Crane Monitoring System
The Crane Sentry product line is manufactured and marketed by Laser-View Technologies for crane collision detection, zone control, and positioning applications. Crane Sentry, the crane collision detection sensor system, is designed and manufactured in the USA and utilises laser distance sensors.
What does Crane Sentry do?
Typical usages for the Crane Sentry are to detect bridge to wall and bridge to bridge collisions, define restricted zones, and for positioning.
Crane to Crane – collision detection
- Provide up 6 programmable relay outputs for functions like slow and stop
Crane to Wall – collision detection
- Combine with crane-to-crane protection to detect end stops
Zones – 1 axis
- Alert workers or machine centres that crane is on a zone
- Rows of machines
- Walkway
- Can be combined with crane-to-crane collision detection
Zone Control – 2 axes
- Detect rectangular areas, such as machines or in plant offices
- 8 relay outputs output to bridge and trolley controls to alert the motor drive of proximity
Advanced Overhead Crane Safety & Reliability
This line takes the entry-level anti-collision detection system a step beyond to include a live colour display, touch screen controller, and teachable and programmable relay alarms in a cost competitive package.
- Crane Sentry operates indoor/outdoor with an accuracy of up to 1/8” (3 mm).
- Laser-View Technologies also offers special accessories to add functionality:
- Wireless I/O modules
- Override capability
- Visual and audible signalling
- Connection modules between crane sentries
- Secondary panels for interfacing with 250 VDC cranes
The Crane Sentry Family
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.
Crane Sentry
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:
- Max/Min distance
- Zone control
- Skew alarm
- Up to 1640 ft / 500-meter measuring range when equipped with our target plate – contact us for long bay applications
Crane Sentry Jr.
- Connects to up to (2) laser distance sensors
- Simple and intuitive colour touch screen controls show set point and live readings
- Program set points with simple TEACH button or key in values
- (6) Mechanical relay alarm outputs
- (3) settable distance alarms (collision monitoring) per laser
- 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 Lite
Crane Sentry is a measurement device and not a proximity sensor, so you can reliably detect distance between cranes by entering the value numerically:
- (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
Crane Sentry Zone Manager Series
- Connects to up to (2) laser distance sensors
- Zone controls (lock out activity in a zone) for up to (8) configurable zones
- Simple and intuitive colour touch screen controls show set point and live readings
- Program set points with simple TEACH button or key in values
- (8) Mechanical NO/NC relay outputs (8A)
- 110 VAC/220 VAC single phase power required – control box self-powers the connected laser sensors
- Polycarbonate wall mount sealed enclosure with clear window
Available operating modes:
Crane-to-wall/-crane | ||||
Collision monitoring | ||||
Skew (2 lasers) | ||||

Zone management (2-axes) |
Why upgrade to the original Crane Sentry or Zone Manager?
Although Crane Sentry Jr provides an unrivaled combination of features and value for everyday overhead crane position and collision detection applications, not all applications are “everyday” applications. Crane Sentry and Crane Sentry Zone Manager are available with the following upgraded features and options:
Range | ||||
Up to 50 m (no reflector) | ||||
Up to 65 m (no reflector) | ||||
Up to 500 m with reflector | ||||
Outputs Range | ||||
6 configurable alarm outputs | ||||
10 configurable alarm outputs | ||||
Optional relay outputs | ||||
Advanced zone management | ||||
Measuring rate up to 20 Hz | ||||
Integrated heater option | ||||
Supports up to 2 lasers | ||||
Quick aim & set installation | ||||
Simple color touch screen | ||||
Value to feature ratio |
