RCF450C 450m Steel Crawler Mounted Water Well Drilling Rig Air DTH
Drilling Machine
Machine Introduction
RCF450C deep water well drilling rig is our independent research and
development products. These new generation DTH are coupled to
higher air power, and thus play a significant role in leading to
faster drilling rates.
Adopting newest model & advanced hydro technology, low consumption, large rotary torque, convenient hole deflection,our water well drilling machine are mainly used for well drilling
in resource exploration and hydrology wells, civil use water well,
agriculture irrigation etc projects.
Made from high quality materials, with fashion and compact design,
that keeps our drilling rigs more efficiency and with low failure
rate, more economic and durable, and with a high comprehensive cost
performance. Our water drilling rigs have received the real market
validation as the majority of our customers’ positive feedback.

Advantage and features
Easy and flexible full hydraulic control
The rig's speed, torque, thrust axial pressure, reverse axial
pressure, thrust speed, and lifting speed can be adjusted at any
time to meet the requirements of different drilling tool working
conditions and different construction processes
Top-drive slewing propulsion lift
It is easy to connect and disconnect the drill pipe, shorten the
auxiliary time, and also facilitate drilling with the pipe.
Multifunctional drilling
Various drilling processes can be used on this rig, such as:
down-the-hole drilling, through-air reverse circulation drilling,
gas lift reverse circulation drilling, cutting drilling, roller
drilling, tube drilling, and Core drilling under development and
more. The drilling rig can be equipped with mud pumps, foam pumps
and generators according to user needs. The rig is also equipped
with various hoists as standard.
High efficiency
Due to the full hydraulic and top-drive slewing propulsion lifting,
it is suitable for various drilling processes and various drilling
tools, with convenient and flexible control, fast drilling speed
and short auxiliary time, so the operation efficiency is high.
low cost
DTH drilling is mainly based on DTH drilling technology. DTH rock
drilling has high efficiency and lower cost per meter.
High outrigger and Tracked walking
The high outriggers are convenient for loading and transportation,
and can be loaded directly without crane. Tracked walking is more
suitable for muddy field movement.
Positive and negative axial pressure adjustment
The optimal impact efficiency of each impactor has its matching
optimal shaft pressure and speed. During the drilling process, as
the number of drill pipes increases, the axial pressure on the
impactor also increases. Therefore, the positive and negative axial
pressure valves are adjusted during construction to ensure that the
impactor can obtain a more suitable axial pressure. At this time,
the impact efficiency is higher.
Rig chassis
It can be a tracked self-propelled chassis or a vehicle-mounted
self-propelled chassis.
High configuration
The main components and hydraulic system are all famous brands. In
addition, the main frame of the rig is made of high-quality
high-strength low-carbon alloy steel, which increases the overall
strength and is very resistant to wear.
