SOUTHERN HYDRAULICS

Southern Hydraulics telescopic cylinders are available in 2-stage and 3-stage configurations. Bore diameters range from 3 inches to 5 inches, and stroke lengths range from 40 3/8 inches to 89 13/16 inches. All models are single-acting and feature a 1/2 in-14 NPT port. They are constructed with welded steel bodies. Specific part numbers include 210570 (3 in bore, 40 3/8 in stroke, 2-stage), 210573 (4 in bore, 47 1/4 in stroke, 2-stage), 210515 (4 in bore, 57 7/8 in stroke, 2-stage), 210576 (4 in bore, 73 7/8 in stroke, 3-stage), 210577 (4 in bore, 89 13/16 in stroke, 3-stage), 210579 (5 in bore, 69 1/8 in stroke, 3-stage), and 210488 (5 in bore, 89 13/16 in stroke, 3-stage).

Southern Hydraulics telescopic cylinders are commonly used in dump trucks, trailers, and other heavy-duty lifting and dumping applications. Their single-acting design and telescopic construction make them suitable for situations where a long extension stroke is needed from a compact retracted length. Typical uses include raising dump bodies, operating trailer lifts, and in various mobile hydraulic systems where space is limited. They can also be found in industrial lifting equipment and maintenance applications requiring linear force. The welded construction and standard NPT ports allow for integration into existing hydraulic circuits.

Selection depends on required stroke, bore diameter, and mounting constraints. Determine the necessary extension length and the available space when retracted. The bore diameter affects the force output at a given pressure. Southern Hydraulics offers 2-stage and 3-stage models; 3-stage cylinders provide longer strokes from a shorter retracted length. All models have 1/2 in-14 NPT ports, so ensure your hydraulic system uses compatible fittings. Consider the load and duty cycle to choose the appropriate bore size. For assistance, consult the specification data for each part number, such as 210577 or 210579, and match to your system's pressure and flow capabilities.

The Southern Hydraulics telescopic cylinders listed in 3G Electric's catalog are single-acting. This means hydraulic pressure is applied to extend the cylinder, and retraction is achieved by an external force, such as gravity or a return spring, depending on the application. Single-acting cylinders are common in dump truck and trailer applications where the weight of the load or the equipment itself provides the retraction force. They require only one hydraulic line, simplifying plumbing. The port size for all these models is 1/2 in-14 NPT.

The number of stages refers to the number of telescoping sections. A 2-stage cylinder has two sections, while a 3-stage cylinder has three. 3-stage cylinders can achieve a longer overall stroke from a given retracted length compared to 2-stage models. For example, part 210577 is a 3-stage cylinder with a 4-inch bore and 89 13/16-inch stroke, while part 210515 is a 2-stage cylinder with a 4-inch bore and 57 7/8-inch stroke. The choice depends on the required stroke and the available space for the retracted cylinder. Both types are single-acting and share the same port size.
