Described herein is a portable, vertically adjustable, scaffold. This scaffold comprises a base, a telescoping mast hingeably attached thereto and a platform. The telescoping mast is raised by a hydraulic hoist and the mast is rotated about its lower end with a hydraulic hoist. As the telescoping mast is raised, a cable secured to the mast raises the platform assembly along the mast. Outriggers are provided to add stability to the scaffold.
