HF-4T core drilling machine with competitive price

Application Scope:

1.The HF-4T core drill rig, integrated rig with tower into one unit, consists of HF-4 drill rig and mast-type drill tower, with the function of hydraulic lifting and lowering of tower.

2.The rig is simple in structure, reasonable in design, light in weight, easy to operate; it is in a wide range adjusting angle.

3.It is especially suitable for drilling of hole with great slope angle.

4.The tower body of HF-4T Drill Rig is used as lifting drill tools for drilling vertical as well as inclined holes. The range of adjusting angels (in clock-wise direction) for drilling inclined holes is 0°-90°.

Main Characteristics:

1.The drill tower is pyramid-mast type. Being light in overall weight, single component being light and limited in disassembly quantity, the tower is convenient for transportation and installation.

2.The tower has its own crownblock convenient for ground installation. When the rig is moved back during operation, the tower can be inclined to make up the moved-back distance so as to guarantee the central line between the centers of the hole and pulley.

3.The tower can be adjusted in clock-wise direction for drilling inclined holes.

4.The adjustment is convenient for making and wide in adjusting range. It is suitable for drilling large-angle hole.
