HK300SD swamp excavator marshland excavator dredging excavator amphibious excavator

1.ISUZU engine or CUMMINS engine 2.kawasaki or paike hydraulic parts 3.can design as customers' requirements

1.Tracked pontoon structure ensures low ground pressure so that it can travel and work on swamp and soft areas, it can also be towed to move forward on water.

2.Big torque travelling devices ensure strong driving force when turning and climbin.

3.Big circular arc structure on both ends of pontoon reduces traveling resistance.

 

4.High capacity of fuel tank greatly increases time interval of fueling.

5.It takes less than one hour to assemble and dismantle the machine; it is easy to be transported.
