Swing Angle Dector(SIRRAH)

SIRRAH is a sensor giving angle positions of a hoisting system fitted with an infrared transmitter : to use or sway and skewmeasurement. The coordinates are evaluated as plus or minus relative to the axis of  the detector. In its LS08 version, SIRRAH is improved for applications on container cranes of small height : sway measuring and load positioning on ground. It is waterproof and insensitive to the ambient infrared.  

Sway & Skew 

(SIRRAH)

USE

SIRRAH, fixed on the crane’s trolley, analyses the beacon position fixed on the hoist. It is the sway sensor function or positioning sensor X, Y of a load. Its high speed of measure enables itself to enter in a sway readjustment loop.
If the spreader is fitted with two infrared beacons and the trolley with two SI08, the crane computer can also regulate the skew movement of the load. 

PRESENTATION

SIRRAH is presented in a monolithical way, in a box including optics, electronics and the processor for the measurement control. A calculator or a PLC (not provided) can be directly connected to SIRRAH to enable the use with several softwares. SIRRAH is associated to one or several I.R. beacon to put on the spreader. It is independent from the sensor and synchronises itself automatically on SIRRAH.
