摘要： A snowmobile jack is described herein that raises the rear of the snowmobile off of the ground when it is not in use. Manufacturers suggest that snowmobiles be raised when not in use, so that their tracks do not freeze to the ground. Manufacturers also recommend that snowmobiles be warmed up with their tracks elevated. This cuts down on general wear and tear of the tracks and supporting belts. The jack comprises a vertical lift bar slidable within a sleeve. The bar is raised by a foot pedal lever which acts on the lower end of the bar and is latched in the raised position. The bar carries a transverse rod adjustable in height relative thereto with hooks for engaging the rear bumper of the snowmobile.
摘要翻译：本文描述了一种雪地车千斤顶，其在不使用时将雪地车的后部从地面提升。制造商建议在不使用雪地车时，不要将雪轨冻结在地面上。制造商还建议，雪地摩托车的高架轨迹会升温。这减少了轨道和支撑带的一般磨损和撕裂。千斤顶包括可在套筒内滑动的垂直提升杆。该杆由一个作用在杆下端并被锁定在升高位置的脚踏杠杆升高。该杆带有相对于其高度可调节的横杆，其具有用于接合雪地车的后保险杠的钩。
