ABSTRACT:
A reversible alignment system comprising an indicator assembly supported by a mounting assembly that uses conventional reference guides such as a string line or hard surface adjacent the construction site to ensure proper tool orientation for construction vehicles. The indicator assembly comprises a follower, an offset counterweight and a rotary dial supported by a mounting plate. The follower comprises a probe or wheel that moves along the reference guide during vehicle movement. The follower attaches to a linkage bar that connects to a counterweight that keeps the follower against the reference as the vehicle traverses the site. The weight is slightly offset from the follower to dampen vibrations during movement. A pointer secured to the linkage traverses a rotary dial visible to the operator during use. The rotary dial comprises an arcuate gauge with a spaced apart left marker and right marker traversed by the pointer. As the follower moves upwardly or downwardly, the pointer moves correspondingly along the gauge to alert the operator. A mounting plate secures the indicator assembly to the mounting assembly. The mounting assembly comprises a jack connected to a bracket by a standoff. The jack permits the operator to quickly raise or lower the indicator. The mounting assembly can be adjusted at several points so that the follower is properly positioned. The indicator assembly can be easily reversed and moved to the right side of the motor grader by simply flipping the assembly over and reading the pointer against the right side marker.
