If you could choose between digging 15 feet down into your deposit, using 4 operators with 4 machines OR digging to a depth of 200 feet using 1 operator and 1 machine, of course you’d choose the one machine.

Generally used in smaller operations where budget is a concern.  Less expensive, easier to ship, assemble and relocate (modular design).

 Most common worldwide.  Larger capacities and is designed for more versatility.  Larger pontoon footprint allows for increased digging well, greater stability and more room for onboard equipment.
