ABSTRACT:
An elevator, especially an oblique elevator, has a plurality of telescopic sections, along which a load container is movable. The telescoping of the sections takes place in such a manner that all the telescopic sections move simultaneously in relation to one another, or in such a manner that, as a given telescopic section extends, it takes with it all those arranged after it, as a "pack". For the purpose of locking in any desired position of extension a locking/unlocking device is provided between each pair of adjacent telescopic sections. This locking is effected by the actuation of a draw cable attached to the lowermost telescopic section, the draw cable acting upon an actuating cable which effects the locking or unlocking. The actuating cable runs in tackle block manner around two cable guides, and is shortened or lengthened by the variation of spacing of two cable guides.
