UNDERSTRUCTURE

Welded Structural Tubing Supports incorporate pin connections. Hand Winch folds Forward Support under Conveyor Truss for travel. A Crane (or similar machine) is required to change Model 575 from travel to operating position (and visa versa). A Tail Pivot Assembly provides for anchor to foundation, as well as radial operation Pins to Conveyor for the exclusive MARCO. "Quad Ram" Hydraulic Understructure is an available option for raising and lowering.

AXLE AND WHEELS

Telescoping "Box Section" Main Axle, with independent Bogie Axles and Tandem Wheels provide lower "load per Axle" ratings and excellent off-road tracking. Tandem Pneumatics (4 tires) offer safe 20 MPH rating.   Travel width - 10' - 5" (11" with optional Brakes).
Operating width - 15" - 0".

RETRACTABLE LANDING GEAR (OPTIONAL)
