Gearbox Refurbishment

We provide gearbox refurbishment services to restore your critical mining equipment to optimal performance. Whether it’s for a drilling operation, haulage system, or processing plant, our expert servicing helps extend the life of your gearboxes, reducing downtime and ensuring efficient operation.

Mining Equipment Support

Our expertise extends to components used in mining equipment such as crushers, excavators, shovels, and haul trucks. We offer precision gears and splines for these essential machines, ensuring they operate efficiently and reliably in challenging mining environments. We also provide refurbishment services to help maintain and extend the life of your equipment.

Commitment to ISO 9001 Quality Control

As an ISO 9001-certified manufacturer, we adhere to stringent quality management processes throughout production. This ensures that all our gears, splines, and refurbished units meet mining-specific standards, providing exceptional performance and reliability in the demanding conditions of the mining industry.

Key Mining Gear and Spline Types

  • Spur Gears – Ideal for applications requiring efficient power transmission between parallel shafts.
  • Helical Gears – Designed for smooth, quiet operation in high-speed, heavy-load applications typically found in mining equipment.
  • Bevel Gears – Crucial for transmitting power between shafts set at various angles, making them essential for mining machinery such as crushers and conveyors.
  • Worm Gears – Compact and efficient, perfect for tight spaces requiring high torque and minimal maintenance in mining equipment.
  • Planetary Gears – Used in high-efficiency, lightweight power transmission systems for excavation, transport, and processing equipment in mining operations.
  • Splines – Vital for transferring torque between connected components, ensuring secure and reliable connections for critical mining systems, such as crushers, haul trucks, and processing plants.

Materials Tailored for Mining Durability

Our gears and splines are crafted from advanced, high-performance materials like stainless steel, titanium, and hardened alloys. These materials are selected to withstand the harsh conditions found in the mining industry, including high pressure, extreme temperatures, and constant mechanical stresses.

Precision Manufacturing for Critical Applications

We utilise precise manufacturing techniques in gear cutting, spline production, and finishing to meet the strictest tolerances. Every part is designed to endure the unique stresses of mining operations, ensuring reliable performance and durability in the field.
