Single Acting Hydraulic Power Units

A single-acting hydraulic power unit is designed to provide hydraulic pressure to extend a cylinder in one direction. It typically supports “power up,” meaning it can push the cylinder outward when activated by pressurizing hydraulic fluid. This design is common in applications like dump trailers and wheelchair lifts, where controlled retraction is not critical.

You would typically choose a single-acting hydraulic power pack over a double-acting one in situations where you need hydraulic power for extending a cylinder in one direction only and controlled retraction isn’t important. Single-acting units are often used when simplicity, cost-effectiveness, and the absence of a power-down function are acceptable for the application. Read more...
