A single beam aerial work platform.

摘要

A single beam aerial work platform with a base structure (60), top structure (80), and at least three scissor mechanisms (14). The extending means (116) for raising the top structure (80) relative to the base structure (60) is attached between the first or lower scissor mechanism and the third or top scissor mechanism. The extending means (116) are attached by mounting means (100,108) at an offset to the pivot points and structural members of the scissor mechanisms (14). An additional stress reducing beam (90), attached parallel to one of the structural members of the middle scissors mechanism, reduces the horizontal bending stress in the structural members of the scissor mechanisms (14) and the connecting pin loading in the scissor mechanism pins. <IMAGE>
