The stronger elevator makes the 623H capable of far more than finish work. Material Handling The elevator lifts material off of the cutting edge and carries it to the top of the elevator and then dumps the material into the bowl. Blending the material helps eliminate voids in the bowl for consistent payloads and uneven loading. Closed Loop Elevator Hydraulic System The 623H elevator power has been increased by a new variable displacement piston pump and fixed displacement motor in a closed-loop circuit. The increased power enables the operator to take deeper cuts and load in a shorter...
