Ⅰ. Application Scope
The HXY-4T core drill rig, integrated rig with tower into one unit,
consists of XY-4 drill rig and mast-type drill tower, with the
function of hydraulic lifting and lowering of tower. The
geotechnical drilling 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 HXY-4T vertical spindle core drilling 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°.
Ⅱ. Main Sizes
The Nominal Height of Tower | 10 m (32.8 feet) |
The Nominal Area of Base | 4×4 m (13.1×13.1 feet) |
The Number of Pulleys | 3 or 5 pcs |
Max. Load of Mast | 100 KN(22480 lbf) |
The Load of Movable Work Platform | 80Kg (176.4 lb) |
Adjusted Angles of Drill Tower | 45°-90° |
Ⅲ. Main Components
The drill tower consists of base, tower body, crownblock (pulley
mechanism), platform and auxiliary support.
Ⅳ. 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.
