GIGASENSE® II is an anti-collision system / collision avoidance system for track bound cranes (EOT) or similar equipment in tough industrial environment. The GIGASENSE anti-collision system is easy to install, robust, maintenance free and comes with built in self diagnostic functions to monitor the system. The microwave technology makes it especially suitable for steel-works, harbors and the like environments.
One crane uses an A-unit and one crane uses a B-unit. A- and B-units each consists of an active antenna and a relay box. The antenna sends a Microwave signal to the opposite unit. By using SFCW (Stepped Frequency Continuous Wave) radar, the distance and relative speed are calculated.
One transponder without the relay box can be used together with a complete A- or B- unit on the crane. The output relays switches at preset alarm limits to reduce speed and stop the crane movement. Settings and readout of parameters are easily accessible via a display and push buttons in the relay box.
The relay box contains three relays:
Relay 1 = Warning (speed reduction) or flashing light.
Relay 2 = Stops crane movement.
Relay 3 = Failure/unidentified object alarm.
One analogue output, 4-20mA is available for e.g. remote display.
Avoids crane accidents and protects property and production. Designed to work in the toughest conditions such as in steel works, harbours, mines etc. The signal is very hard to disturb, the A- and B units use different frequencies, different polarization of the Microwaves and a ”fingerprint” radar reflection. The function has a backup capacitor in case of power failure. The anti collision system is not disturbed by rain, dust/metal particles, fog or sunlight.
Working distance
2 – 40m, the maximum working range varies for different frequencies from 25m to 50m due to restricted output power
Speed range
0.05 – 3 or 5 m/s relative speed between two moving cranes, depending on frequency
Accuracy
Typical alarm limit accuracy ±1 m. Actual alarm limit accuracy may be affected by travel speed, distance, installation, and environmental factors. Speed compensation (SPD) can be used to trigger alarms earlier at higher speeds.
Relative Speed Compensation
Speed compensation (SPD) can be used to trigger alarms earlier at higher speeds.
The alarm limits can be compensated from 20–1500% for different speeds.
Relay outputs
Three potential free relays (250 VAC / 8A).
Temperature range
-25°C to +70°C.
Supply voltage
24 VDC (alternative Voltages available as option). Transponder unit 12 VDC.
Transmitter Frequency
9.4 – 10.6 GHz (country specific).
Gross weight & dimension
System incl. packaging (Unit A + Unit B): 13.5 kg / 510x510x290 mm
Typical alarm limit accuracy ±1 m. Actual alarm limit accuracy may be affected by travel speed, distance, installation, and environmental factors. Speed compensation (SPD) can be used to trigger alarms earlier at higher speeds.
