Classification and characteristics of domestic anchor drilling RIGS

At present, most of the anchor drilling RIGS in our country are mainly designed for rock anchor work. According to the technical performance of the drilling RIGS, they can be roughly divided into two types:

1. Fully Hydraulic Anchor Drilling Rig

This type of drilling rig has its rotary power, propulsion power and auxiliary actions all driven by hydraulic power. The hydraulic station is driven by an electric motor or an internal combustion engine. This type of drilling rig has a wide adjustment range and is suitable for larger hole diameters and depths. It has good hole-making and anti-stuck drill capabilities, and is flexible and convenient to operate. It is currently the type adopted by most domestic manufacturers.

2 Electric-hydraulic anchor drilling rig

This type of drilling rig is powered by an electric motor for rotation and by hydraulic power for propulsion and auxiliary actions.

The characteristics of foreign anchor drilling RIGS

At present, most of the foreign anchor drilling RIGS used by domestic construction teams are fully hydraulically controlled and powered by internal combustion, equipped with hydraulic rock drills. They have a single power source, a large processing range, and are suitable for both soil anchors and rock anchors. However, they have greater advantages when used for soil anchors.
