The invention concerns a self-propelled transport and handling device (1) for picking up and towing a load (2), such as a skip (3), comprising a rigid structure (4) provided with running (9) or sliding means at least in its rear part (8), opposite catching means (6) provided on its front part (5) and capable of co-operating with towing means (7) associated with said device (1), which comprises at least a wheel (10) both steering and driving. Said device is characterized in that it comprises a hook (12) capable of co-operating with said catching means (6) with matching shape and lateral grip means (13) designed to be urged to be fastened, from the lateral sides of the load (2) to prevent the self-propelled device (1) from rotating relative to said load (2) about a vertical pivoting axis passing substantially through the hook (12).
Self-propelled transport and handling device (1) for picking up and towing a load (2), such as a loading platform, a skip (3) or the like, including a rigid structure (4) provided with rolling (9) or sliding means at least in its rear portion (8), opposite catching means (6) provided for on its front portion (5) and capable of co-operating with towing means (7) associated with said device (1), which comprises at least a steering and driving wheel (10), characterized in that the towing means (7) consist of means designed capable of making integral, without freedom of movement relative to each other, said device (1) with the load to be towed (2) and include, on the one hand, a hook (12) capable of co-operating with said catching means (6) with matching shape and, on the other hand, lateral gripping means (13) designed capable of being fastened, from the lateral sides, at the level of these catching means (6) of the load (2), in order to prevent the self-propelled device (1) from rotating relative to this load (2) about a vertical pivoting axis passing substantially through the hook (12).
Self-propelled device (1) according to any of the preceding claims, characterized in that it includes one single steering and driving wheel (10) pivotally mounted about a vertical pivoting axis (15) passing substantially at the level of its median plane, with this wheel (10) being associated steering control means (17) that are namely designed so as to subject it to a rotation of more or less 90° with respect to its reference position (18), on the axis (19) of the load (2).
Self-propelled device (1) according to any of the preceding claims, characterized in that it includes a thermal or electric engine for ensuring the operation of a hydraulic central unit for feeding hydraulic jacks corresponding to lifting means (11) and/or gripping means (13) associated with the towing means (7), as well as a hydraulic engine associated with the steering and driving wheel or wheels (10).
Self-propelled device (1) according to any of the preceding claims, characterized in that it includes control means (14) provided for at the level of its structure, in the form of a driver's platform (15) designed so as to receive an operator.
Self-propelled device (1) according to any of the preceding claims, characterized in that it includes auxiliary rolling means (26) designed capable of providing it with the necessary stability to allow it to move after it has been dissociated from a load (2), such auxiliary rolling means (26) being designed retractile, through lifting means (30), so as to allow releasing their wheels (28, 29) from resting on the ground once the self-propelled device (1) has been made integral with the load (2).
Self-propelled device (1) according to any of the preceding claims, characterized in that it is designed capable of receiving, at the front portion (31), one or several accessories, namely hydraulically operated accessories.
