METHOD OF AND DEVICE FOR SIMULATION OF LOADS FOR LOAD-LIFTING SETS Russian patent published in 2006 - IPC B66C23/90 

Abstract RU 2274599 C2

FIELD: mechanical engineering; tower cranes.

SUBSTANCE: invention relates to materials handling facilities and it can be used particular to adjust overload safeguards of tower cranes. Suspended dynamometer with direct of remote control is used when accomplishing the method and implementing the device. Dynamometer is installed between load hook and point of fastening, and load moment is controlled after setting lifting mechanism in adjustment position. For this purpose preset value limiting load torque of electric motor which control operation in direction of lifting is supplied by sending order to said motor and reading values of stretching forces put out by suspended dynamometer.

EFFECT: reduced duration and cost of adjustment of overload safeguards.
