Adopt the hydraulic retractable track chassis special for the rotary drilling
rig, which meets the stability and the convenience of the transportation.
-
Adopt imported Cummins engine with strong power and enough power reserve, which
can meet the highland construction. The noise and emission meet the standard of
Europe III.
- The patent parallelogram variable structure realizes the
large-scope working area. The whole variable system is made of high-intensity
materials, which has strong stability, ensures the mast moving stably, and makes
the drilling tool position accurately and not affect the verticality. All the
articulated joints of the variable system adopt the lubrication-free bearing
which can rotate freely.
- The hydraulic system adopts the load sensing
technology, which improves the efficiency of the hydraulic system and saves the
energy.
- It can be installed with many kinds of drilling tools, realizing
both dry and wet drilling work which can be applied to the concrete pile
drilling construction of many kinds of foundations. The drill rod adopts lock or
friction drag retractable structure, and transmits torque to the drilling tools
through the claw or friction plate, which has big transmission torque and high
efficiency.
- The main winch steel wire rope adopts single winding, which is
convenient to operate, and greatly improves the service life of the steel wire
rope. There is drilling depth detection device installed on the main winch. The
single winding makes the depth detection more accurate, and is convenient to
maintain.
- The drill unit adopts the imported reducer and motor of
international famous company, which have big drilling torque and high work
efficiency.
- Install the infrared camera to observe the service condition
of the main hoist in the cab day and night
