In addition, the whole machine adopts a modular disassembly design
with a clear layout of core components, enabling convenient
disassembly and assembly. Daily inspection, maintenance and parts
replacement procedures are simple without the need for professional
complex tools, which greatly reduces the difficulty and cost of
later operation and maintenance, prolongs the service life of the
equipment and delivers high comprehensive cost performance.
Widely applicable to blasting hole drilling operations for various
open-air projects, the R55 dth drilling rig is mainly used in
quarrying, open-pit mining, highway and railway road construction,
water conservancy and hydropower projects, power infrastructure
construction, national defense infrastructure projects, municipal
earthwork and other large-scale open-air construction scenarios.
With high drilling accuracy and strong geological adaptability, it
can meet the drilling requirements of different apertures and
geological conditions, serving as a core key equipment for open-air
blasting construction.
1. Adopts 4‑wheel and 1‑belt system for construction machinery,
with reliable performance and low failure rate.
Adopts plunger type traveling motor, with strong climbing capacity
and stable rig movement.
The control pedal can effectively improve the operator's safety
during rig relocation.
2. The multi‑way valve is reasonably arranged, bringing convenient
and quick maintenance and pressure adjustment.
The LCD display can accurately monitor the operation status of the
three‑stage diesel engine, automatically switch operation modes
according to actual working conditions, and has self‑diagnosis and
alarm functions.
3. Yuchai three‑stage diesel engine, with strong power, reliable
and stable operation.
4. 12‑filter element dust collector, with reasonable installation
layout, strong negative pressure and good dust removal effect.
Rear‑mounted radiator, and the diesel engine adopts suction fan,
bringing excellent cooling effect for the whole machine.
5. The rotary head is driven by dual hydraulic motors, with compact
structure, convenient maintenance and large torque.
The sliding block is made of polymer wear‑resistant material, with
strong resistance, convenient maintenance and stable operation.
6. 120L diesel tank ensures 8 hours of continuous drilling,
reducing auxiliary operation time.
7. The traveling acceleration switching valve enables two traveling
speeds of the drill rig, bringing convenient and quick relocation
and site transfer.
8. The large‑bore leveling cylinder improves the structural
strength of the whole machine, with stable and reliable vehicle
body floating.
