• Cuts slots for the retrofitting of Dowel Bars in jointed concrete movement.  The PC490 cuts all 6 slots at once, using 2 cutting heads (one for each wheel path).
• Due to the long stroke cylinder on each head, the PC490 can be used to cut slots on straight or skewed transverse joints, or random cracks.  Each head can be operated simultaneously or individually.  After the cutting parameters are set, the cutting process is done automatically through PLC-controlled hydraulic circuitry.
• In the automatic mode, once the operator has the machine aligned, he simply pushes the on button to begin the cutting cycle.  When the slots are complete, the blades return to their preset starting position and the operator moves the machine to the next joint.  The auto-mode greatly enhances the productivity and extends blade life.  Production rates of more than 100 slots per hour are not uncommon.
• The heads are hydraulically driven.  Each head is closed loop powered by a Deutz liquid cooled diesel engine.  Each engine develops 258 HP at 2300 rpm.  Auziliary pumps mounted on each engine provide oil flow for all of the machine functions.
• Machine ground drive is by joystick control to 4 wheel drive hydrostatic powered toque hubs with wet disc brakes.  Wheels are solid rubber 22" x 10" x 16".  Travel speed is approximately 130 fpm.  A steering wheel controls the front wheels.  Rear wheels steer (when needed is by job-switch).

Special configuration diamond blades are used.  Normal blade diameter is 20" for 6-inch deep cut.  The machine can accept up to 24" diameter blades.
