Pontoon
Construction
High-Strength, Low Alloy, Weathering Cor-Ten plate steel isused
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 4 bulkheads, providing 5 independent
watertight compartments. The bottoms of the pontoons are reinforced
for rough terrain operations.
Carbody
Wilco custom designed flanged center car body making assembly
and disassembly faster and easier.
Track
Shoes
Specially designed marine grade, extruded 6061-T6 aluminum alloy
cleats with 2 HDMP wear pads are capable of supporting the pontoon
and its payload.
Track
Chains
Three strands of specially designed, heavy-duty, 4 inch pitch
marsh buggy track chain are installed on each 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.
Drive
Chains
Engineering class 3.067, high strength, heavy-duty offset drive
chain is used to transfer power from the two stage planetary
final drive gear boxes to the drive shaft sprocket on each track.
Hydrostatic
Drive
Power for the pontoon tracks is provided by the 320D excavator’s
diesel engine and main hydraulic pumps through a 320D hydraulic
swivel. Cat® 320D travel motors and brakes are mated to the
sealed planetary final drives to provide independent power to
each pontoon track. Standard excavator travel controls are used.
