Introduction

HFMG-170 crawler type anchor drilling rig is the high efficient drilling rig machine that developed based on the domestic subway, high-rise buildings, airports, and other deep foundation pit anchorage, rotary spraying and dewatering. It can achieve the construction of foundation pit dewatering and micro piles filling through configuring different modules. It is equipped with crawler chassis, high rotary platform, oil cylinder with large diameter support leg, 0.9 meters sliding frame and orifice support device, making the rig movement, positioning very convenient, stable and reliable when drilling.

Features

* Automatic stop impacting at the end point, automatic anti-jamming, and automatic induction of water and slag discharge.

* Crawler type walking mode, stable working performance, good climbing ability.

* Compact structure, low centre of gravity, flexible movement.

* It can not only drill the blasting hole, but drill the anchor hole after installing the propeller.

* Singe power source of whole machine, low energy consumption and low noise, improving working conditions substantially and increasing the construction efficiency and quality, special suitable for narrow channel operation.

Application

Hydraulic crawler type anchor drill rig is mainly used for anchor cable reinforcement of power plants, roads and the rail mountain slope, advance support of pipe shed, anchor cable of foundation pit pile, anti-floating anchor rod, subgrade strengthening, hydropower project dam foundation and dam body seepage control treatment, mine and quarry blasting hole, miniature pile hole, etc. It is especially suitable for deep hole and pipe drilling in boulder, grait, gravel and broken strong weathered rock covered stratum.
