The Certified Jumbo Jack Leg Stands – E2275-0058 from ELM Engineering are precision-fabricated support stands designed to provide secure and stable support for jumbo drill equipment during maintenance operations in underground mining and tunnelling environments. Engineered for reliability and operator safety, these jumbo jack leg stands are a critical element of safe maintenance procedures for heavy drilling machines.
Weighing just 13kg and built to stand up to the mechanical and environmental demands of underground operations, ELM’s stands reduce risk by providing consistent, load-rated support for jack legs when equipment is elevated for inspection, servicing, or component replacement.
Purpose-Engineered for Underground and Mining Use
Underground mining presents unique challenges including confined spaces, uneven terrain, and demanding service conditions. ELM Engineering’s underground jumbo stands are manufactured from high-strength structural materials with a focus on stability, durability, and ease of use in these environments.
The stands are engineered to engage securely with the base of jack legs, supporting the equipment safely and minimising unintended movement. This makes them ideal for maintenance tasks such as:
-
Servicing hydraulic systems
-
Inspecting or replacing drill components
-
Conducting boom and mast maintenance
-
Performing scheduled maintenance checks
-
Supporting equipment during tyre or track work
By providing a reliable support solution, these mining jack stands help protect maintenance personnel and minimise the risks associated with improvised or non-certified support methods.
Robust Construction and Performance
The jumbo leg stands offered by ELM Engineering are built to deliver consistent structural performance under load. Key technical attributes include:
-
High-strength fabrication: Built from heavy-gauge steel with precision welding to withstand compressive forces encountered during maintenance tasks.
-
Stable support footprint: Designed to sit securely on uneven underground surfaces, with geometry that resists tipping or shifting when in use.
-
Durable finish: Industrial coatings and corrosion-resistant materials help extend service life in abrasive and high-moisture underground environments.
-
Consistent load support: Engineered to maintain structural integrity throughout repeated use cycles, reducing maintenance downtime and replacement costs.
These characteristics make the mining leg stands suitable for both underground drive maintenance and above-ground workshop environments, delivering versatile support wherever jumbo drills are serviced.
Practical Design for Maintenance Efficiency
ELM Engineering understands that maintenance workflows in underground mining must be efficient and predictable. The jumbo jack leg stands are designed with features that help support rapid deployment and straightforward engagement:
-
Optimised engagement geometry promotes secure seating under the jack leg base.
-
Compact footprint allows placement in tight underground workings without interfering with other equipment.
-
Balance between strength and portability ensures stands can be maneuvered by service crews without mechanical assistance.
-
Clear identification for stand type and rated application improves procedural compliance.
This practical design approach enhances operational safety while enabling maintenance teams to focus on core tasks with confidence.
Applications Across Multiple Maintenance Scenarios
These jumbo jack leg stands are widely used in heavy duty maintenance scenarios, including:
-
Underground drill rig servicing
-
Exploration and development headings
-
Drill component change-outs
-
Geotechnical and structural inspections
-
Scheduled and unscheduled maintenance shutdowns
Their adaptability and ease of use make them an essential tool in the maintenance repertoire of mining contractors, workshop technicians, and fleet service teams.
Safety and Compliance
ELM Engineering places a strong emphasis on safety and compliance. The Certified Jumbo Jack Leg Stands – E2275-0058 are manufactured to meet rigorous quality standards, with consistent testing and verification to ensure each stand performs as expected under load. Using certified mining jack stands in place of ad-hoc supports reduces risk and aligns with workplace safety protocols commonly mandated by mining operators and regulatory authorities.
