TR300D Concrete Equipment Rotary Drilling Rig for Bore Pile Drilling With Good Price
The TR300D rotary drilling righas an operating weight of approx 97 ton. It is specially designed to suit the following applications:
a. Rotary drilling;
b. Drilling cased boreholes(installation of casing by rotary drive);
c. Drilling with telescopic friction or interlocking kelly bar-standard Supply;
d. Drilling cased bore piles(casing driven by rotary head or optionally by casing oscillation);
e. CFA Piles by means of continue auger;
f. Either crowd winch system or hydraulic crowd cylinder system;
g. Displacement piles;
h. Soil-mixing.
TR300D rotary drilling rig ismainly used in the construction oflarge bridges, elevated railway,larger aperture and deep pileconstruction, and this machine can match with various drilling tools for hole operation, such as auger or bucket, core barrel, cleaning bucket etc.
