  • By giving the crane operator a convenient and effective means to warn and alert other workers near the load position, SkyHorn is the most effective tower crane operator horn.
  • By positioning our horn on the block instead of the operator cab, SkyHorn supplies workers with the ability to audibly locate the crane’s active load throughout the entire day.

The problems with a horn located at the operator’s cab:

The problems with a horn located at the operator’s cab:
  • 1

    The distance of the standard warning horn from the load position does not warn of the load’s location.

  • 2

    Compounding noise renders the horn at the cab barely audible and thus ineffective

  • 3

    Workers are unable to audibly determine the load’s position.

  • 4

    The operator should have control to provide enough time for adequate notice.

    • A simple whistle or an air horn is not in the operator’s control, nor does it properly warn workers of overhead loads.

This is a step forward to save operations... been doing this almost 20 years and believe me makes a huge difference.

Christian Michael

“I honestly do not think I could do another job without one”

Chris Hunt

13 year TC operator

“It makes everybody’s job easier, period.”

Bruce Harbin

37 year TC/ mobile operator

“Some of the main problems on construction sites has always been not being able to hear tower crane horns, now, you can hear where the block is.”

Vincent Thomas

5 year carpenter

“Sometimes the operator only uses the horn on large picks. I wish he would use it on every pick because the risk to us, being below the load, is a constant worry.”
