Skew measurement with 2 sensors

 

Products of SIRRAH range enable measurement of sway and skew movements of the container on yard cranes in container terminals : RTG, RMG, OHBC.

Measurement is of higher accuracy when using 2 sensors.

Two SIRRAH sensors ref. SI08 enable the evaluation of view angles of each two beacons located on the crane’s spreader. The beacons are synchronized between each other through a special link cable.

SIRRAH, positioned downwards, are vertically situated in the trolley and the beacons are located upwards on the spreader. The two beacons have to be separated by a certain distance to assure a high precision.

A 4 or 5-meter distance is the best configuration, that means each beacon is to be installed at each end of the spreader. Each Sirrah sensor is situated exactly on the top of each beacon.

This 2-sensor solution allows a longer distance between the beacons and therefore a higher accuracy.

 

REQUIRED MATERIAL FOR THIS SOLUTION

 

2 SIRRAH sensors Ref. SI08 (LS08 Sensor included in BO35 protective housing including power and serial cables) + 2 infrared beacons Ref. BMU-04 + 1 link cable Ref. DRC3.
