Dusty, wet, confined spaces mean devices such as power lines, plugs, and receptacles must be able to withstand the harsh and hazardous mining environment. Our AC mining connector devices can supply power to many different pieces of equipment which can run at low, medium, and certain high voltage states.

We’ve been servicing the North American mining industry for over three decades, starting on the coalfields of West Virginia and expanding into the largest mining services group in the USA today.

With 13 distribution centers and support offices located across nine states, mine operators and workers know they can rely on Carroll Technologies Group to provide the highest standards of safety and support available.

We even offer same-day delivery for a substantial range of electronic products, including our AC connectors, to ensure mining operations are constantly up and running nationwide.

AC Connectors for Use in Mines and Tunneling: Supplies

Ideal for channeling electricity from a permanent line or trolley wire to a piece of mobile equipment, our trailing cables are heavily insulated and protected against the harsh mining environment.

Carroll Technologies Group also supplies a series of high and low voltage AC power couplers for connecting multiple devices, and a range of plugs and receptacles for channeling an AC current.

Sourced from reputable suppliers such as Line Power Manufacturing and the SMC Corporation of America, we can guarantee mine operators high quality, durable products across the board.

SMC offers a range of AC servo sliders, designed to enable higher speeds and acceleration, and improve the vertical load capacity of equipment – these include ball screw drives and belt drives, at both high and regular rigidity, as well as support guides.

They also supply AC servo rods, such as the Dust and Drip Proof IP65, which includes a vent hold and fitting which balances internal pressure and prevents the entrance of dust and water.

Carroll Technologies Group stocks a wide range of power actuating products, trusted by over 800 mining companies across North America.

We pride ourselves on consistently delivering results across our varied portfolio of electrical equipment, and our MinerCare 24/7™ team can be contacted over the phone at any time to provide mine owners with the day to day support they need.

With Carroll Technologies Group, mine operators know they are always able to rely on us for advice and guidance on their electrical requirements and safety solutions.

VFDs are an essential component of all adjustable-rate electrical equipment, and guarantee safe and efficient operations in a hazardous mining environment.

Over 800 mines across North America put their trust in Carroll Technologies Group and our MinerCare 24/7™ support team to deliver effective solutions to their everyday challenges.

From cascade drives to mechanical gears, there are hundreds of motorized applications which could benefit from the added motor control of a VFD.

Variable Frequency Drives in the Mining Industry: Reducing Energy Consumption

A VFD allows mines to reduce their energy consumption and costs, as machinery no longer has to constantly run at full speed.

Fewer operational mistakes are made as equipment is always running at its most efficient level, extending its functional life and reducing the need for product maintenance.

This comes with the added benefit of reducing a mine’s greenhouse gas emissions. Variable frequency drives also improve safety and comfort in the working environment, through giving miners more comprehensive control over their equipment.

We offer a range of low and medium voltage VFD products and systems from Benshaw, ranging from multi-purpose microdrives to turnkey drive control systems.

These applications are all reliable and easy to use, with intuitive operator interfaces.

Benshaw offers a wide range of drive packages, from 1-700 horsepower, able to support even the toughest variable speed applications.

Mine operators can also order custom drives for any unique needs the standard Benshaw range doesn’t cater for. This means a VFD is an option for an extensive range of motorized devices, offering your choice of disconnect, bypass, line and load reactor, and control options.

Products such as the S4 Series washdown duty drive can withstand even the harshest environments, designed to operate in wet, dirty, or corrosive environments without a hitch.

Their double labyrinth seals prevent things like dirt, oil, and water from entering and damaging the drive, and they can withstand a high-pressure washdown of up to 1,000 psi.

The SG Series of high-performance sensorless vector drives are also ideal for the mining environment, designed for the most demanding, hard to start applications.

The flexible power stack allows the user to apply the VFD to heavy and standard duty loads, as well as variable torque loads. While simple and easy to use, the SG series drives can be configured to meet the needs of a wide range of mining devices.

An MCCB is a vital piece of apparatus for electricals where load current will exceed the capability of a miniature circuit breaker, and is essential for both the safety of mining staff and the longevity of the equipment they use every day.

Molded Case Circuit Breakers for Use in Mines and Tunneling: Risk Prevention

MCCBs are triggered in cases of thermal overload, short circuit, and ground faults. When these events occur, the MCCB will use its electromechanical trip units to safely halt the flow of electric current. This helps to minimise a mine’s risk of fire, explosion, or related hazardous events.

Carroll Technologies Group offers the widest range of electronic equipment available to mine owners across North America, including a range of mining MCCBs from Eaton.

Eaton Molded Case Circuit Breakers

Both new and factory serviced, each mode is a high-quality product which guarantees mine owners efficient running and a safe working environment for their employees.

Eaton’s 40-year commitment to the mining industry means their MCCBs can be relied upon to provide the very best in circuit-breaking technology.

The products have been extensively tested for reliability in hazardous mining environments, designed collaboratively with engineers from several reputable coal companies.

Eaton’s mining Molded Case Circuit Breakers are designed to protect all sizes of trailing cable, with minimal panel design and inventory requirements, and come in seven frame sizes to fit your individual needs.

The majority of units can also be installed in the field, allowing for simple on-site customization and replacement.

Field testing is also straightforward, as each MCCB includes a convenient built-in test port, compatible with the 120 Vac test kit.

Likewise, mechanical testing couldn’t be easier, with a push-to-trip button on each unit which can be triggered to confirm functionality during routine maintenance.

Eaton’s 310+ electronic trip unit technology means these MCCBs are triggered faster than microprocessor-initiated instantaneous trips.

The peace of mind delivered by these technologies is second to none, guaranteeing “faster than instantaneous” clearing times and enhanced safety measures.

Maintaining Your Mining Circuit Breakers

With an Eaton MCCB, you’ll always be able to visit a Breaker Service Centre (BSC) to maintain your device.

If it maintains minor physical damage or general wear and tear, BSC staff will be able to restore your device to full functionality. Should a device be beyond repair, Eaton offers credit toward the purchase of a new MCCB in exchange for the old model.
