Abstract:
A vehicle for handling coils comprising:a) a wheeled bridging frame structure, a tunnel formed by the frame structure extending along the vehicle, the tunnel having dimensions for allowing passage of the vehicle above a coil laying on a ground and the tunnel having an axis oriented parallel to the ground and perpendicular to a longitudinal axis of the vehicle; b) the bridging frame structure comprising a pair of framework longitudinal members, a distance between the pair of longitudinal members corresponding to or being slightly greater than an axial dimension of the coil, and a transverse structure connecting the pair of longitudinal members disposed at a height greater than a diameter of the coil; c) an upper aperture in the tunnel between the pair of longitudinal members, the aperture having dimensions for allowing the coil to pass therethrough and to be lifted above a height of the tunnel; d) a gripper mounted on the bridging frame structure for gripping and lifting the coils; e) an operating cab and a motor mounted on the bridging frame structure; whereinf) the transverse structure is limited to a rear half of the bridging frame structure; g) the upper aperture of the tunnel is open at a front end of the bridging frame structure; and h) the gripper for lifting the coils further comprises a crane comprising a lifting boom articulated to a rear end of the vehicle at a rear of the transverse structure.
