ABSTRACT:
A portable personnel platform lift is provided, having a base mast or section and a plurality of extendible, nesting masts or sections with a personnel platform on the upper section. The extendible sections are constructed with nesting side rails which are identical in size and shape. This reduces the inventory of materials required and also facilitates fabrication of the components of the lift. The base and extendible sections have adjustable greaseless guide blocks to eliminate periodic lubrication and dirty rails. The plaform and the extendible sections also are designed to enable a worker to enter the platform from the floor without a ladder when the platform is in the lowest position.
