Title:
CONTROL DEVICE FOR BALANCING CARGO HANDLING EQUIPEMENT
Document Type and Number:
WIPO Patent Application WO/1991/017945
Kind Code:
A1
Abstract:
A control device for a balancing cargo handling equipment intended to accurately detect the weight of a work to be hung even if a drift is generated in an acceleration detector, and make the stabilized operation possible. Said control device is provided with an acceleration compensation computing part (23) that, when the respective absolute values (|Va| and |V|) of the fluctuation of the acceleration signal (Va) from an acceleration detector (8) and the fluctuation of the speed signal (V) from a speed detector (3) are smaller than the preset values (Ea and Ev) for a fixed time, outputs the difference between an averaging signal (VaPHI) obtained by averaging acceleration signals (Va) during that time and the acceleration signal (Va) to a command computing part (17) and a load memory computing part (22) as a compensation acceleration signal (Va').
