Abstract: The invention relates to a modification system for modifying the steering ratio for a vehicle having steered wheels (11), a steering wheel (10), and a steering transmission device (20) serving to transmit steering movement between the steering wheel (10) and the steered wheels (11) with a steering ratio R=Alpha/Beta, where Alpha is the turning angle of the steering wheel, and Beta is the steering angle of the wheels; said system comprising a device for determining the angular speed of the steering wheel. Said system comprises a module (102) for controlling the steering ratio R configured to calculate the steering ratio as a function of the angular speed of the steering wheel (10). The invention also relates to a wheeled vehicle fitted with such a steering ratio modification system.

Abstract: A lift truck with variable range with at least three wheels and a telescopic arm. The lift truck includes a steerable rear wheel and two front wheels, a driver station and a motor propulsion group secured to a chassis. The chassis has a compact configuration and is elongated in the longitudinal direction of advance of the truck, and has safety elements against the risk of loss of lateral stability. The safety elements are adapted to oppose turning over of the truck. The truck also includes a device to limit the maximum speed of advance based on a turning angle of the steerable wheel.

Abstract: The device for interactive control with the hand of an operator, particularly of an operator of machinery or material or an engine with multiple functions, comprises a configuration for interaction with the palm of the hand, so as to avoid the gripping of the fingers of the operator on the device, thus permitting an interaction of the palm and fingers of the operator with the device for the accomplishment of multiple functions.

Abstract: An automotive vehicle with a telescopic load carrying arm 30, comprises a rigid chassis 32 carried by two front and rear axles 1 and 2, a driver's cab 33 and a support 31 for articulation of a telescopic load charging arm 30 disposed in front of the cab 33. The chassis 32 has a first compartment 34 containing an internal combustion motor 21 and a radiator 23, a second compartment 35 containing two reservoirs of onboard fluid, and a securement 36 adapted to receive agricultural tractive equipment.

Abstract: A gearbox, particularly for an automotive vehicle with a telescopic load-carrying arm, is adapted to transmit directly or indirectly the drive movement of an internal combustion motor (M) with at least one front or rear axle provided with driven wheels. This gearbox includes a casing (13) containing an angled transmission (15) arranged to transmit the movement of the output shaft (17) of the motor, to a drive shaft (9 or 10) of the front or rear axle, or both. The gearbox further comprises a power takeoff through shaft (16) arranged to drive a pump that generates hydraulic or hydrostatic energy.

Abstract: A fork lift truck, adapted to be loaded on the rear of a carrying vehicle includes a chassis 1 bearing at least one power driven and steering rear wheel 8 and two fixed direction front wheels 16, 17. The front portion 2 of the fork lift truck that includes a mast 21 and two front wheels 16, 17, is pivotally interconnected to the chassis 1 about a vertical axis 3 so as to pivot between a use position in which the front portion 2 of the fork lift truck is aligned with the chassis 1 and a loading position in which the front portion 2 and the chassis 1 are perpendicular to each other.

Abstract: A backhoe elevator includes a front, loading arm supported on a frame forward of a driver cab midway between front and rear axles. The frame includes two spaced apart elongated members that define a space for retraction of the arm between the members. The controls for the loading arm are disposed along a central axis of the backhoe elevator. The engine is transversely mounted and includes two outputs, one for a hydraulic pump and one for a gear box that is below the support for the loading arm between the frame members. The support for the loading arm may include two parallel plates, one of which is a vertical extension of one of the elongated members and the other of which is mounted on an upper plate that is between and perpendicular to the elongated members. One of the elongated members may have a rear portion that is curved outwardly so that it is not parallel to the other of the elongated members.

Abstract: A device for securing a goods handling carriage (1) on a truck, comprises a support chassis (11) provided with first anchoring and securing structure (14a, 15a) to secure the chassis (11) on the bed (3) of the truck, and second anchoring and securing structure (14b, 15b) to secure the chassis (11) below the truck bed (3).

Abstract: A motorized lift truck, with a telescopic arm (9), comprising a chassis (1) mounted on a plurality of wheels of which at least one (7) is power driven. The chassis (1) carries a motor propulsion group (3), a cab (2) and lifting structure (4) disposed between the motor propulsion group (3) and the cab (2). The lifting structure (4) is the telescopic arm (9) mounted pivotably about a substantially horizontal axle (10). The assembly of the lifting structure (4) comprising the telescopic arm (9) is displaceable transversely, so as to permit precise adjustment over a predetermined distance (d) of the position of the lifting structure (4) so as to engage the load. The truck is adapted to be loaded up on the rear of a carrying vehicle and comprises a chassis (1) having a U shape.

Abstract: A lift truck 1 with a telescopic arm 3 comprises a front axle 6 and a rear axle 7 and a mechanical transmission to transmit the movement of the drive train 5 to the forward 6 and/or rear 7 axle or axles. The drive train 5 is oriented transversely to the truck 1 and the mechanical transmission is located in a central position. This arrangement permits easy access to the drive train and rapid exchange of the latter, so as to facilitate the maintenance and reduce the down time of the lift truck.
