Core Drilling Rig, HF-44A
Application
The HF-44A core drilling rig is designed with a diamond drill bit and alloy drill bit. Used for engineering geological exploration, natural gas mining, mine tunnel ventilation, drainage, water well drilling and large diameter foundation pile construction, the land drilling rig is safe, efficient, and reliable with computer control.
Japanese customer testing HF-44 intelligent drilling rigMain Features
1. Due to a digital electrical control system, the HF-44A oil rig can set the torque limit value according to the torsional strength of the drill pipe being processed, making it safe and reliable for loads that are too large or suddenly increased.
2. The mining drilling equipment’s rotary is driven by a DC speed regulating motor that realizes stepless speed changes. HF-44A automatically regulates the rotary speed according to the rig’s working conditions.
3. Our core drilling rig's drill winch is driven by an AC frequency conversion motor and control system, which is efficient in hoisting and stepless speed as well as helps to minimizes the chance of accidents during operation.
