Miller Technology has appointed Becker Mining South Africa as distributors in Southern and Central Africa, of the new range of Relay electric mining vehicles, developed especially for the underground mining environment.

“The Relay is a new fully electric mining vehicle – purpose-designed for the mining sector -with a durable and modular construction and features for easy control and serviceability. This robust vehicle provides 1,550 Nm of torque and can safely carry a two-ton payload, with a maximum operating speed of 110 km/h, that is software programmable,” explains Nico de Lange, Senior General Manager, Energy Sales, Becker Mining South Africa.

The Relay has an advanced Rechargeable Energy Storage System (RESS) and is capable of being fully charged in under 20 minutes, for a 10-hour mining shift. If the topology of the mine is suitable, regenerative braking technology offers up to two hours of additional operating time.

The Relay is designed for on-board and off-board charging, through a Combined Charging System (CCS) type 2. These chargers are liquid cooled, with an IP65 rated enclosure that is sealed to protect the power electronics against dust and moisture.

This electric mining vehicle also offers reduced noise levels and advanced cooling and temperature monitoring capabilities. Other notable features for high performance and greater safety include fire suppression systems, programmable zone control facilities, integrated onboard diagnostics and comprehensive on-board data logging, with bidirectional data transfer via Wi-Fi or LTE networks.

The Relay’s safe methane monitoring system initially analyses for methane. If results are clear, the vehicle’s 24 V system is energised, enabling pre-start diagnostics. If methane is detected during service, the system will default back to the intrinsically safe system.

These electric mining vehicles are fitted with puncture-resistant segmented rubber tyres, with an open construction. In the event of shredded segments, each damaged segment can be replaced without having to remove the rim.
