Dragline Excavator

Dimensional Engineering was contracted to dimensionally control the line boring process for maintenance on the “Walking Mechanism”.

Four 36” dia. bores needed to be aligned over the distance of 20’ with eight smaller bores. The line-Bore had to be aligned precisely to bore each of the holes. With a tolerance of +/- 0.002” along with the size of the crane this project was extreme.
