Zfy Raise Boring Machine for Shaft Reaming From Dia. 3.5m

1,Performance parameters of raise rig2. Main purpose of raise rig:

The raise rig is an efficient equipment for drilling underground wells (ore bin, ventilation hole, water and electricity system pressure pipe, cable equipment well, etc.). The products have been widely used in coal mines, metal mines, water conservancy and hydropower projects and other fields, and are well received by users, and have achieved good economic and social benefits.

3. Scope of application:

The raise drilling rig is applicable to all kinds of hard rock f3-f12. For the super hard rock f12 (compressive strength 1200kg/cm2), a special reamer can be customized to meet the requirements of broken rock.
The lift rig has the potential of large capacity and high safety factor, and can be applied to well construction projects with different diameters and depths and 600-900 degrees of inclination.

4. Environmental conditions for use:

The raise drilling rig is a construction equipment for drilling the shaft between two working levels: the upper level and the lower level for short. The working site for drilling rig construction is at the upper level, which can be roadway or chamber, or open air, which is called the working point. The penetration point for drilling rig construction is at the lower level, which is generally roadway or chamber, which is called the penetration point.
The drilling rig is explosion-proof and applicable to various working places with explosion-proof requirements (such as gas mines at all levels).

5. Security:

The raw materials, standard parts and purchased parts used by the raise rig comply with relevant national standards and industrial standards, and the purchased parts have certificates of conformity.
All electrical equipment used by the raise rig shall comply with the provisions of GB3836.1 and GB3836.4, and shall be attached with the certificate of conformity.
