Abstract:

A device for automatic equilibration of the hydraulic jib crane consisting of mobile counterbalance, subject to the change of load, run by power hydrocylinder connected with cylinder-transducers, placed on the operating devices that determine load and retaining moments. To raise safety measures of the cranes operation, a distributing slide-valve is installed in the artery connecting transducers with power hydrocylinder of counterbalance. This distributing slide-valve guarantees the feedback control of counterbalance blocking the operating mechanisms of the crane in time of its unbalanced state. Author
