Abstract
Improved mechanical lifting apparatus, of the kind comprising a frame with two vertical uprights from a platform and with guides for sliding a lift chair, essentially characterized by the fact of carrying out all the work of ascending and descending this lift chair, by means of belts and cables, without intervention of gears, comprising in the lower area of the uprights an electric motor that transmits its effort to a pulley of greater diameter than that of that, and that thus establishes a first speed reduction, this being receiving pulley mounted directly on the shaft of a horizontal drum, tractor of the working cable, this drum being of smaller diameter than the pulley to cause a new speed reduction, transmitting by means of coiled cable, its rotary movement to a differential in the that, two or more double pulleys communicate a new speed reduction before acting the tractor cables in the s illa elevator, depending on the effort obtained from the number of pulleys used which allows it to be a minimum using cables of a reduced diameter, a circumstance that results in also have a smaller diameter in the drum and therefore a greater facility to obtain a new speed reduction, which allows lifting with the speed necessary to lift the weight without the use of any gear.
