FIELD: shipboard load handling devices. ^ SUBSTANCE: proposed shipboard crane has housing 1 hinge connected with loading boom consisting of main section 6 connected by hydraulic cylinder with housing, fly jib 7 hinge connected by hydraulic cylinder with main section on end of which rotary end 12 rotary case 10 with sheaves are installed on one axle. Said sheaves are used to pass load and carrying cables to end. Carrying cable is made for passing under rollers of load car and reeving in receiving sheave. Two-drum load winch 3 with load and carrying cables and self-contained drive hydraulic motors and follow-up winch 5 are mounted on main section. Load hanger for lifting and lowering of load is connected by load cable with rotary end 12 for removal. Carrying cable can be disconnected from end and fastened, after reeving on receiving sheave, on load car provided with winch and made for connection of load cable. ^ EFFECT: improved reliability and safety of load handling at rolling. ^ 2 dwg |
