Rayco-Wylie Systems, Sainte-Foy, Quebec, Canada, will introduce a wireless load indicator (W3380) and a wind speed indicator (R180) at ConExpo 2011 in Las Vegas, Nev. The W3380 and R180 will both contribute to a safer work environment for crane operators by providing essential information such as load on hook, boom angle, length, and wind speed.
After months of research and development, the wireless indicators proved to be accurate and consistent in the field. Developed to reduce cost and installation time, the W3380 and R180 are pre-calibrated before shipment. Their sensors can be replaced quickly and easily without a complete system calibration.
“The systems use Direct Sequence Spread Spectrum (DSSS) transmission technology, ensuring an enhanced range of operation and better RFI immunity,” said Frank Beardsley, technical director at Rayco-Wylie.
Besides the pre-calibration and DSSS transceivers, the indicator’s main advantages and features include easy-to-read and waterproof display; transmission up to 0.5 mile without a repeater; internal antenna on display and sensor, which means low probability of damage and less downtime; battery life up to two years; and full FCC compliance.
