Reducing maintenance downtime with a patented by-pass mechanism that prevents internal hydraulic damage, this 3-ton crane jack supports lifting heights from 19-7/8 to 35-1/4" (504.8 to 895.4 mm). It is constructed from hard-cast steel with heat-treated stress areas and a 5-1/8 x 4-1/2" (130.2 × 114.3 mm) base for stability. Additionally, machined and polished cylinders with die-cut threads provide a leak-free seal during operation.
