SINOMADA Chinese Down The Hole Hammer Drill Rig/Bore Pile Drilling
Machine XR220D Product DescriptionXR220D Rotary Drilling Rig
widely used in boring operation of bored concrete pile in
foundation engineering of highway, railways, bridges, ports, docks
and high-rise buildings. Technical Characteristics:1.The
machine adapt single row rope for main winch to figure out the wear
of steel rope. and extend the life-span. 2.With infrared
camera for observing main winch, Manipulator can observe the state
of steel rope at day and night in cab. 3.Optional
configuration according to customers' requirement Excellent
expansibility. 4.dopting the imported supercharged Imported
engine with European III effluent standard. Meet environmental
rotection and energy conservation. 5.With the hydraulic
pressure system adopted threshold power control and positive flow
control, the system acquired high efficiency and higher energy
conservation. 6.The patented parallelogram articulated
structure actualizes a wider work range. The highly strengthened
box-type steel structure design makes the mast of highly-rigidity
and anticontored, therefore the drill accuracy is
heightened. 7.The complete machine has passed CE certification
of TuV Rheinland group. 8.Standard centralized lubricating
system, allowing easier maintenance. Product
