LOW PROFILE MINING MACHINE Abstract of the Disclosure - To maintain the lowest possible machine profile be- tween the bottoms of the crawler treads and the top of the turret, the boom of the machine and boom lifting cylinders are cantilevered forwardly of the turret and depressed to lie as closely as possible to the underlying gathering head of the machine without clogging the throat of the machine and/or inter- fering with the operation of the gathering arms. The boom pivot and boom lift cylinders are disposed ahead of the crawler treads and the connections of the boom lift cylinders with the turret are forwardly of the highest part of the gathering head. This geometry renders it possible to significantly lower the eleva- tion of the machine turret on which the boom is mounted for sluing or swinging movement and thus minimize the total height or profile of the mining machine.
