Abstract

A prolongation device for a shoring apparatus in mines, characterized by a beam terminated by complementary connecting elements, male and female, the female element having a flange provided with a transverse axis and perforated with windows behind this axis, while the The male element has the shape of a hook that can be hooked on the axis of the flange of another extension device, in such a way that the end of this hook is located in front of windows, which allows to tighten the extension device to the ceiling thanks to a key fitted in said windows and resting on a ramp at said end.
