The wheel-type hoist crane is an widespread utilization important hoisting equipment in each kind of engineering construction. It is playing the vital role in the realization engineering construction modernization process which cannot be substituted. It is used to carry on lifts heavy objects, work and so on transportation, load and unload or install mechanical devices, obtains the widespread utilization as the main construction machinery in the industry and the civil construction. This article has given 55 ton hydraulic pressure wheel-type hoist crane overall and the hydraulic system detailed design process and the result. This article has given the overall of the 55 ton hydraulic pressure wheel-type hoist crane and the detailed design process and result of the hydraulic system. First, in the stage of system design, the projects of the lifts bodies, the rotation bodies, the amplitude bodies, the expansion and contraction bodies, the leg retraction jack and so on are designed, the anization plan are choosed. Among them, the lifts bodies is designed detailed, including choosing puting each part’s parameter and choosing standard parts .The hydraulic system design includes all hydraulic system return routes including the design and the choice of anization bodies, and carries on the parameter design to each hydraulic unit, chooses the appropriate hydraulic pressure to make the hydraulic system satisfy the work requirement and the intensity.
