1.Product introduction:
The HK300SD is composed of the upper part of the 20-ton excavator and AUP220 amphibious undercarriage pontoon. The lower part has fixed lower part and telescopic lower part. The product is widely used in cleaning waterways, lakes, coastlines and other fields. The lower retractable pontoon can reduce the overall width when fully retracted and can be directly transported on a flatbed. When the machine is working, the lower extension can improve the stability and increase the turning moment to improve the turning maneuverability in the swamp. On both sides of the buoy can be added with additional pontoon and spud pile to increase balance and buoyancy, and can work at a water depth of 4 meters.
