Pontoon Construction:
High Strength, Low Alloy, Weathering Cor-Ten plate steel is used in the fabrication of the Wilco pontoons. Cor-Ten steel has 5 to 8 times the atmospheric corrosion resistance and 20% more tensile strength than similar size A36 structural plate steel. Each pontoon has 5 bulkheads, providing 6 independent watertight compartments. The bottoms of the pontoons are reinforced for rough terrain operation.
Drive System:
Power for the pontoon tracks is provided by the excavator’s diesel engine and main hydraulic pumps through a hydraulic swivel. Hydraulic travel motors and brakes are mated to sealed planetary final drives to provide independent power to each pontoon track. Standard excavator travel controls are used.
Drive Chain:
Engineering class 3.067 inch pitch, high strength offset side bar drive chain is used to transfer power from the two stage planetary final drive gear boxes to the drive shaft sprocket on each track.
Track Chain:
Three strands of heavy-duty 4-inch pitch marsh buggie track chain per pontoon. The hardened track chain rollers run in pontoon channels lined with an abrasive resistant wear bar. Drive and idler shaft sprockets are flame hardened to match the hardness of the track chain rollers.
Track Cleats:
Specially designed marine grade, extruded 6061-T6 aluminum alloy double grouser cleats with 2 HDMP wear pads are capable of supporting the pontoon and its payload. |
