Advantages:
1, Automatically loading and unloading drill pipe, labor saving, more safety.
2, already fitted with air compressor.
3, the arm is aluminum alloy, more durable.
The large-section aluminum alloy guide rail ensures sufficient strength, and it is
equipped with a flexible and
convenient automatic loading and unloading drill pipe mechanism and drill pipe magazine
to improve work efficiency and
reduce work intensity.
The capacity of the drill pipe storage is 7+1, and the depth of the drill pipe is 24m.
The highly centralized control
console is simple and convenient in layout, and it is more intuitive and clear to judge
the status of the drilling rig.
All action instructions are clear and easy to operate.
Equipped with a dry-type high-efficiency dust collection system to provide a comfortable
working environment.
The engineering crawler is equipped with a frame leveling oil cylinder, which has strong
climbing ability and is
suitable for all kinds of rough roads.
