The Skyjack SJIII 3219 is a narrow electric scissor lift in the same heavily hired UK indoor access class as the Genie GS-1932 and JLG 1930ES. Skyjack markets the SJIII range on simplified hydraulics and a smaller parts count than some competitors, which UK hire companies value for keeping fleet maintenance costs down. It is a common sight on retail fit-out and warehouse maintenance jobs where a machine needs to pass through a standard doorway.
