Abstract (en)
[origin: US4677444A] The invention relates to a device for raising a mast from a ground lowered position to a raised position at which it is supported on a base. The lower end of the mast is supported on the base by a connecting link comprising an upper fork and a lower fork joined by a link. The lower fork is fixed relative to the mast, but can be articulated with the mast about a mast-raising axis. The upper fork of the connecting link is connected to the lower part of an arm of a lever along a folding axis which axis is orthogonal to the mast-raising axis.
