Changsha Miracleland Import & Export Co., Ltd |
XR320D Rotary Drilling Rig:
Features:
- 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.
