Abstract

The invention relates to cranes, in particular to a crane hydraulic system and a working method. The hydraulic system comprises a hydraulic oil tank, a main pump assembly, a switch assembly, a rotarysystem used for driving a rotary mechanism, a main hoisting system used for driving a main hoisting winch, an auxiliary hoisting system used for driving an auxiliary hoisting winch, a luffing system used for driving a luffing winch and a cable stabilizing system used for driving a cable stabilizing winch, wherein the input end of the main pump assembly is connected with the hydraulic oil tank, andthe output end of the main pump assembly supplies oil to the luffing system, the main hoisting system, the auxiliary hoisting system, the rotary system and the cable stabilizing system through the switch assembly. According to the crane hydraulic system and the working method, the influence of impacting the crane hydraulic system when a load swings and shakes is reduced, the pressure of the cranehydraulic system is balanced, and the safety and stability of the crane hydraulic system are improved.

Description

technical field [0001] The invention relates to a crane, in particular to a crane hydraulic system and a working method. Background technique [0002] Marine cranes are a special type of cranes that perform transportation operations in the offshore environment. They are mainly used for important tasks such as transportation and transfer of cargo between ships, replenishment at sea, and launching and recycling of underwater operating equipment. Marine cranes are generally controlled by the crane hydraulic system. During the working process, the hull pitches, rolls and heaves with the waves. These movements will cause the load to sway and sway. The swaying and swaying of the load will form a huge impact on the hydraulic system, causing the hydraulic system of the crane to be unstable. [0003] The hydraulic system of the crane provides power and brakes to the main hoisting winch, auxiliary main hoisting winch, luffing winch and slewing platform. When the oil pressure suddenl...
