Harbour crane anti-collision system BoomRanger®

radar

Highly effective protection for container ship bridges and superstructures against collisions with port cranes. - Extremely wide beam angle - Optimized range for application - For moving and stationary targets The BoomRanger® radar scanner (CRAT20-150/11ST), an FMCW radar, operates in the frequency range of 24.000 - 24.250 GHz. The antenna characteristic is 150° (±75°) horizontal and 11° (±5.5°) vertical. BoomRanger® was specifically developed as an anti-collision system for collision protection in the area of fast-moving port cranes. The radar scanner system detects moving and stationary objects up to a distance of 25 m. The adjustable distance is set in 1-meter steps. Object detections are reported via open-collector outputs. BoomRanger® has 3 outputs that can be used, for example, as braking or stop functions. They can be programmed to the values required for the respective application. The 3 outputs are led to a 5-pin RSF4 standard connector. - Extremely large detection range - Insensitivity to environmental influences - Wide temperature range - High protection class - Robust housing Special mounts from the accessory program are helpful for easy installation. Due to their physical properties, radar scanner devices MUST NOT be used for personal protection or emergency stop functions. Technical Data Mechanical Design - Weight: approx. 650 g - Material: Housing base: ALg, black anodized - Housing cover: POM plastic, black colored - Protection class: IP 67 - Housing dimensions: 100 x 100 x 42 mm - Mounting holes / housing back: 4 X M4 threads, 10 mm deep, square arrangement: 82 x 82 mm Electrical Design - Supply voltage: 10 .... 30 VDC - Current consumption: typ. 130 mA, plus current for the open-collector outputs - Output: 3 open-collector outputs with 50 mA each - Connection: 5-pin connector M12x1, RSF4 compatible - Transmission frequency: 24.000 .... 24.250 GHz - Transmission power: < 20 dBm (EIRP) max. - Antenna characteristic: 150° (±75°) horizontal and 11° (±5.5°) vertical - Distance detection: 1 m .... threshold (adjustable in 1 m steps from 2 - 25 m) - 0 - 1 m is not evaluated, - 2 - 4 m minimum speed less than 1 cm/sec (0.6 m/min) required - 4 - 25 m also works with stationary targets - Response time: < 50 ms - Hold time of outputs: approx. 1 sec - Readiness delay after switching on: approx. 1 sec - Operating temperature: -40 .... +85 °C - Storage temperature: -40 .... +85 °C Application Example Due to its detection zone and its design for rough applications, the BoomRanger® radar scanner is ideal for protecting container ship bridges from collisions with port cranes. Reliable even in difficult weather conditions, such as dense fog, the BoomRanger® is superior to laser sensors in this application area. - Extremely large detection range - Insensitivity to environmental influences - Wide temperature range - High protection class - Robust housing
