Becker Mining SA introduces tri-technology PDS
Becker Mining South Africa’ s latest patented tri-technology proximity detection systems( PDS)— which range from a simple, low-cost single technology system, to integrated multi-technological solutions— encompass all aspects of the most advanced mining communications and technology.
“ Becker’ s patented tritechnology point of detection system is the only system available globally that combines three technologies— UHF, radar, and electromagnetic— into one scalable system,” says senior general manager: Electronics, Andrew Trentelman.
The tri-technology tag, which supports accident investigation and multimode operation, is compatible with Becker’ s tagging systems and communication networks. This tri-axis electromagnetic receiver ensures reliable detection by the system, regardless of the tag or miners’ position.
This system consists of a customisable caution zone, warning zone, and critical zone, with detection zone threshold distances set according to specific requirements, covering small and large vehicles. Bidirectional notification and early warning messaging alert vehicle operators and personnel to the presence of people and vehicles.

mechanisms for operators, including cabin lighting and alert tones that are selected to suit exact requirements. Advanced self-diagnostic functionality provides continuous monitoring of all connected peripherals to ensure equipment is functioning correctly. The operator is immediately warned if a device stops responding to the PDS controller.

ContiTech enhances vertical lift capabilities
As South Africa’ s mining industry continues to seek leaner, more energy- and operationally efficient ways of getting ore from the ground, ContiTech’ s Pocketlift vertical lift conveyor not only offers underground miners the ability to lift much larger quantities of material over far higher vertical distances than conventional skip hoists, but does so with a third of the energy requirements per metric tonne.
Pocketlift is an evolution of the company’ s well-known Flexowell belt, a belt that made its name in economic, high-efficiency up- and downhill bulk material conveyance. Pocketlift replaces the‘ compartments’ of the Flexowell with fabric-reinforced rubber pockets to deliver a conveyor belt that can lift material loads at vertical heights of up to 700m. The pockets are available in different widths to achieve continuous load throughputs of up to 6 000m 3 / hour.
“ Across the world, mining companies have been able to multiply their conveying output by adopting Pocketlift technology,” explains Friedrich Litz, innovative products
Pocketlift is a game changer in underground mining, achieving throughputs up to 6 000m 3 / hour with just one-third of the energy requirements of conventional skip hoists. manager at the ContiTech Conveyor Belt Group.“ Its small horizontal footprint and low intrinsic weight means it can be deployed in very small mine shafts— in many cases existing ventilation shafts can be used— helping miners reduce civil-based costs. In terms of energy, a ton of material lifted 100m is less than 0.3kWh— far below average.”
While the Pocketlift is an evolution of the performance of the Flexowell belt, Flexowell remains a popular, highperforming option for vertical bulk materials conveying in a wide range of industries.
“ The FleAxowell belt is a critical part of operations in more than 60 000 installations across the world,” Litz continues. It consists of compartmentalised pouches with pleated sides, mounted on a cross-rigid base belt with horizontal textile and / or transverse steel cord reinforcement. It can efficiently convey lump sizes up to 400mm in size, and be used on a maximum vertical lift height of 400m, with a maximum throughput of 6 000 tonnes per hour.
Both Flexowell and Pocketlift belts can be customised with the full range of ContiTech’ s cover compound technologies as required by application and application environment. ContiTech South Africa supports these belts with the full range of belt services, from calculation to engineering( basic and detailed), consulting, field splicing, and aftersales service.
The Pocketlift system can be used in narrow shafts and can cope with height differences of up to 700m.
