US 2022/0018099 A1 · APPARATUSES AND METHODS FOR MEASURING SADDLE LINKAGE POSITION OF A MOTOR GRADER

Abstract

Graders and methods of operation thereof are disclosed herein. A grader includes a chassis, a saddle linkage, and a motion measurement system. The saddle linkage is supported for movement relative to the chassis and includes a mount movably coupled to the chassis, first and second arms each movably coupled to the mount, and a crossbar movably coupled to each of the first and second arms. The mount has a lock pin aperture, each of the first and second arms has a locking hole, and the crossbar has a plurality of locking holes. The lock pin aperture may be aligned with one locking hole of the first arm, the second arm, or the crossbar to position the saddle linkage in use of the grader. The motion measurement system is coupled to the saddle linkage and configured to measure movement or position of one or more components of the grader in use thereof.

Dependent claims

A work machine comprising:

a chassis;
a linkage supported for movement relative to the chassis, wherein the linkage has a lock pin aperture and a plurality of locking holes, and wherein the lock pin aperture may be aligned with one of the plurality of locking holes to position the linkage in use of the work machine;
and
a motion measurement system coupled to the linkage, wherein the motion measurement system includes at least one sensor mounted in close proximity to the lock pin aperture, at least one indicator mounted in close proximity to at least one of the plurality of locking holes, and a controller coupled to the at least one sensor that is configured to receive sensor input from the at least one sensor indicative of one or more characteristics of the at least one indicator and to determine a positional state of the linkage based on the sensor input.
