<p>COAL PLANER CONTROL DEVICE A coal planer control device for a coal planer connected to a longwall conveyor having a waste side comprising, a bracket connected to the conveyor, a skid rest pivotally mounted to the bracket for pivotal movement against a mine floor to raise the bracket and tilt the coal planer at a selected angle to a longwall of a coal mine. A lifting mechanism is connected between the bracket and rest for pivotally moving the rest with respect to the bracket and a locking mechanism is connected between the bracket and rest for fixing the position to which the rest was moved by the lifting mechanism. The bracket and rest are pivotally connected to each other substantially along the entire length thereof and both extend substantially along the entire length of the longwall conveyor.</p> |
