Mining Drilling Jumbo

CYTJ45 Single-Boom Mining Drilling Jumbo

The CYTJ45 is a single-boom mining drilling jumbo for medium and large underground drifts and tunnels, integrating face blasting-hole drilling and rock-bolt hole drilling on one platform. It is offered in two configurations: a hydraulic baseline and an intelligent low-profile variant. CYTJ45(A) is the hydraulic baseline, with a Yuchai 81 kW CN IV diesel, a 22 kW-class hydraulic rock drill and a five-option feed range from 3.4 m to 4.6 m. CYTJ45(Z) is the intelligent variant, custom-sized for low-height tunnels on a smaller 55.8 kW CN stage IV diesel, equipped as standard with a fully computerised control system, a blast-hole layout design and import workflow, an on-board scanner module for face point-cloud capture, and automatic adaptive drilling. Both variants share a FOPS/ROPS cab with air conditioning, automatic shank lubrication and a 22 kW rock-drill impact-power class. CRCHI Australia handles commissioning, parts and aftermarket support nationally. For larger civil-tunnel cross-sections, the ZYS-series tunnel drilling jumbos in our tunnel excavation and support range scale the same drill-and-blast approach to two, three and four booms on a cable-tethered electric chassis. ZYS has no 1-boom variant, so the CYTJ45 single-boom remains the narrow-drift configuration in the CRCHI line.

Overview

Applications

Face advance and rock-bolt hole drilling in underground mine drifts, declines and drives, with the same platform suited to water-conservancy adits, hydropower headrace tunnels and underground civil works in medium and large cross-sections. CYTJ45(A) covers a maximum working face of 8.4 m by 7.6 m and a minimum face of 3.7 m by 3.5 m on a 16 t platform; CYTJ45(Z) covers 7.9 m by 7 m down to 3 m by 3 m on a 13 t platform sized for low-height tunnels.

Performance

Total power 68.5 kW on both variants. Rock drill impact power 22 kW. Drilling diameter 45 to 89 mm. Drilling speed up to 3 m/min. Maximum drilling depth per rod 3.4 m, 4.0 m or 4.6 m on (A) across the five feed options; 3.4 m standard on (Z) with 4.0 m available on the optional 14 ft feed. Maximum climbing capacity 25%. Maximum travel speed 17 km/h on (A) and 13 km/h on (Z). Altitude rating 2000 / 4500 / 5300 m on both variants. (A) total weight 16 t with overall length 12.4 to 13.1 m by feed; (Z) total weight 13 t with overall length 11.3 to 11.5 m.

Functions

Single-boom hydraulic drilling jumbo combining face blasting-hole drilling and rock-bolt hole drilling on one platform. Hydraulic boom levelling for parallel hole positioning. Hydraulic rock drill with anti-jamming and anti-idle-strike control and automatic retraction. Articulated 4WD chassis with hydrodynamic transmission and wet axle drive. Multi-degree-of-freedom boom for peripheral holes and bolt holes at varied angles. FOPS/ROPS cab. Electrical system with insulation monitoring, phase-sequence detection, leakage protection and motor-fault indication. Informationisation gateway streaming drilling-depth, propulsion-speed and impact-pressure log data, plus on-board video, to a mining information system. On (Z), a fully computerised control system adds digital tunnelling design import, parking guidance, rapid machine positioning, scanner-based face capture, automatic adaptive drilling and operation-log generation.

Benefits

One platform covers face drilling and rock-bolt drilling without a machine change. Hydraulic boom levelling and electronically controlled fine positioning shorten the time to set up each round. Anti-jamming and anti-idle-strike protection extend rock-drill life and reduce in-cycle interruptions. The FOPS/ROPS air-conditioned cab improves operator comfort across long shifts. Choosing (Z) over (A) shifts the workflow from operator-marked drilling to scanner-captured face geometry, blast-hole-plan import and automatic drilling, with optional remote control reducing personnel exposure at the face. Both variants share components with the wider CRCHI mining range for parts commonality and serviceability, supported in Australia by CRCHI Australia.
