Trajectaflex Resin Firing System
The Trajectaflex Resin Firing System is an innovative single-pass solution for resin capsule installation in resin-set bolting. Designed for use with most development jumbo drills, the system enables simultaneous drilling of bolt holes and insertion of resin and bolts.
Using a volume of air pressure, the Trajectaflex system propels resin capsules through a flexible nozzle assembly directly into pre-drilled bolt holes. This nozzle assembly is securely mounted at the end of the jumbo feed rail on an independent slide, offering the convenience of extension and retraction beyond the jumbo boom, ensuring precise bolt hole alignment.
The Trajectaflex nozzle assembly, as illustrated, comprises six easily replaceable parts, providing a user-friendly and efficient solution for your resin bolting needs.

Resin capsules are easily loaded into a manifold, located on or alongside the operator’s platform. With the release of air pressure, they travel along the jumbo boom through a connecting delivery line, passing through the Trajectaflex nozzle, and into the pre-drilled hole.
Inserting Trajectaflex nozzle into the pre-drilled bolt hole is easy. When the nozzle tip engages with the bolt hole collar, a small boom movement, combined with the Trajectaflex spring flex, allows for perfect alignment of the nozzle tip with the bolt hole, as depicted in the image.
NOTE: Resin capsules can be fired through the Trajectaflex nozzle while maintaining spring flexibility, eliminating the need for precise nozzle alignment.
Key points
Adaptability and ease of use
- The Trajectaflex Resin Firing System seamlessly adapts to any Jumbo drill.
- It can be quickly and easily removed when not in use, allowing the Jumbo to switch to face drilling without limiting its drilling capabilities.
Design and functionality
- To maintain resin capsule integrity the Trajectaflex system has been engineered for a smooth transition, all components facilitate the unimpeded passage of resin capsules, reducing the risk of ruptures during the firing process.
- A precise alignment between the nozzle tip and the bolt hole is vital to prevent ruptures as resin capsules exit the nozzle and contact the bolt hole sidewall.
- The long, flexible nozzle tip of the Trajectaflex ensures consistent, perfect alignment, pushing past fractured rock to secure proper placement and minimise resin capsule damage.
Innovative nozzle design
- The patented nozzle, developed by an experienced jumbo operator, prioritizes simplicity and low maintenance while maintaining the integrity of resin capsules from loading to lodging in the bolt hole.
- Ensuring the proper placement of resin capsules within the bolt hole maximizes bolt strength, integrity, longevity and reduces bolting cycle times.
- Robust system allows operators to install resin capsules in a timely and seamless manner.
- Trajectaflex system allows Jumbo boom movement flow to be at its optimum.
Product advantages
Safety
- Adheres to best practices by installing ground support while advancing.
- Reducing labour needs and minimizing the requirement for physical alignment checks and resin capsule reloading.
- Loading resin capsules directly from the platform reduces the need for repeated machine mounting, decreasing operator fatigue and potential injuries.
Simple design
- The innovative spring mechanism enables easy bolt hole location through nozzle flex and self-indexing.
- Robust design allows for probing the hole without damaging the nozzle, with minimal adjustments needed for alignment.
- Quick and easy nozzle removal and disassembly, with most parts removable by hand, ensures minimal downtime and compatibility with various feed rail profiles and machines.
Efficiency
- Streamlined bolting cycle times are achievable, facilitating single-person operation.
- The system’s intuitive design enhances user experience and maintenance ease. A low maintenance system with minimal work required during drill servicing.
- Reduced tool changes are required, as drilling, resin loading, and bolt installation occur in a single pass, keeping the drill operator on the work platform for extended periods and enhancing productivity and safety.
Auger Drill Steel
Auger Drill Steel: Game-changer in mine drilling
A self-cleaning full length reverse spiral drill steel designed to excel in challenging, collapsing ground conditions. This revolutionary tool not only enhances resin bolting but also redefines other mine drilling applications requiring clear boreholes.
The Auger Drill Steel is poised to revolutionize resin bolting and other mine drilling tasks, in challenging ground conditions. Wilco Technologies extensive experience in the underground hard rock mining industry supports the efficacy and necessity of this innovation.
Quality assurance and manufacturing excellence
In the preliminary stages of importing Auger Drill Steels for trial work, we have prioritized quality and reliability. Our manufacturer, a specialist in drill steels and consumables since 1996, exceeds ISO 9000 standards through an externally audited quality assurance program. The commitment to a rigorous multi-point inspection ensures the highest standards are met.
Personal experience and endorsement
“After witnessing the Auger Drill Steel’s benefits during a mine site visit overseas, I am convinced of its transformative potential for mining in difficult ground conditions. The Auger Drill Steel promises significant returns in productivity, quality, consistency, and safety.” – Michael Williams
The need for clear drill holes
Blocked drill holes can be costly and time-consuming, requiring extended efforts to install ground support or re-drill and re-charge ineffective faces. The Auger Drill Steel, with its full-length spiral, mechanically clears boreholes of obstructions, gravel, and broken ground throughout the entire drilling process.
Technical specifications and advantages
- Spiral design: Acting like a twist drill, the spiral flights mechanically clear waste and fractured ground. The hot-twisted, forged, and machined one-piece nickel steel construction offers superior strength and durability.
- Customisation: The auger drill steel is carburised and heat-treated to 55 Rockwell, with adjustable spiral pitch and length. Extension steels and increased diameters are available.
- Structural integrity: The spiral pattern aligns metal fibres, enhancing flexural, tensile, and compressive strengths. This design minimises vibration and deviation, ensuring faster, straighter, and cleaner drilling.
Benefits for resin bolting with Trajectaflex
The synergy between the Trajectaflex Resin Firing System and the Auger Drill Steel is particularly advantageous in difficult ground conditions:
- Cost efficiency: Reduces resin cartridge wastage and rupture-related costs.
- Cycle time reduction: Streamlines bolting cycles by minimising manual clearing and reworking of drill holes.
- Single-pass drilling: Ensures clear bolt holes in one pass, reducing overall drilling time.
- Maintenance reduction: Reduced resin capsule wastage, minimised boom movements, no re-drilling of blocked bolt holes, extended service intervals, equipment life and drill consumables.
- Safety and Handling: Minimises manual handling and reduces the risk of misalignment during post-drilling checks for hole blockages.
