Abstract: A lifting device for lifting a load positioned on a platform in which a hollow protective framework has a coupling at its upper end and a slidable lifting element is mounted at the lower end of the framework. The framework is formed by a rigid assembly of bars and supporting walls and the framework includes tubular supports which slidably receive support members of the lifting element. The lifting element is slidably moved to a retracted position and the framework is lowered onto the load whereafter the lifting element is slidably displaced to an inserted position within the framework where the lifting element now supports the platform from below so that when the framework is lifted, the lifting element will lift the load therewith.
