A hand trolley including an open frame (1) for securely holding a load (7), a handle means (8) for operating and manoeuvring said trolley, and wheels (4) fitted to either side of frame (1). The centre of mass of load (7) when load (7) is securely held in frame (1) is substantially at or near the axis of rotation of frame (1) about wheels (4). Each wheel (4) can be replaced by a set of two or three smaller wheels mounted on a common carrier, with the carrier having an axis of rotation about axle (5) to allow the trolley more stability when negotiating uneven terrain. The trolley can manoeuvre high mass loads, such as pallets of building or paving bricks, sleepers, and rocks over the rough terrain of a construction site.

L'invention concerne un chariot de manutention à châssis ouvert (1) permettant d'assurer le maintien fiable d'une charge (7), qui comporte des poignées (8) de manipulation et de manoeuvre, et des roues (4) de part et d'autre du châssis (1). Le centre de la masse de la charge (7), lorsque celle-ci (7) est maintenue de manière fiable sur le châssis (1), est sensiblement au niveau de l'axe de rotation du châssis (1) par rapport aux roues (4), ou à proximité de cet axe. Chaque roue (4) peut être remplacée par une série de deux ou trois roues plus petites montées sur un support commun, ledit support ayant un axe de rotation autour de l'axe (5) qui confère une plus grande stabilité au chariot en cas d'inégalité de terrain. Le chariot peut transporter des charges à masse élevée, du type palettes de briques à bâtir ou à paver, traverses de chemin de fer, ou roches sur le terrain accidenté d'un chantier de construction.
