A trailer jack includes a vertically oriented vertically extendable jack and a mounting flange on the jack. The mounting flange includes three bolt patterns. Each of the three bolt patterns includes a front slot and two rear slots defined through the mounting flange. Each slot includes a longitudinal axis. The longitudinal axes of the slots of any single bolt pattern intersect at a bolt pattern axis closer to the front slot than to the rear slot. Longitudinal axes of the front slots intersect at the central axis. The central axis is offset from each of the three bolt pattern axes. The rear slot of any of the bolt patterns is non-radial with respect to the central axis. The front groove of any of the bolt patterns is radial with respect to the central axis.
一种拖车千斤顶包括竖直定向的可竖直延伸的千斤顶和位于所述千斤顶上的安装凸缘。安装凸缘包括三个螺栓模式。三个螺栓模式中的每个包括穿过安装凸缘限定的前槽和两个后槽。每个槽包括纵向轴线。任何单个螺栓模式的槽的纵向轴线在更靠近前槽而不是后槽的螺栓模式轴线处相交。前槽的纵向轴线在中心轴线处相交。中心轴线从三个螺栓模式轴线中的每个偏移。任何所述螺栓模式的后槽相对于中心轴线是非径向的。任何所述螺栓模式的前槽都相对于中心轴线是径向的。
