US-based equipment manufacturer Caterpillar has introduced the Cat DET system to make mining operations sustainable.

This solution is capable of transferring energy to large diesel-electric and battery-electric mining trucks while in operation.

It is equipped to transfer energy to vehicles as they navigate the mine as well as charge a machine's batteries while in motion, which may significantly boost machine uptime and operational efficiency.

The Cat DET system consists of a power module that converts energy from the power source of a mine, an electrified rail system that transmits the energy and a machine system that transfers the energy to the truck's powertrain.

This integrated design is said to support enhanced flexibility and adaptability to various mine site layouts including those with high-speed and curved haul roads, which could lead to increased productivity.

The system's mobile rail solution can be tailored to fit specific site requirements. It features a connecting arm that can be deployed on either side of a truck and is compatible with multiple truck models, offering versatility to meet diverse operational needs.

This new solution will be showcased at MINExpo 2024 in Las Vegas from 24–26 September 2024.

Caterpillar resource industries group president Denise Johnson said: “We believe Cat DET provides a technological leap for the mining industry. Our team of innovators designed this system to provide immediate benefit to miners who want to lower their operating costs and greenhouse gas emissions today while also creating flexibility for the future.”

Furthermore, the Cat DET system will be integrated with the Cat MineStar Command for hauling solution, combining autonomous and electrification technologies to deliver a comprehensive site solution.

The integration could potentially streamline operations and enhance the overall efficiency of mining activities.

Caterpillar senior vice-president Marc Cameron explained: “We believe mine sites will benefit from enhanced efficiency with the integration of electrification and automation. When combined, these technologies will help miners achieve production targets while simultaneously managing energy demands.”

Last year, Caterpillar and Orica signed a memorandum of understanding to explore opportunities to integrate some of their key technology offerings in mining.
