Multipurpose load lifting work platform or/and composite bridge structure

Abstract

The present invention discloses a multi-purpose load lifting work platform or/and composite bridge structure, comprising a framework, at least one work platform, a drive mechanism, and an electrical control devices. One end of the pole-shaped structure is connected with the framework in a movable manner, and the other end of the pole-shaped structure is connected with the work platform in a movable manner, the work platform can run with the pole-shaped structure together. The work platform can run in a curve track relative to the framework by power, and can stop at any position in running track. This invention can provide two platforms working coordinately or a single platform working independently. The working area of the two platforms greatly exceeds that of the existing common equipment with a single platform. It can load bulky objects without sway, and can also be used as composite or assembly bridge structure.
