Big Hole Diameter DTH Crawler-Mounted Hydraulic Drilling Rig From China

Product Description&Application

DTH engineering driling machine is a kind of submersible electric rotary drilling rig,it is the ideal of bored piles into holes.It can make several groups into drill combination drilling used in underground continuous wall and shaft anti-seepage curtain engineering construction,etc.For silt,clay and gravel layer and weathered shale formation drilling.Widely used in civil ,traffic,water conservancy,electricity,ports and other projects of foundation construction.

Drilling type DTH drilling rig is mainly used for open-pit mine blasting hole chisel,it can also be used for construction ,water conservancy,power engineering,highway,rail and military engineeering and other outdoor drilling operation.It's one of the mainly performation equipment in samll and medium-sized open-pit mine.

DTH drill in under 3000m altitude ,tempreture of 35℃-40℃-climate condition all can use.Usually in 12-15m on the steps of drilling and 60°，75°，90° within the scope of the 150mm diameter inclined or vertical hole.

Main Features

1.Turn-around machine. The structure of newly designed planetary reduction box is more compact than that of straight tooth type reducer with greater reduction ratio, more efficient torque moment transmission, and more smooth operation.
2. Maintenance-free propulsion mechanism. Belongs to a new generation of products,it applied more advanced technology, the propulsion mechanism doesn't need routine oil maintenance.
3. Maintenance-free chassis. Enhanced engineering machinery crawler & box structure crawler frame are sturdy and durable; Maintenance-free thrust wheels, no need for oil injection.
4. Control console. Centralized control console provides convenient operational control of drilling rig; Fast propulsive and lifting operation reduce the auxiliary time and enhance the working efficiency.
5. Drive device.Yuchai 70KW turbocharged engine (Cummins optional) is featured by the strong power and easy maintenance.
6. Drilling arm .Multi-angle elongate functional drilling arm drills larger scope,its sectorial area of drilling work extends 20%.
