Crane Sentry® External Alarm Kit for Crane Safety Systems

Description

Key Features

• Multi tone programmable electronic alarm (LVMT4-115-SBOX) (110 VAC)

The Crane Sentry® External Alarm Package is an add-on or integrated component of a comprehensive crane safety and collision detection system, primarily from Laser-View Technologies (who manufacture the Crane Sentry line). Its main purpose is to provide highly visible and/or audible warnings to personnel on the ground or in the vicinity of the crane, supplementing the alarms given to the crane operator within the cab.

Here’s a description of what it typically entails:

Description:

An external alarm package extends the warning capabilities of the Crane Sentry system beyond the operator’s cab. While the operator receives visual and audible cues inside, an external package ensures that other workers, supervisors, or even other crane operators in shared areas are also alerted to potential hazards. This is crucial in busy industrial environments where multiple cranes might operate in proximity, or where personnel are working near crane paths or heavy lifts.

These packages often consist of robust, industrial-grade components designed to withstand harsh outdoor or factory conditions.

Components and Features often included:

• Strobe Lights/Beacons: High-intensity flashing lights, typically red or amber, that provide a clear visual warning over a wide area. These are particularly effective in noisy environments where audible alarms might be difficult to hear.
• Audible Sirens/Horns: Loud, piercing alarms or horns that can cut through industrial noise to alert workers. These can be configured for different tones or patterns to signify different types of warnings (e.g., pre-alarm vs. critical alarm).
• Combination Units: Many external alarm units combine both visual strobes and audible sirens into a single device for maximum impact. These outputs are used to trigger the external alarm package when specific conditions are met (e.g., crane entering a restricted zone, approaching another crane, reaching a pre-set distance from an end-stop).
