Skyjack SJ20 is a self-propelled aerial lift designed for indoor and outdoor access work. It is a compact electric scissor lift used for maintenance, installation, construction, and facility operations where elevated work platforms are required. The SJ20 typically features a narrow chassis, non-marking tires, and a working height suited to low- to mid-level access applications. Common equipment includes proportional controls, extendable platform options, and safety systems for operator use. Skyjack aerial lifts are known for simple mechanical design and service access. The SJ20 is used in warehouses, commercial buildings, industrial sites, and rental fleets.
