The Big Joe J1 Task Support Vehicle is a self-propelled, battery-powered elevating work platform designed for indoor use on level surfaces. It is intended for general maintenance work and efficient material handling in warehouses and storerooms, allowing a single operator to perform tasks such as stock selection, driving, and stock replacement at various heights.

Function Description:

The J1 vehicle lifts and transports an operator and loads up to 1,000 pounds (including the load shelf and occupant). It features an AC drive motor for forward and reverse propulsion, with speed restrictions when the platform is raised. On-demand power steering provides high maneuverability and quiet operation. The operator platform includes a "deadman" footswitch that must be engaged for the vehicle to operate. Control arms are used for vehicle operation and operator safety. A pick tray is provided for placing and transporting merchandise, and a folding rear tray can transport up to a 200-pound load.
