Crane Sentry® Zone Manager Series

The Crane Sentry® Zone Manager Series models are manufactured and marketed by Laser-View Technologies for crane collision detection and zone control in 2 axis. Typical usages for the Crane Sentry® are to detect restricted zones in 2 axis.

By adding this model to your existing cranes, you can get access to zone management and add to your anti-collision safety efforts. Crane Sentry® is designed and manufactured in the USA.

Competitive Advantages

  • This is a MEASURING system, not a PROXIMITY device:
  • Competitive difference: You see what you are measuring- no guesswork!
  • Manufactured in USA by Laser-View Technologies using long range laser distance sensors
  • Modular, easily configurable; teachable color touch screen display
  • Economical approach to monitoring crane position, detecting potential collisions, and controlling zone activity.
  • Monitor bays up to 1640 ft long
  • Simple integration with your drive via our built in relay outputs

Crane Sentry® Zone Manager II

  • Restricted zoning/no fly zones
  • Dedicated relay outputs for bridge and trolley motion; slow and stop
  • I/O communications with machinery and processes below in the crane bay
  • Allow for up to 8 restricted zones
  • Considered a “field mod” for crane dealers, as it is easily retrofitted to existing cranes
  • Remote access capability from a smartphone or tablet (optional) in addition to the physical controller built-in on board

What They’re Saying

“The programming features are by far the easiest I’ve seen for this type of system.

Our customer immediately saw the value in the system and placed one on each crane that operates in close proximity to their presses. All in all I think it’s the best system on the market if you need zone management on your crane!”

Chris Hamrick, CEO of Protek Crane Solutions LLC
