HF-4T tower mounted economic core drilling rig

1.Application Scope

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. The rig  is  simple  in  structure,  reasonable  in  design,  light  in weight, easy to operate; it is in a wide range adjusting angle. It is especially suitable for drilling  of hole with great slope angle.

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°.

2. Main Sizes

 3.Main Components

The drill tower consists of base, tower body, crownblock  (pulley mechanism),  platform and auxiliary support.

4. Main Characteristics

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. 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. The tower can be adjusted in clock-wise direction for drilling  inclined  holes. The adjustment  is convenient  for making  and wide in adjusting  range.  It is suitable for drilling large-angle  hole.
