Overview of Jumbo Drills
Jumbo drills are essential machines used in underground mining and tunneling for tasks such as blast holes, cross cut drilling, bolting, and grouting. They are designed to withstand harsh conditions and are available in models suitable for both horizontal and vertical drilling. These drills are crucial for mining minerals like nickel, copper, and gold.
Key Subsystems- Carriers: Designed for maneuverability in tight spaces with articulated designs.
- Booms: The MD and UTB series feature robust hydraulic cylinders and semi-automated systems for precise positioning.
- Drills: The HPR series rock drills are high-performance with fewer parts, reducing maintenance costs.
- Drill Feed: The TR Series Aluminum feed is customizable and easy to maintain, significantly reducing downtime.
Advanced Features- Smart Cables and Hoses: Simplify maintenance and inventory management.
- 78-piece Rock Drill: Simplified design for easier maintenance and reduced costs.
- Accumulator: Easy to exchange and maintain with long intervals between reseals.
- Anti-jam and Constant Sting Features: Enhance operational efficiency and reduce downtime.
Specific Models- MD2025: Small one-boom jumbo for narrow seams, available in diesel and electric power.
- MD2040: Single-boom jumbo with an efficient hydraulic system for various applications.
- MD2060: Two-boom electric/hydraulic jumbo known for reliability and flexibility.
- MD2070: Large two-boom jumbo with advanced automation for complex tasks.
Shaft Jumbos
Shaft jumbos are designed for vertical development in mining, available in configurations with 1 to 4 booms and options for electric/hydraulic or pneumatic versions. The choice of configuration depends on factors like the permissible weight of the galloway or head frame.
Shaft Jumbo Specifications
Each shaft jumbo is customized to meet specific requirements, with configurations influenced by the size of the bucket well and maximum winch load. The carrier design accommodates all control systems and enhances face coverage by nearly 25% with features like knuckles and boom extensions.
Power Units
Shaft jumbos can be equipped with electric or pneumatic power units. The electric unit is lighter, while the pneumatic unit is suitable where mine electricians are scarce. Control options include proportional electric controls or manual hydraulic valve controls.
Drill Options
The HPR3818 drill is available for blast holes, while the HPRH45 is suitable for both blast holes and reaming.
Features and Benefits- General: The jumbo frame supports control systems for a customized fit, with boom extensions and parallelism increasing face coverage by 25%.
- Rock Drill: Hydraulic drifter offers high-performance drilling with low operating costs and easy maintenance.
- Boom: Designed for 270° rollover and 360° boom roll for enhanced flexibility.
- Feed: Features replaceable stainless steel wear strips and innovative retainer clips for quick installation, reducing maintenance time by 75%.
Pneumatic and Electric Power Unit Configurations
Configurations vary by the number of booms, boom length, extension, feed, control type, and drill model. Options include manual, electric, or radio remote control with drills like HPRH4519 or HPR3818.
