Integrated hoist systems, project management and engineering services
Hepburn is the only company that designs complete hoisting systems for all types of hoists. We are a single source for hoisting projects and have project management, mechanical and electrical engineering groups in a single location.
3D modeling CAD software and finite element analysis
Hepburn design engineers work with the latest design software including 3D modeling CAD software and finite element analysis, and apply their skills to produce advanced hoists with a solid basis in proven design.
Custom-built hoist systems
Hepburn hoist designs have focused on hoist reliability, availability and performance. Over 50 years of design development has culminated in modern, reliable and efficient designs. The latest engineering and analysis tools are used with every design, allowing us to custom build to the customer’s requirements.
Electrical drive and control systems
Hepburn supplies complete drive and control systems for all sizes of AC and DC mine hoists. It provides the most modern AC drive systems, capable of unity power factor and compliant to IEE519.
Our electrical control systems use a PLC platform most suited to the customer, ensuring integration with mine-wide maintenance and information systems.
HMI systems for mine hoisting
Hepburn has the most advanced HMI systems, developed exclusively for mine hoisting. Our hoisting information systems allow production and availability databases to be viewed remotely using a web browser.
The Hepburn hoist manager HMI and web-based Hepburn hoist reporter are available for every hoist control system.
Shaft sinking hoists and winches
Hepburn has a unique range of shaft sinking hoists and winches. Our shaft sinking hoists are of a modular design and can be easily assembled and disassembled. Plug-in control system cables allow for easy system installation and startup.
Hepburn’s range of platform (stage) winches are available in single units, which can be synchronized in groups of up to four for a maximum combined line pull of up to 300t. This flexibility allows a combination of winches to be selected appropriately to a particular shaft.
