Competitive Advantages

Crane Sentry® Lite is a measurement  device and not a proximity sensor, so you can reliably detect distance between cranes by entering the value numerically.

• Connects to up to (2) laser distance sensors
• Simple dual line display shows set points, live readings, and error codes
• Enter set points by  keying in values
• Available operating modes:
  • Distance minimum/maximum
  • Crane to wall or crane to crane
• (2) relay outputs per laser
• 98 ft / 30 m range
• 110 VAC/220 VAC single phase power required;  control box self-powers the connected laser sensors
• Polycarbonate wall mount sealed enclosure with clear window

Crane Sentry® as an all in one Collision Detection System

Commonly referred to as anti-collision, most competitor’s basic systems provide a laser displacement sensor, relays, and terminal blocks sold as a package. The sensors act primarily as proximity sensors, in which you teach a stop and possibly a slow limit. Most sensors require a retro-reflective target, which if it gets dirty, requires cleaning to operate. 

The Crane Sentry® Lite, as our entry-level collision detection product, includes some of the key features we are known for, but in a lower-cost package and with the only basic functionality needed for simple collision monitoring.

Crane Sentry® Lite Key Advantages Over Competition: 

• No reflector required for operation
• Visible red eye-safe laser spot
• Ability to back away from near crane or wall in high speed with optional relays
• Built-in error handling algorithm identifies an error from an out of range condition
