HYDX-6A Full Hydraulic Drilling Rig
I. Description
HYDX-6A full hydraulic drilling rig is a thoroughly new type of drilling rig developed on the basis of advanced techniques in the world. HYDX-6 is reasonable in design, excellent in performance, easy for operation and convenient for maintenance.
Main Features:
This hydraulic core drilling rig, equipped with crawler, has a hydraulic driving system. It owns a compact and advanced structure, with its power head driven by a variable motor and its speed adjustable for 2 gears. With the oil cylinder working with a speed-changeable chain, its performance is stable and reliable. The angle of mast is adjustable from 0° to 90° to ensure a proper hole-drilling angle. The low gravity center of this hydraulic drilling machine promises a steady operation. It also provides operators with a convenient and comfortable working circumstance with a wide view. In short, our HYDX-6A full hydraulic drilling rig has a beautiful outline and shows a people-oriented design idea.
1)Advantages:
(1)Reliable Quality
The main parts and auxiliary equipment, including the engine, diesel engine, hydraulic pump, gear reducer and some key valves and hydraulic accessories, are all products with well-known brands.
(2) High Efficiency
Big torque, powerful driving force, rational and practical design, advanced controlling mode and a 6-meter-long (19.7 feet) drilling rod guarantee the high operation efficiency of this hydraulic core drilling rig.
(3)Environmental Protection
The diesel engine is professionally designed to reduce noise and other contamination (the noise cannot over 72 db), which makes this hydraulic drilling machine proper to be operated in urban areas.
(4)Energy Saving
The advanced technique of loading-sensor-controlling helps to reduce the rig’s consumption of driving force and heat discharge to the minimum.
HYDX-6A full hydraulic drilling rig has an outstanding external appearance, a compacted structure, reliable functions and a flexible operating system. All these elements have made this hydraulic core drilling rig the best choice among the same products in both domestic and abroad markets.
2.Application Range
This hydraulic drilling machine can be applied to both slant and vertical drilling. Being a rig equipped with diamond and the carbide alloy bit drilling, this full hydraulic drilling rig can be used in the fields of geology, metallurgy, coal mining, nuke industry and hydrology measuring.
