摘要

Extendable lifting device for lifting and/or supporting loads at a certain height, inside a space at least partially limited in height by a supporting surface, comprising a telescopic column, a platform elevator, movable axially along the telescopic column, and a traction mechanism, characterized in that the traction mechanism is arranged in such a way that it allows to apply, simultaneously, a force f1 to the platform lifts to lift a load, and a force f2 to a plate, arranged at the top of the telescopic column, to block the elevator against the supporting surface, and because the forces f1 and f2 are directly proportional.
