MD-50 Anchor Engineering Drilling Rig

MD-50 Anchor Engineering Drilling Rig is the National "Eighth-Five" SciTech Tackling Items, that belongs to the portable total.

MD-50 Anchor Engineering Drilling Rig is the National Eighth-Five SciTech Tackling Items, that belongs to the portable total hydraulic dynamic head-type drill rig for anchoring engineering. It is designed by the Prospect Technological Institute of the Ministry of Geology & Minerals and produced by Wuxi Prospect Machinery General Factory of Jiangsu. The products passed the experts appraisal organized by the SciTech Department of the Ministry of Geology & Minerals in April 1995, which the experts regarded that the drill rig possesses the innovation design with its performance and outline designing keeps ahead among the same lines in China.

    During 1996, the products were awarded the title of New Products in State Level by National Committee of Economy & Trade.

    MD-50 Anchor Engineering Drilling Rig is mainly for the anchoring engineering of coast and dangerous rock/cliff mass for geological disaster prevention activity, and the anchoring engineering of high-edge slope or dangerous rock body etc to control displacement of buildings, and also for supporting of deep-foundation pit and groundwork reinforcing engineering in urban construction site, for blowing up engineering or blowing up hole etc.

    Alternating of the drilling rig can also be applied for high-pressure revolving-spraying pole for construction engineering, for the support hole of tunnel tube shed, or for convenient constructing of facing upward hole after alternating of its installing position for sliding frame.

    MD-50 Anchor Engineering Drill Rig possesses the characteristics of stable performance, high working efficiency, multiply usage, as well as the capability of drilling sophisticated stratum and handling accidents etc. This drilling rig, deployed by common alloy drill tools or other drill tools, can perform revolving-and-drilling. In the rigid rock stratum, the drilling rig deploys the spheroid drill bit to perform striking and revolving and drilling to have high-speed-bored hole; if deployed with air-compressor and pneumatic in-the-hole hammer, and accepted the casing-followed drill tools, the drilling rig can drill the hole with casing together in those unstable stratum such as conglomerate stratum.

The drill rig has the following features:

1) simple structure, light weight, strong disorganization, easy moving and installing, strong applicability to construction site, more suitable for constructing on the falsework.

2) equipped by special cannula-followed drill tools (such as drill rod, casing, eccentric bits etc), using the casing-wall protecting-boring technology in unstable stratum and deploying the spheroid drill bit to finish the boring. High boring efficiency and satisfying bring quality.

3)  This drilling rig has a wide scope of drill angle from elevation 10°to depression 90°or alternated to elevation 90°to depression 10°, the slide frame can sliding and moving to-andfro along with bottom frame with easy and reliable boring and orientation. The drill rig is lower in the central so that moving of drill tolls up-and-down is very convenient.

4)Total hydraulic control with easy operating, saving time and energy.

5)  With orifice dust-collecting device to reduce environment pollution and to improve working environment
