FIELD: shipboard crane hydraulic systems.
SUBSTANCE: proposed hydraulic system includes air-loaded hydraulic accumulator hydraulically connected with hydraulic cylinders of main section of boom and its gooseneck forming drive for changing boom outreach, hydraulic motor of crane turn drive, hydraulic motor of cargo winch drive which is connected with cargo drum and hydraulic motor of this drive which is connected with tensioning drum included in cargo winch equipment and crane trolley stopper drive; crane trolley moves in mode of abeam transfer of cargoes from one ship to another and gets locked on boom end by said stopper. System is provided with flow divider which consists of two hydraulic motors; hydraulic motors of cargo winch are connected through this flow divider to said air-loaded hydraulic accumulator; system is also provided with supercharged tank connected with constant-delivery pump and with cargo winch hydraulic motors.
EFFECT: enhanced reliability.
