Skew measurement with 1 sensor


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

SIRRAH sensor ref. SI08 enables 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, is vertically situated in the trolley and the beacons are located top wards on the spreader. The two beacons have to be separated by a certain distance to assure a high precision.

A 3-meter distance is the best compromise between measuring range and accuracy.
Two sensors can be used for higher accuracy.

1 SIRRAH sensor: 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.
