Product Overview

The Huatai CYTJ45/2 is a dual boom hydraulic drilling jumbo (双臂液压掘进钻车) purpose-built for efficient tunneling and development drilling in underground mining operations. Equipped with two independently controlled hydraulic telescopic booms, this rig enables simultaneous multi-face drilling, dramatically reducing blast cycle time and improving overall tunneling productivity.

Designed for medium to large cross-section tunnels, the CYTJ45/2 covers excavation profiles from 2.5m × 2.5m up to 5.5m × 5.5m. Its electric-hydraulic drive system delivers consistent power output with zero underground emissions, while the heavy-duty crawler chassis provides stable mobility on rough and inclined mine floors.

Technical Specifications

Key Features & Advantages

• Dual Boom Simultaneous Drilling: Two independently controlled hydraulic telescopic booms allow parallel drilling on the tunnel face, effectively doubling drilling speed compared to single boom rigs. Each boom covers its designated section without interference.
• Wide Cross Section Adaptability: Engineered to handle tunnel profiles from 2.5m × 2.5m (development headings) up to 5.5m × 5.5m (large production tunnels), making it a versatile investment for mines with varying excavation needs.
• Electric-Hydraulic Drive System: 45kW electric motor powers the hydraulic circuit, delivering consistent high-pressure output with zero underground exhaust emissions — ideal for confined mine environments requiring ventilation compliance.
• Heavy-Duty Crawler Chassis: Steel track undercarriage with 30° climbing capability and 2km/h travel speed ensures stable repositioning between blast cycles on rough, inclined underground terrain.
• High-Precision Drilling Control: Advanced hydraulic control valves and anti-jamming automation ensure accurate hole positioning and consistent drilling depth, reducing overbreak and improving blasting efficiency.
• Operator Safety & Comfort: Enclosed operator cabin with FOPS/ROPS protection, ergonomic joystick controls, and excellent visibility of both booms for safe and precise operation during extended shifts.
• Low Total Cost of Ownership: Efficient hydraulic system design combined with durable wear components minimizes energy consumption and maintenance downtime. Common spare parts are readily available worldwide.

Recommended Applications

• Underground metal mine development drifting and production drilling
• Coal mine main roadway and cross-cut excavation
• Hydropower station diversion tunnel construction
• Railway and highway tunnel face drilling
• Large underground cavern excavation (crushing stations, workshops)
