英文名称：Agricultural tractors — Test procedures — Part 2: Rear three-point linkage lifting capacity

发布日期：1993-08

标准范围

规定了确定后置三点悬挂系统提升能力的试验程序:a）液压升降机在下部悬挂点的整个运动范围内可施加的最大垂直力；b） 液压升降机可施加的最大垂直力，位于连接至三点悬挂机构的机架上挂接点后部610 mm处，贯穿其整个运动范围；c） （可选）提升系统在没有液压动力的情况下将负载保持在提升位置的能力。

Specifies test procedures for determining the lifting capacity of rear-mounted three-point linkage systems: a) the maximum vertical force which can be exerted by the hydraulic lift at the lower hitch points throughout their full range of movement; b) the maximum vertical force which can be exerted by the hydraulic lift, at a point 610 mm to the rear of the hitch points on a frame attached to the three-point linkage, throughout its full range of movement; c) optionally, the ability of the lifting system to maintain the load in the lifted position without hydraulic power.
