SYSTEM FOR CHECKING LOAD STABILITY OF MOBILE LOAD-LIFTING MACHINE Russian patent published in 2006 - IPC B66C23/90 G01M1/12 

FIELD: mechanical engineering; load-lifting machinery; safeguards.

SUBSTANCE: strain-gauge transducers are installed on outriggers. Analog-digital converter is connected to outputs of strain-gauge transducers. On-board microprocessor is installed for processing data array formed by analog digital converter, control of hydraulic cylinders of support circuit by hydraulic distributor and putting out required information to operator's display. Moreover, on-board microprocessor is furnished with relay module, and mathematical model of load-lifting machine made with possibility of changing, depending on type of load-lifting machine used, is entered into its memory. Additionally hydraulic distributor is connected in parallel with said hydraulic distributor coupled through system of controllers with relay module of on-board microprocessor and designed for re-distribution of liquid from piston spaces of hydraulic cylinders in case of danger of turnover of load-lifting machine.

EFFECT: increased capacity of machine, improved safety at load-handling operations.
