Abstract: A joystick for a work vehicle includes a handle defining an external surface configured to provide grip for an operator of the work vehicle. The joystick includes hydraulic conditioning means configured to allow the passage of a conditioning fluid into joystick to regulate the temperature of handle.

Abstract: This invention relates to a device for reducing the reaction force of the supporting booms positioning cylinder of an earthmoving machine, comprising a braking system applied between the supporting booms of the machine which is operated during the time in which the positioning cylinder remains inactive, thereby unloading part of the reaction force of the cylinder, hence reducing the stress.

Abstract: An operative arm of an earth moving machine includes a dipper stick having a distal end, a bucket coupled to the distal end of the dipper stick, a hydraulic actuator coupled to the dipper stick, and a linkage generally interposed between the bucket and the hydraulic actuator. The linkage includes the following items: (i) a first lever rotatably coupled to the dipper stick and the hydraulic actuator, (ii) a linear actuator rotatably coupled to the dipper stick, (iii) a second lever rotatably coupled to the first lever and the linear actuator, and (iv) a bucket lever interconnecting the second lever, the linear actuator and the bucket.

Abstract: A wheeled vehicle including a chassis; an axle coupled to the chassis to oscillate about a longitudinal axis parallel to a direction of advance of the vehicle; a pair of cylinders disposed between the axle and the chassis for blocking oscillation of the axle; and a fixing assembly for fixing the cylinders to the chassis, the fixing assembly comprising a plate, a plurality of connection screws extending through the plate, at least one annular rest portion affixed in cantilever fashion to one of the chassis and the plate, the annular rest portion surrounding a corresponding one of the plurality of connection screws and defining a shoulder that supports the plate in a radial direction with respect to the axis of the connection screw.
