Skyjack Boom Lift – articulating and telescopic boom lifts from the Canadian maker in Guelph: SJ12 to SJ86 T, operating weights from 782 to 16,965 kg
Skyjack is headquartered in Guelph, in the Canadian province of Ontario, and belongs to the industrial group Linamar. This page gathers the articulating and telescopic boom lifts of the SJ range, from the small SJ12 to the large SJ82 T, SJ85 AJ and SJ86 T. On Skyjack machines the number in the type gives roughly the working height in feet, so the SJ46 reaches about 46 feet of working height; the T suffix denotes a telescopic boom, AJ an articulating jib.

The register lists here 13 versions with operating weights of 782 to 16,965 kg, platform capacities of 225 to 227 kg and platform widths from 770 mm.
Articulating and telescopic boom lifts open up working heights that scaffolding or scissor lifts cannot reach, or only with great effort, for instance over obstacles, at facades or under building roofs; alongside JLG and Genie, Skyjack is one of the big three brands in this segment and is widely used on construction sites and in industry worldwide through rental fleets.
When buying used, what counts is the function of the hydraulic cylinders in the individual boom sections, the condition of the overload protection and the emergency lowering systems, the tyres and drive system, the electronics of the platform controls, and on electrically driven variants the condition of the batteries; wear parts and control electronics run through the Skyjack distribution network and its affiliated rental companies.
