Global growth and infrastructure development depends heavily on mined natural resources such as minerals, metal ores, and coal. Open-cut and underground mining operations require an array of powerful electric machines to do the heavy work and minimize emissions. Specialized energy and data transmission systems must provide safe and reliable power in dusty and sometimes explosive environments, and often must withstand high vibration and G-forces. Due to their enormous size and power, mining machines must work continuously in very demanding conditions, and often require voltages up to 36kV. Large scale digging and excavation equipment for open-cut mines, such as electric power shovels and large scale conveyors, require trailing, level-wind cable reels and slip rings at the rotating joints. Drill and blast equipment used for hard rock and underground mining require rugged, compact cable management systems. Mobile power is also needed for shotcrete machines, blast-hole drills, ceiling bolters, and other underground equipment. Battery operated underground transfer cars need flexible charging systems.
For round-the-clock mining operations, Conductix-Wampfler offers field-proven, customized solutions for all types of mining equipment and machinery. Our global network of sales and engineering facilities and strong after-sales and servicing teams support our customers in their global activities. Motor-Driven Cable Reels – powered by electric or hydraulic drives to manage long-travel power cables for large open-cut mining excavators and drill and blast machines. Our motorized reels include robust and reliable slip ring assemblies to provide continuous power and are also in use to handle cables for transfer cars and other raw material transports.
Cable Festoon Systems – extremely reliable and durable – to handle machine movements (horizontal or vertical) for gantry cranes, conveyors, and similar equipment and to manage cables for machines such as conveyor belt tensioning units. Special cable trolleys can run on square, “diamond” track for dusty and harsh applications, such as conveyor belt tensioning units.
Energy Guiding Chains – are ideal for managing cable and hoses that power moving machine elements, such as telescoping booms on roof bolters, shotcrete machines, and other mobile equipment.
Spring-Driven Cable Reels – compact, stainless steel spring-driven cable reels can manage cables used for vertical or horizontal movements of mining machine elements
Conductor Rails – highly durable and corrosion resistant, supply power to transfer cars and other conveying equipment. Special conductor bar systems charge battery-driven underground mining cars and allow vehicles to engage when charging and disengage when operating.
Jay Radio Remote Controls – offer a safe way of operating or monitoring machines from a distance. The comprehensive range of industrial and safety radio remote controls offers countless solutions to adapt to an extensive number of mining applications.
