Northern Hydraulics supplies Enerpac PR-Series, pneumatic Pow'r-Riser lifting jacks for air-powered lifting where a shop air line replaces a manual or electric pump. Enerpac, the Milwaukee high-pressure hydraulic manufacturer founded in 1910, builds this category around self-contained air-over-hydraulic lifting so crews can raise heavy loads with plant compressed air instead of a separate power unit. We carry 10 PR-Series jacks and related lifting equipment, and we cross-reference discontinued part numbers against current Enerpac production. If you are matching an obsolete tag or pairing a jack to an existing air supply, request a cross-reference quote.
Sizing starts with rated capacity in tons, lift height (stroke), and how the load is supported. A pneumatic Pow'r-Riser jack runs off plant air, which keeps it useful where electric power is restricted; for purely hydraulic lifting you compare it against pump-and-cylinder setups. The related Enerpac families on this site cover the rest of a lifting rig: browse Hydraulic Jacks for mechanical and hydraulic jack options, Hydraulic Cylinders for single- and double-acting RC- and RR-series rams when you need separate lifting points, and Hydraulic Pumps for P-series hand, ZU-series electric, or PA-series air-driven power. Round out the system with Hydraulic Hoses rated for the working pressure and the broader Hydraulic Tools and Enerpac Hydraulic Tools ranges. Not sure which jack matches your load and air pressure? Send the existing part number and we will confirm fit.
Lifting jacks and the air-over-hydraulic equipment around them turn over part numbers as Enerpac revises its line, so the tag on an older Pow'r-Riser jack may no longer match current production. We cross-reference discontinued Enerpac numbers to equivalent current-production replacements and pull from the wider Enerpac catalog, including RC- and RR-series cylinders and P-, ZU-, and PA-series pumps, when a like-for-like jack is no longer offered. Enerpac's own line moves the same way: the XC-series cordless pumps were discontinued in favor of the current SC-series. Send your capacity, stroke, and the number stamped on the unit and we will identify the equivalent part. Request an Enerpac cross-reference quote.
