The freight pneumatic elevators as a new form of transport

Abstract

This article addresses the problem of ensuring high reliability and safety performance of freight elevators. Rope elevator hoists exist more than one hundred years and have become very common, but it is very difficult to achieve their operational efficiency. The authors propose a solution to the problem - the introduction of a fundamentally new type of transport - pneumatic lifting, which capable provides high technical and economic performance. At the specialized enterprise Pnevmopod"yem a small-lot manufacture of new import-substituting equipment for hoisting in building sestablished. The authors present the advantages and the principle of operation of the developed pneumatic elevator. Essential advantage of this machine is the safe work which is incorporated in its design. Considerable attention is paid to the results of tests of cargo pneumatic elevator. The authors come to the conclusion that the design of a freight pneumatic elevator makes it possible to use it successfully for transporting cargo in buildings and structures for various purposes, to reduce capital investments in construction, installation and operating costs. The absence of foreign analogs will allow selling pneumatic lifts not only in Kazakhstan, but also in the countries of the former USSR.
