专利汇可以提供Folding system for multi-sectional implement专利检索，专利查询，专利分析的服务。并且A method and means of folding a multi-section field machine, such as agricultural implements, which require a reduction in width for or during transportion. A series of strategically placed hydraulic rams serve to fold sections of the implement, in stages, to folded positions of at least 90*.，下面是Folding system for multi-sectional implement专利的具体信息内容。
1. In a multi-sectioned field machine having an inner, towing section and a plurality of outer wing sections pivotally hinged to one another And to at least one side of the towing section, means for folding said wing sections relative to one another and to said towing section between unfolded operating and folded towing positions, each of said folds being in excess of 90*, said folding means for each said section comprising; interconnecting adjacent sections by a hydraulic ram; pivotally connecting the piston rod end of the ram to one section; a lug on the adjacent section for securing the body end of the ram thereto; the length of the ram between extended and retracted positions being great enough to fold the adjacent section beyond 90*; and the height of said ram body lug being sufficient to provide that, between the folded and unfolded positions of said sections, the piston rod end of the ram does not reach an over centre mark with regard to the body end of the ram.
2. In a multi-sectioned field machine having an inner, towing section and a plurality of outer wing sections pivotally hinged to one another and to at least one side of the towing section, a method of determining the location of hydraulic rams interconnecting said sections for folding said wing sections relative to one another between operating and towing positions through angles in excess of 90*, said method comprising: a. selecting an angle of fold in excess of 90* for each section between its unfolded operating position and its folded transport position with respect to an adjacent section; b. projecting the available ram travel across the selected angle of fold; c. securing the piston end of the ram to one section; d. positioning a lug on the other, adjacent section and securing the body of the ram thereto and e. selecting the height for said ram body lug to provide that, between the folded and unfolded positions of said sections, the piston rod end of the ram does not reach an over centre mark with regard to the body end of the ram.
