A forklift truck with reduced turning radius is equipped with: a frame (2); two front drive wheels (3a, 3b) that turn about a common axis of rotation (A) transversal to a longitudinal central plane (M) of the forklift truck (1) itself; a rear axle (14) supporting two back wheel mounting forks (10) which rotate about respective second axes (12) substantially parallel to the central plane (M) and mounting in turn two steerable back wheels (4a, 4b); a steering device (26) designed to coordinate the rotation of the mounting forks (10) about the respective second axes (12) in such a way that the centre of rotation (C) of the forklift truck (1) with the steering at full lock is positioned at the point where the first axis (A) intersects the central plane (M); and a rear counter-weight (35). The axle (14), the mounting forks (10) and the steering device (26) form a unit (33) which can be pre-assembled and which is supported directly by a back end (36) of the frame (2), which also directly supports the counterweight (35) in a position in which the unit (33) is located between the back end (36) and the counterweight (35) itself. The frame (2) has a rear opening (34) providing access to the steering device (26).
Cette invention se rapporte à un chariot élévateur avec rayon de rotation réduit, qui comprend: un châssis (2); deux roues motrices avant (3a, 3b) qui tournent autour d'un premier axe de rotation commun (A) transversal à un plan médian longitudinal (M) du chariot élévateur (1) lui-même; un essieu arrière (14) servant de support à deux fourches (10) portant des roues arrière, qui tournent autour de seconds axes respectifs (12) essentiellement parallèles au plan médian (M) et soutenant à leur tour deux roues arrière orientables (4a, 4b); un dispositif de direction (26) conçu pour coordonner la rotation des fourches de support (10) autour des deux seconds axes respectifs (12) pour que le centre de rotation (C) du chariot élévateur (1), lorsque le volant est tourné au maximum, se situe au point où le premier axe (A) coupe le plan médian (M); et un contrepoids arrière (35). L'essieu (14), les fourches de support (10) et le dispositif de direction (26) forment une unité (33) qui peut être préassemblée et qui est directement soutenue par une extrémité arrière (36) du châssis (2), qui soutient également directement le contrepoids (35) dans une position où l'unité (33) vient se placer entre l'extrémité arrière (36) et le contrepoids (35) lui-même. Le châssis (2) possède une ouverture arrière (34) permettant l'accès au dispositif de direction (26).
