June 25,2026
With the official formation of LiuGong's underground equipment product line, LiuGong wheel loaders, backed by 60 years of robust intelligent manufacturing strength, provide users with a solid guarantee in five core areas of full-domain safety, hard-core durability and reliability, comfortable driving and operation, and convenient maintenance, saving worries for users!
Today, we will introduce in detail the LiuGong CYTJ45 mining hydraulic jumbo drill, with a stronger drilling arm and more stable hydraulic control, making tunnel excavation fast, stable, and accurate!
Pioneer in Tunneling
CYTJ45 Mining Hydraulic Jumbo Drill
Hard Rock Conqueror High-performance Configuration Efficient Rock Drilling
✅Efficient Drilling Without Bit Jamming: Equipped with internationally and domestically renowned high-power rock drills, reliable in quality, with high impact power, fast drilling speed, and low maintenance costs, meeting different rock grades.
Equipped with Automatic Anti-Jamming, featuring automatic stop impact, automatic retraction, and other functions, effectively reducing bit wear and extending the life of drilling tools.
✅Hard-core Hydraulics, Energy-efficient and High-performance: The core hydraulic components are selected from the Rexroth brand, stable and reliable, providing strong assurance for high-intensity continuous operations. Using load-sensitive static hydraulic systems, it is responsive, flexible to operate, energy-efficient, and high-performance.
✅Narrow Laneway Navigation, Flexible Transition: The overall machine height is lower, with a larger departure angle, offering better passability. The vehicle speed is 11km/h, with faster travel speed and higher transition efficiency.
Intelligent Drilling Solving Over-excavation and Under-excavation Issues
✅More Flexible Positioning: 8 degrees of freedom working arm, dual-triangle hydraulic automatic leveling drilling arm, rock drilling without blind spots, one-time positioning for rapid drilling, avoiding frequent adjustments of the rock drill, easy to learn, directly improving drilling efficiency.
✅More Accurate Drilling: Core construction data is fully digitized, with pressure, flow, hole depth, and other key parameters clearly visible, accurately controlling the drilling effect, solving over-excavation and under-excavation issues, ensuring tunnel shape quality, and meeting stringent construction requirements.
Safety First Multiple Protections Ensuring Operational Safety
Dual-circuit full hydraulic wet driving brake, SAHR hydraulic parking brake, parking brake override function, high ground clearance design, safe and reliable travel.
The design of electrical key components is protected at IP65 level and above, equipped with FOPS and ROPS double-certified enclosed cab, ensuring safety, effectively reducing noise during construction, and escorting long-term non-fatigue operations. Electronic fencing can be added for all-round protection of underground personnel.
Reliable and Worry-free Convenient Maintenance Worry-free Operation
Equipped with electronic intelligent monitoring and diagnostic system integrated large screen digital instrument, it can achieve full intelligent and remote control functions, real-time monitoring of the entire machine status, fault detection, and information display in one screen, reducing downtime due to faults, and making equipment management easier.
Rotatable cable drum, air compressor design, and peripheral arrangement design of the entire machine filter, making maintenance more convenient, without delaying the construction period.
