island, mountain, tropical rain forests, as well as the area which
does not permit of excavation such as crowded buildings, cultural
relic preserve zone, pipeline located region. Key features:
PLC Control systemPLC control system, High response speed and
Smooth operationMain pump for rotary and pull back is Electric
proportional plunger pump which is high efficiency, High bearing
pressure capability and Long life.Dual speed for rotary,pull back
and track moving, controlled by electric proportional control
system and continuously variable transmission.All-in-one
multifunctional controller, rotary,thrust/pull back as well as
other main action. It supplies simple, convenient and comfortable
efficient operation.Four-bar swing arm linkage structure provides
steep entry angles without raising the tracks off the ground;
ensure the stability of drill rig in operation.Wrench skewed 10
degrees inward, towards the operator, easy to observe wrench
action.Wrench with buffer spring avoids damage the thread of
drilling rod and wrench by human error.Rack-and-pinion thrust
structure, the rotary head is driven by double pullback motors and
reducers.Steel track with rubber blanket provides high strength and
long life;Wire control system for dual speed track moving, safe and
reliable. DDW-3512 SPECIFICATIONMAIN
