S), to determine the twisted cylinder Xiazuo contacts C position, the boom four component system design and calculation of the overall layout of the maximum working load of tanks of this design method is more practical character hydraulic crane requirements and facilitate the selection of the best tank size and type. (2) examples of this design method has been verified, you can quickly and easily be overweight arm system design. Trial and error than the mapping method and the cylinder mounting dimensions as the basis of the design more reasonable,<a href="http://www.toryburchrevaflats.org" target="_blank" class="postlink">tory burch</a>, convenient and with high precision. (3) can be seen from the design example, the maximum working load cylinder r, ... than from the weight of the hydraulic crane Ⅵ, large 4 times, so can not be used as a selection from the weight of tanks and bar design basis.
