Abstract
Improvements in the removable lifting frames, characterized in that the gantry is supported in an articulated manner by two movable end frames (1) on which it can be folded down at will, a portal that is entirely made from box girders (4), (5) ), between which the upper transverse beam (4) supports a lifting carriage (11) arranged externally cantilevered, while the lateral beams (5), which act as uprights, occupy a position inclined with respect to the vertical when the porch is ready to be used.
