I. General Introduction
YDX-3000 Hydraulic Core Drilling Rig, an up-to-date multifunctional
product made by us, is a thoroughly new-type hydraulic core
drilling rig developed on the basis of the market demand and the
advanced techniques in the world. It is suitable to use in plains,
hills, high temperature as well as low temperature places. The main
machine is integrated in structure, which consists of
self-propelled chassis, power, mud pump and hoist, etc. It is
wire-line coring, and at the same time has the unique top drive
function. The maximum torque is 23500N.m(17320 lbf.ft), which will
be much more suitable for large dia. drilling in coal bed methane,
hydrology and water well. According to many years of experience in
HDD field, our engineers install clamp and shackle device on the
rig to relieve labour intensity, improve drilling efficiency and
guarantee operator's safety.. YDX-3000 is excellent in performance,
high in working efficiency, easy for operation and keep the
operators from dangers. II. Specifications 1.
