UK-20 Low Profile Dumper Truck
UK-20 Low profile dumper truck is a wheeled transporting equipment designed for underground mining. It works together with LHD underground wheel loader for transporting mine ores and other materials.
UK-20 adopts diesel engine, four wheel drive, rear dump wagon box, central articulation framework with big steering angle and small turning radius.
It is suitable for tunnel section no less than 4mx4m，external turning radius no less than 9m,and slope no more than 14o.
Tunnel temperature -5℃～40℃, Maximum moisture ≤85% (Temerature=25℃)
Evaluation ≤1000m; when the evaluation is more than 1000m please inform us in advance.
Sulfur content in diesel ≤0.2%
