A lifting apparatus (10) for lifting an endless conveyor belt (11) supported on a support frame structure (15) including two spaced apart frame members (33). The lifting apparatus (10) comprises a lower beam member (57) for extending between and resting on the two frame members (33) and an upper beam member (53) for engaging a section of the conveyor belt (11) to be lifted. A jack means (59) is operable between the two beam members (53, 57) for selectively moving the two members towards and away from each other between extended and contracted conditions. The jack means (59) comprises two telescopic rams (61) disposed to extend outwardly of the two beam members (53, 57) when in the contracted condition. This allows the two beam members (53, 57) to assume a compact arrangement when in the, contracted condition.
Appareil de levage (10) destiné à lever la bande sans fin (11) d'un convoyeur, porté sur une structure de cadre de support (15) comprenant deux éléments de cadre (33) espacés. L'appareil de levage (10) comprend une barre inférieure (57) s'étendant entre les deux supports (33) de cadre et reposant sur ceux-ci, ainsi qu'une barre supérieure (53) venant au contact d'une partie de la bande (11) du convoyeur à soulever. Un vérin (59) peut être actionné entre les deux barres (53, 57) afin de rapprocher et d'éloigner sélectivement lesdites barres dans des positions distantes et rapprochées. Le vérin (59) comprend deux pistons télescopiques (61) disposés de manière à s'étendre à l'extérieur des deux barres (53, 57) lorsqu'elles sont en position rapprochée. Ceci permet aux deux barres (53, 57) de prendre une configuration compacte lorsqu'elles sont rapprochées.
