Born of same parents of change function nonlinearity input mechanism formula hoist has

The utility model provides a born of same parents of change function nonlinearity input mechanism formula hoist has, includes jack -up davit telescopic machanism, becomes born of the same parents control mechanism and davit guiding mechanism. Jack -up davit telescopic machanism comprises jib loading boom, davit, balancing piece and jack -up loading and unloading pincers, can make the hoist accomplish spaces such as the snatching of container, handling and discharge and operate, become born of the same parents control mechanism and davit guiding mechanism and be formed by connecting by the connecting rod, accomplish the motion adjustment to the davit through the motion synthesis of connecting rod. The utility model discloses a mechanism's formula is connected, makes the hoist have compact structure, reliability height, simultaneously the utility model has the advantages of it is big to control simple advantage, working space, can overcome effectively that the hydraulic crane hydraulic component machining precision expects much, maintenance is with high costs, reliable degree is low, leaky wet goods shortcoming.
