  • Publication number: 20070289798
    Abstract: A forklift apparatus with improved all-wheel steering includes: a chassis; a plurality of wheels; at least one motor; a plurality of idler pulleys; a plurality a traction belts; and a plurality of actuators. The plurality of wheels supports the chassis from a ground surface and steer the chassis on the ground surface. The at least one motor is operatively connected to at least one of the wheels to rotate the wheel about a horizontal axis. Each wheel is rotationally mounted to the chassis about a vertical axis. Each wheel has a drive pulley oriented horizontally above the wheel and centered on the axis and connected to rotate with the wheel about the vertical axis. Each idler pulley is rotationally mounted to the chassis about a vertical axis and spaced from one of the drive pulleys. Each traction belt is wrapped around one pair comprising an idler pulley and a drive pulley.

  • Publication number: 20070289791
    Abstract: A sideloader forklift vehicle has a chassis supported on a plurality of wheels, a forklift mechanism supported on the chassis, an operator's cab supported on the chassis, and a battery cabinet supported on the chassis for electrically powering the sideloader forklift vehicle. The battery cabinet is elongated along a line parallel to the cab side edge of the chassis and has a cab side face located at a distance from the cab side edge whereby an operator within the operator's cab has a clear line of vision to a corner of the chassis defined by the cab side edge and the front end edge of the chassis. A side cabinet is provided between the cab side face of the battery cabinet and the cab side edge of the chassis, tapered in height from the cab to the front end edge of the vehicle chassis.

  • Patent number: 5284393
    Abstract: A sliding bearing (10) having an inner surface (13a) provided with at least one circumferential recess (15, 16) extending over a portion of the axial dimensions of the inner surface (13).The recess (15, 16) is located over one portion of the inner surface (13a) which is subjected to a peak oil film pressure (POFP) higher than a minimum value previously calculated for, and/or located up to 45 degrees upstream considering the rotation direction of the shaft, in one region of the inner surface (13a) where the minimum oil film thickness (MOFT) is less than a value previously calculated. Each circumferential recess (15, 16) is defined by a maximum radial depth E, a circumferential range given by the angle .alpha., which vary according to construction and operational features of the bearing (10), in order to cause the values of pressure and/or oil film thickness to meet values previously calculated for the bearing (10).

  • Patent number: 5000586
    Abstract: A sliding bearing of the type comprising a backing layer; an intermediate layer provided with internal peripheral grooved portions crosswise the bearing length and longitudinally spaced from each other; optionally, a diffusion or bonding layer on the grooved portions; and a sliding layer of a material softer than the material of the intermediate layer and filling the grooved portions. According to the invention, the grooves of the grooved portions have a depth and longitudinal spacing with uniform or variable dimensions, wherein at least one of the characteristics of depth and spacing is mandatorily variable. This design allows a selective distribution of harder material and softer material on defined portions of the bearing as a function of specific operating requirements.
