An attachment for industrial trucks, especially lift trucks, is designed as a multi-articulated lever mechanism (11), preferably as a three-hinge arm. This is articulated to a support plate (1), which can be locked and/or fixed in a bracket of the industrial truck. The lever arms (5, 6, 7) of the lever mechanism (11) are rotatable in relation to one another in articulated axles (3, 8, 10), and can be driven, individually and/or in a simultaneous movement, at least in the horizontal direction by mechanical, hydraulic and/or electrical devices. A load pickup device (12), which can be used preferably as a pivoting retractable fork, is arranged at the last, freely hanging lever arm (7). At least one of the lever arms (5 or 6 or 7) is adjustable in height along its articulated axle (3 or 8 or 10). The load pickup device (12) can be moved by translatory and/or rotary movement, in a time- and/or movement-optimized manner, to any point in the room, and the need for self-contained drive unit of the vehicle for the attachment is eliminated. Industrial trucks of the simplest design can be rapidly and inexpensively retrofitted with the attachment, and the utility value of the vehicle can be increased.

Abstract

An attachment for industrial trucks, especially lift trucks, is designed as a multi-articulated lever mechanism (11), preferably as a three-hinge arm. This is articulated to a support plate (1), which can be locked and/or fixed in a bracket of the industrial truck. The lever arms (5, 6, 7) of the lever mechanism (11) are rotatable in relation to one another in articulated axles (3, 8, 10), and can be driven, individually and/or in a simultaneous movement, at least in the horizontal direction by mechanical, hydraulic and/or electrical devices. A load pickup device (12), which can be used preferably as a pivoting retractable fork, is arranged at the last, freely hanging lever arm (7). At least one of the lever arms (5 or 6 or 7) is adjustable in height along its articulated axle (3 or 8 or 10). The load pickup device (12) can be moved by translatory and/or rotary movement, in a time- and/or movement-optimized manner, to any point in the room, and the need for self-contained drive unit of the vehicle for the attachment is eliminated. Industrial trucks of the simplest design can be rapidly and inexpensively retrofitted with the attachment, and the utility value of the vehicle can be increased.
