  • Publication number: 20240083728
    Abstract: A multifunctional lifting vehicle includes a frame, a telescopic arm having an attachment for mounting a piece of equipment, a drive system for operating the arm carrying the equipment, and a control system including a human-machine interface (HMI) device. The control system is programmed to determine a load diagram of the vehicle according to the type of equipment, and if the equipment connected to the arm belongs to a set of predetermined equipment stored in a memory of the control system. The controls system is also programmed for: detecting a new equipment connected to the attachment and sending a non-recognition signal, if the new equipment is not part of the set of predetermined equipment, displaying on the HMI a manual selection menu to select parameters of the new equipment, determining a new load diagram of the vehicle defined as a function of the parameters, and viewing the new load diagram.

  • Patent number: 6390764
    Abstract: A vehicle designed to be operated either as a lifting machine or as an agricultural tractor, comprising a bearing structure with motor-driven wheels, a control and driving cab, a telescopically extendable and retractable lifting boom arranged on one side of the control and driving cab and swingable relative to the bearing structure around a transverse axis located at the front end of the lifting boom, whose rear end carries a three-point hitch for agricultural implements to be operated by a rear power take-off. The lifting boom itself provides a power-lift for agricultural implements.

  • Patent number: 5199861
    Abstract: In a lifting truck of the type comprising a wheeled structure carrying a lifting arm articulated to the rear of the structure and a cab situated on one side of the structure at one side of the longitudinal axis of the structure, the internal combustion engine which propels the truck and operates the arm is disposed in a housing which is situated on the opposite side of the longitudinal axis to the cab and is spaced from the cab so as to form therewith a space at least as wide as the lifting arm. The arm is articulated to the structure of the truck in such a position that, in its completely lowered position, it is partly housed in the space so as not to interfere with the view of the operator working in the driving cab.

  • Patent number: 4755102
    Abstract: In a fork-lift truck comprising a wheeled structure carrying a lifting arm with a first part articulated at its rear end to the structure and a second part projecting downwardly from the front end of the first part and carrying a forked loading platform, and a jack for raising and lowering the arm, the lifting arm is supported by the wheeled structure so as to be orientable about a substantially vertical axis and two adjacent caliper units located in a general V configuration are provided to move the forked platform linearly relative to the lifting arm. Each caliper unit includes two plates having one mutual hinged articulation end and opposite articulation ends respectively hinged to the second part of the lifting arm and to the forked platform, the hinged articulations of the caliper units having respective axes which diverge downwardly and are substantially perpendicular to each other. Actuators are interposed between the two plates of each caliper unit for opening and closing them simultaneously.
