<p>PURPOSE:To efficiently convey a material by hooking one end of a wire rope suspended on a pulley above a bogie vertically lifted or lowered along a multi- story building on the bogie, hooking the other end on a winding device, and fitting a braking device to the bogie. CONSTITUTION:A rigid guide rail R is vertically fitted to a multi-story building such as a steel tower T. A cargo holding section 6 is provided on a bogie device 2 coupled with the guide rail R and moved vertically, and it holds a material L to be conveyed and conveys it to the desired position. A wire rope 5 is suspended on a pulley device 3 provided above the lift range of the bogie device 2, one end of the rope 5 is hooked on the bogie device 2, the other end is hooked on a driving device 4, the rope 5 is wound or unwound to convey the material L. Rollers 9 of the bogie device 2 are normally rolled in the guide rail R, when the bogie device 2 starts to be quickly lowered in an accident, a brake section 7 strongly presses the guide rail R via a link mechanism to apply a brake. the desired work at a high position is easily and efficiently performed.</p> |
