Detailed Product Description

1. Application
YG-50 construction drilling rig is a full hydraulic operated top drive power head drill machine. It is applied to drill heavy duty pretension anchor holes at side slope of water power station, railway or highway projects, to drill drainage holes and grouting pile holes on roof of tunnel (gallery). It also used to prevent or solve geologic calamity, such as landslide and rock collapse etc. In addition, it is also used to drill high-pressure jet grouting holes.

2. Features
1) It has great drilling capability, wide range of application , rapid drilling speed and high drilling efficiency, as well as powerful ability of eliminating accident.
2) Extension mechanism in the output spindle of top drive power head can protect drilling tools effectively. It can increase the hole inclination angle range and drill elevation angle holes, while setting the top drive power head and hole top plate toward the opposite direction.
3) A set of front-mounted adjustable columns on drill frame is used for adjusting the height of mast front-end, which makes it convenient to align with hole site.
4) Rig structure is separate group design, it offers good disassembility , rapid and convenient mount and transport, better working environment and lower labor strength as well as remote control and operation.
5) Mast can be fixed on staging immediately without drill frame with auxiliary parts (horizontal axle and buckles), which makes it possible for greatly reducing rig weight and fast moving.
6) The hydraulic motor, pump are world famous brand products, other main assembly are preferentially selected home made reputed products with high quality. All these ensure the rig has stable running 
performance, reliable product quality and long service life. It has good interchangeability due to the high grade of standardization and seriesization of wearing parts.
7) Fully hydraulic drive and operation, stepless shift, simple operation, convenient maintanance and few wearing parts.
8) The rig is suitable for various drilling methods such as carbide bit drilling, auger drilling, DTH hammer drilling, follow-up casing drilling, etc.
