JCDRILL Crawler DTH Drilling Rig with Diesel Hydraulic System for Surface Blasting and Borehole Construction

>> Products Description

Engineered for tough rock formations and highefficiency down-the-hole drilling, JC617 combines robust structural design with advanced hydraulic control to deliver exceptional drilling performance in challenging conditions. With its ability to handle rock hardness levels up to F=20 and drill diameters ranging from φ90 to 100mm, JC617 is especially suited for surface mining, quarry operations, and infrastructure foundation work. The rig adopts a reinforced feed and rotation system that ensures powerful penetration capacity. It delivers a maximum rotary torque of 2400N·m and operates at a rotary speed suitable for deep, precise drilling. The drill string features φ64mm × 3000mm rods, optimized for both strength and adaptability in fragmented or abrasive formations. Powered by a high-output diesel engine, JC617 is equipped with an efficient hydraulic system that controls feeding, lifting, rotation, and positioning functions through a centralized interface, enabling smooth operation and reduced manual effort. The integrated design enhances  operational safety while improving energy efficiency across long drilling cycles. The heavy-duty chassis and stable tramming structure allow the rig to maintain reliable mobility across complex terrain. Dust suppression, sealed electrical components, and a user-focused maintenance layout minimize downtime and enhance the machine's durability in harsh outdoor environments. Whether used in mineral exploration or production drilling, JC617 delivers consistent results with lower operating cost and longer service life.

>> Application

Surface Mining Operations
JC617 is designed for precision and strength in surface mine drilling. With a rated torque of 2400 N·m and the ability to drill up to 30 meters deep, it handles hard rock formations (up to F=20) with ease.

Quarry Drilling and Stone Extraction
Perfect for granite and basalt quarries, the JC617 delivers consistent performance in abrasive and fractured rock conditions, supported by φ64 mm drill rods and 3"/4" hammer compatibility.

Mid-Scale Exploration Projects
The energy-efficient Yuchai engine and dual-motor rotation system make JC617 suitable for mineral prospecting and medium-depth core drilling where power and maneuverability are equally critical.

>> FAQ

Q1: What is JC617 best used for?
A1: JC617 is ideal for surface mining, quarry drilling, and infrastructure foundation projects that require precision and power in medium-to-hard rock conditions.

Q2: What drilling depth and hole diameter does JC617 support?
A2: It can drill up to 30 meters deep with a hole diameter range of φ90–100 mm, using 3" or 4" DTH hammers.

Q3: What kind of engine powers JC617?
A3: It is powered by a 78 kW Yuchai diesel engine (Model YCD4T22T-105A), offering reliable output and low fuel consumption.

Q4: Can JC617 handle difficult terrain?
A4: Yes. With a tramming speed of up to 2 km/h, 450 mm ground clearance, and 25° climbing capacity, it is highly capable in rough and sloped conditions.

Q5: What is the air requirement for this rig?
A5: JC617 operates efficiently with an air supply of 9–15 m³/min at a working pressure of 0.8–1.6 MPa, suitable for most medium-hard rock applications.

Q6: What makes the rotation and feed system special?
A6: The rig features a dual-motor rotation system that delivers up to 2400 N·m torque and 150 rpm speed. Its oil cylinder feed mechanism provides a smooth 3340 mm stroke and 15 kN thrust.

Q7: Is it easy to operate and maintain?
A7: Yes. The integrated rear control panel is user-friendly, and the centralized hydraulic system reduces manual effort. The rugged design also minimizes maintenance requirements in harsh environments.

Q8: Does it support automatic rod handling?
A8: While JC617 includes rod handling capability via its feed and lifting system (25 kN lifting force), full automatic rod handling is not integrated by default. Optional winch systems are available for upgrade.
