the roadway is created by measuring the elevation of the antenna as a function of the distance traveled from a starting point. In another embodiment, tilt sensors are used to measure the slope of the roadway and the tilt of the vehicle so that a precise orientation of the vehicle and, hence, the contours of the roadway, can be determined.Type: GrantFiled: March 31, 2006Date of Patent: March 30, 2010Assignee: Topcon Positioning Systems, Inc.Inventor: Steven Daniel McCain
