For the adaptation logistics need to develop, has designed one kind of manual hydraulic pressure crane. The Machines of the Hydraulic Motive have many characteristics, such as the volume is small; the weight is light; the Construction is tightly; the exportation power is big; The work is steady; Can realizes to have no within the scope of big the class adjust speed; easily to carry the protection of the overloading; realizing straight line action is in brief. In the article introduced in detail manual hydraulic pressure crane various components and the hydraulic pressure design method, and has carried on the examination to each important part, as well as its structure, the principle of work and so on, this crane has the economy, practical, easy to pr
