Power Line Warning System

huge logo.png

The Voltek NS detects the presence of nearby overhead power lines by sensing the E-field produced by the power line. This system has easy to use controls to interact with the equipment operator to avoid dangerous contact. The system can be integrated with either the E-stop or hydraulic systems of your machinery to stop the movement of your equipment or shut it down entirely. The sensitivity of the Voltek NS is adjustable to accommodate practically and job site or situation.

  • Detects 50Hz (foreign) and 60Hz (domestic) overhead power lines greater than 2500V

  • Intuitive user interface

  • Optional integration into equipment Estop or other controls

  • Backlit display

  • IP67 rated enclosure (dust and water proof)

  • Operates on 12-24V DC

  • Adjustable sensitivity 

  • 120db external alarm

  • Uses the wire antenna running the length of your boom to detect power lines (lengths available from 15-200'-trim to desired length)

  • Best suited for fixed boom/mast machinery (non-telescopic) such as: excavators, concrete pump trucks, hydrovac trucks, pipelayers, lattice-boom cranes, etc.

Principles of Operation:

Overhead power lines produce an electric field (E-field). The strength of the E-field is largely dependent upon the voltage of the power line and the distance from the power line. The higher the voltage-the stronger and larger the E-field surrounding the line. The Voltek NS measures the relative strength of the E-field and translating that data into usable information for the operator.

Remote Control for NS & Dualtek

The Spotter gives you access to all the controls of the NS at your fingertips. Designed for certain applications where the NS is out of immediate reach (such as concrete pumps, remotely operated cranes, etc.) The Spotter will give you complete access to your power line warning system.

  • Remotely controls the Voltek NS or Dualtek (perfect for pump operators or other situations where access to the NS/Dualtek is not readily available)

  • Waterproof enclosure (IP68)

  • Backlit display

  • 500’+ transmission range

  • 12+ Hour run time between charges

  • WARNING button sounds alarm on the Voltek NS for any emergency situation

  • SHUTDOWN button activates the shutdown feature on the Voltek NS for any emergency situation

Power Line Warning with Limit Switch Integration

The Dualtek offers power line detection but adds limit switch functionality to create auxiliary safety controls for your equipment. For hopper grate shutdown on concrete pumps to rotational movement on excavators and anything in between, the Dualtek provides full control of your equipment.

  • All the features of the Voltek NS Power line warning system plus limit switch integration

  • Alerts operator when limit switch is activated

  • Optional siren activation when limit switch is triggered

  • Example limit switch integration applications:

    • Concrete Pump hopper disable​

    • Boom control functions

    • Load limiting for side booms

  • Works with up to three limit switches​
