HYDX-6

I. General Introduction

This HYDX-6 hydraulic drilling rig is a new product made by Lianyungang Huanghai Machinery. It is a thoroughly new-typed drilling rig developed on the basis of the advanced techniques in the world. HYDX-6 is reasonable in design, excellent in performance, easy for operation and convenient for maintenance.
HYDX-6 hydraulic diamond core rig can be applied to both slant and vertical drilling. Being a rig equipped with diamond and the carbide alloy bit drilling, it can be used in the fields of geology, metallurgy, coal mining, nuke industry and hydrology measuring. It is an outstanding China drill rig for BQ, NQ, HQ, and PQ drilling.

1. Main Features of the rig:

The hydraulic diamond core rig, equipped with tracks, has a hydraulic driving system. It owns a brief but 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 mast is adjustable in the range from 0° to 90° to ensure a proper hole-drilling angle. The low gravity center of the rig promises a steady operation. And this hydraulic diamond core rig provides the operators with a convenient and comfortable working circumstance with a wide view. In short, the hydraulic diamond core rig has a beautiful outline and shows a people-oriented design idea.
(1) Reliable Quality Hydraulic Diamond Core Rig
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 the rig.
(3) Environmental Protection
The diesel engine is professionally designed to reduce noise and other contamination (The noise can not be over 72db), which makes the rig proper to be operated in urban areas.
(4) Energy Saving Hydraulic Diamond Core Rig
The advanced technique of loading-sensor-controlling helps the hydraulic diamond core rig reduce its consumption of driving force and heat discharge to the minimum extent.
HYDX-6 has an outstanding external appearance, a compacted structure, a reliable function, and a flexible operating system. All these factors have made the rig the best choice among the same products in both domestic and abroad markets.
