Articulated work platform with scissors motion

摘要

An improved work platform suitable for mounting on a vehicle mounted telescoping boom. The work platform includes a fixed platform section mounted on the tip of the boom in conjunction with a leveling mechanism. Two movable side platform sections are pivotally fastened at one of their ends to the fixed platform section for independent movement on either side of a centerline. The side platform sections may be moved apart in a scissors-like motion so that the platform may be maneuvered to straddle the object being worked on. Bumpers and troughs are provided along the inner edge of the side platform sections to protect the object being worked on and to prevent articles from rolling off the platform. When the side panel sections are moved into abutment to use the platform as a conventional unitary platform, a hinged flap on one of the side platform sections covers the abutting edges of the side platform sections, the bumpers and the troughs. A pin on one side platform section is extendable to engage a loop on the other side platform section to prevent differential deflection of the outer ends of the side platform sections. A proximity sensor is provided to prevent the work platform from striking and damaging the object being worked on.
