The invention relates to a ship crane remote hydraulic control system. The system comprises a motor, the output terminal of the motor is connected to an oil pump, the output end of the oil pump is connected to a proportional multi-way valve through an electromagnetic reversing valve, the output terminals of the proportional multi-way valve are connected to a lifting device, a luffing oil cylinder, a telescopic oil cylinder, and a slewer; and the proportional multi-way valve is connected to a remote hydraulic control handle through a hydraulic soft pipe. The ship crane remote hydraulic control system has a compact and reasonable structure, and remotely controls the crane's motions through combining a remote hydraulic control handle and a proportional multi-way valve. The remote hydraulic control handle has a small volume, and does not occupy much space; furthermore, the operation of the handle is convenient, the control pressure of the remote control handle is low, and thus the handle is safer.
Description
technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a remote hydraulic control system for a marine crane. Background technique [0002] In the prior art, in marine hydraulic cranes, each movement of the crane is directly operated and controlled by a mechanical handle on a multi-way valve. Although the operation is simple and convenient, the cost is low. However, due to the large volume of the multi-way valve, it is not suitable to be installed in the driver's cab. For some cranes with a driver's cab, this operation method cannot fail to meet the use requirements. Affect the normal work of the hydraulic crane. Contents of the invention [0003] Aiming at the above-mentioned shortcomings in the existing production technology, the applicant provides a remote hydraulic control system for a marine crane with a reasonable structure, so that it is easy to operate, and the remote control handle is used for high safety and goo...
