d. Turn Blockside: Turning can be achieved in two different ways. One of which is by operating the crawler tracks in opposite directions, which causes the BTP to make a quick and highly maneuverable spin about the center of the crawler tracks. The second way is to move only one crawler track and allow the other to drag on the ground. This will provide a turn at a slightly higher radius with an increase of stress and wear on the cat pads. To spin the BTP operate the right crawler control flipper or lever labeled “Crawler Inbye Blockside”, under the section labeled “Tram”, in the “REV” (reverse) direction while simultaneously operating the left crawler control flipper or lever labeled “Crawler Outbye Walkside”, under the section labeled “Tram”, in the “FWD” (forward) direction. To use the second option of dragging the opposing track, just operate one of the crawler control flippers or levers mentioned above. 3. Once the BTP is positioned in a desired location, finish up by following the last steps of the standard BTP start-up procedure (see the “Start-up Procedure” section).
TOWING AND FREE WHEELING – SINGLE TORQUE HUB (2WD) TYPE The following procedure should be followed during towing and freewheeling: 1. Retract all stab shoes, anchoring cylinders, side-slew jacks so that only the crawlers are in contact with the ground. 2. Should the BTP employ a restraining or anchoring device to resist the belt tension, this device must be released so that the unit can be moved. If DBT America provided the restraining device then refer to the section in this manual on “Releasing the Restraining Device” for proper operation or follow the guidelines specified by the mine. The complete restraining device should be completely disconnected. 3. Raise the BTP up as high as possible using only the crawler lift jacks (see the “Crawler Lift Jacks” section). Then place crib blocks or heavy-duty steel stands under the frame so that it is physically held in place as to avoid unexpected cylinder drift or collapse. 4. Shut down the hydraulic power to the BTP (follow the “Shut Down Procedure”). 5. The free wheeling mechanism can be accessed in one of two ways either by crawling under the belt tailpiece or reaching your hands between the tailpiece and crawler frames.
