Lift with Confidence, Lift with Power Our long ram hydraulic jack effortlessly handles weights up to 3 tons, making them perfect for cranes in various fields, including professional machinery, maintenance, and home use. The hoist jack transforms your existing crane into a convenient, efficient, and safe lifting solution. With a lifting range of 26.2"-46" (665-1170 mm) and a lifting stroke of 19.9 inches (505 mm), our engine hoist jack allows you to handle large objects with ease and speed. The 3-ton engine hoist cylinder is crafted from durable #45 steel. The large 28mm hydraulic cylinder reduces the required oil pressure for load movement. The Y-ring plunger design ensures a stable and safe lifting process, preventing slow descents or oil drift. Our hydraulic ram pump allows you to apply minimal muscle force for lifting heavy objects. The oil return valve should be gradually loosened when retracting the piston rod to prevent rapid descent. This clevis base long ram hydraulic jack can be easily installed on most cranes, making it suitable for off-road backup, construction, industrial, mining equipment, and various lifting scenarios.
