Lifting frame for ceiling panel installation - has motor driven double scissor linkages with telescopic upper links carrying travel limiting switches

摘要

The lifting frame to enable ceiling panels to be installed, can be used for renovation work and can be operated by one man. An upper platform (14) is attached by double scissor linkages (12) to a wheeled base. The linkages are extended by a nut and screw (78,80) attached to the lower part with the screw (78) driven by a motor (74). The arms of the upper part include telescopic portions (94) forming an angle control. These telescopic parts are spring loaded, and switches can be included to stop the driving motor when the linkage is fully extended. A horizontal auxiliary platform (88) can be mounted on the lower part and auxiliary frames (100,104) on the upper platform can include extending frames (100).
