Abstract: The invention relates to a method for starting and stopping an internal combustion engine of an industrial truck, wherein said industrial truck comprises an electric starter and an auxiliary hydraulic starter. Said method comprises steps of testing safety conditions (103), detecting instructions or requests from the operator (104), and testing auxiliary hydraulic starting conditions (105).

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 telescopic handling device includes at least two elements (1, 2) mounted so as to slide relative to one another with interposition of sliding shoes (3, 4). The device includes thinner holding elements (5, 6) for the sliding shoes so as to limit the separation between two sliding elements to the thickness of the interposed sliding shoes (3, 4).

Abstract: A device for suspending the cab of a vehicle includes a U-shaped main torsion bar (5) and a main actuator (3). The U-shaped main torsion bar (5) is positioned more or less along the longitudinal axis of the vehicle.

Abstract: A measuring device for a telescopic handling arm, in which the telescopic handling arm includes at least two elements (1, 2) that are mounted to slide relative to each other, includes measuring elements for measuring the extension of the telescopic arm. The device further includes calculation elements (4) for calculating the extension of the movable portion (2) of the telescopic arm using the hydraulic characteristics of a hydraulic telescoping actuator (3), and the device further includes adjuster elements for adjusting the calculated movements via a signal transmitted by at least one element (5, 6) for contactless identification of the position of the movable portion (2) of the telescopic arm.

Abstract: A truck includes at least three steered wheels (5, 6, 7) that are mounted on a chassis (1). The arrangement of the wheels relative to the chassis (1) is predetermined to increase the stability of the truck during the pivoting of the steered wheels (5, 6) and to protect the wheels in frontal mode.

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.
