The Crane Sentry® product line is manufactured and marketed by Laser-View Technologies for crane collision detection, zone control, and positioning applications. Crane Sentry® is designed and manufactured in the USA and utilizes laser distance sensors.
Typical usages for the Crane Sentry® are to detect bridge to wall and bridge to bridge collisions, define restricted zones, and for positioning.
This line takes the entry level anti collision detection system a step beyond to include a live color display, touch screen controller, and teachable and programmable relay alarms in a cost competitive package.
Crane Sentry® operates indoor/outdoors with an accuracy of up to 1/8” (3 mm).
Laser-View Technologies also offers special accessories to add functionality:
The Crane Sentry® family is growing and consists currently of several distinct product versions.
Combine any of our standard modular packages to make an advanced crane collision detection system from standard parts.
This is a full featured product that can be used as an anti collision sensor for cranes. Crane Sentry® accepts up to (2) laser distance sensors that can be configured to monitor several user-selectable conditions with up to (6) programmable outputs:
Crane Sentry® is a measurement device and not a proximity sensor, so you can reliably detect the distance between cranes by entering the value numerically:
This is a specialized version of our standard product that is used to provide semi-automation to a crane or 2 axis material handling system. This unit accepts (2) laser distance sensors that can be configured to automatically move the trolley and bridge to predetermined locations. The locations, including home, and a safe travel aisle can be taught with a single button:
Usage of hoists for lifting loads in industrial applications has inherent risk, requiring the need for safety precautions. The Crane Sentry® Hoist Side pull is capable of detecting excessive side pull on a wire rope hoist and can be configured to alert the operator of the condition or disable functions. The model Laser-View Technologies offers is the omni-directional version (a combination of X and Y). This solution offers:
This is an extended version of our standard product that can be configured to monitor restricted zones around injection molding machines, in which robot arms can extend above the bridge. The system detects collisions and keeps the robot arms from hitting the crane when the crane is present. This unit accepts up to (2) laser distance sensors that can be configured to monitor several user selectable conditions with up to (10) programmable outputs:
This is a specialized version of our standard product that is used to keep multiple bridges on the same runway or adjacent runways supported by the same column structure from being too close when there is a load limit concern.
Our Advanced Wire Rope Hoist Monitor offers a comprehensive solution for your crane operation needs. It provides the safety, reliability, and high performance of our Crane Sentry® side pull monitoring while providing continuous performance updates. The Advanced Wire Rope Hoist Monitor includes these safety features:
Usage of hoists for lifting loads in industrial applications has inherent risk, requiring the need for safety precautions. The Crane Sentry Hoist Side Pull is capable of detecting excessive side pull on a chain hoist and can be set to alert the operator of the condition or disable functions. This solution offers the following features:
