The Strongarm 780SHD is a super heavy duty air hydraulic truck jack with two lifting stages: 80 T and 50 T. Intended applications include heavy trucking, agriculture, construction, military equipment and aircraft. Its 138cm (54") handle offers three locking positions to help position the jack where access is restricted. Load control features include a descent metering valve and overload protection, while air-assisted lowering helps speed ram retraction. Two extensions and a saddle adaptor are included. Catalogue SKU: SUW-030477.

• Lifting dimensions: the 80 T first stage reaches 340 mm (13.39") with 110 mm (4.33") of lift; the 50 T second stage reaches 440 mm (17.32") with 210 mm (8.27") of lift. Minimum height is 230 mm (9.06").
• Required working air pressure for the 80 Ton stage is 0.8–1.2 Mpa (116–174 PSI).
• The piston-head seal uses an industrial-derived design for sealing at both low and high pressures under severe loads. Double-polished, chromed pistons support tighter tolerances to reduce oil bypass and ram scoring. A one-piece base adds strength and load stability.
• An integral descent metering valve controls load lowering. Air assistance accelerates ram retraction, and a built-in overload safety valve protects the jack against damage from excessive loads.
• Supplied accessories comprise two extensions, measuring 75mm and 45mm, plus a saddle adaptor. The long handle locks into three positions.
• Testing includes temperatures of -25˚C and +45˚C, along with off-centre loading. The jack weighs 105 kg (233 lb); its shipping mass is 109 kg (240 lb).
