ABB designs and produces complete mine hoists in-house – the mechanical equipment, brake systems, electrical control and drive systems. It supplies various types of mine hoists, from friction to single and double drum hoists, plus shaft interface equipment, for productive hoisting processes.
The mechanical, electrical control and drive systems for ABB mine hoists are fully designed in-house.
Because ABB designs the mechanical and electrical equipment for a mine hoist in-house, it optimises the productivity and safety in the complete system. Its advanced engineering is supported by a quality management system that covers all aspects, from design to commissioning.
The company also offers long-term service and support for its mine hoist systems. With a global and local presence, there is always a skilled ABB service engineer close at hand to ensure the equipment is well maintained for maximum productivity. With more than a century of experience and a long list of over 700 active installations worldwide, ABB’s mine hoist systems provide proven, integrated technology, together with availability, reliability and safety.
Mike Davis, Global Product Manager for ABB’s hoisting business says, “We often supply stage winders to mining contractors during shaft sinking projects. Contractors may purchase stage winders along with a kibble winder or bucket hoist. In some instances, they procure the stage winder and keep it in their fleet for future projects.
“If we engage with mine design teams early on, the kibble winder can be sized for permanent duty requirements, saving time and costs as the project moves forward. We can also handle mine electrification and major switchgear installations. These are managed by another expert team within ABB, with the hoisting team handling the hoists and the electrification specialists managing the switchgear and related systems,” says Davis.
Jaco Truter, Technical Product Manager, Hoisting, at ABB, highlights that ABB’s compact stage winders, particularly those using the regenerative ACS800 drives, are designed for efficient and precise winding applications. The stage is kept level by either synchronising drum movement or by feedback from a level transducer on the stage. This ensures precise guided movement through the shaft.
Multi drum winders are controlled using a central AC500 PLC and central safety circuit. This ensures closely synchronised starting and stopping of all drums. Each project is risk assessed to ensure the appropriate safety functions are included in the design.
ABB mine hoist solutions provide a low lifecycle cost, high reliability and system availability, short project execution time and a single source of supply for the complete system, including service and spare parts. The company also offers its globally recognised engineering resources to conduct feasibility studies and provide conceptual solutions for specific mine hoist systems. It has access to an extensive global network of hoist experts.
