摘要： A lift truck 100 has an inertial damper 150 coupled between the base frame 116 and a A-frame holding a suspended wheel. The damper has a slider plate 170 frictionally engaged by friction pads 161, 169 on outer plate 160 and friction pads 181, 189 on the other outer plate 180. The outer plates 160, 180 are spring biased against slider plate 170 by belville washers 162, 182 or a coil spring 210.

摘要： A steerable vehicle having front and rear wheels is provided with a visual display for indicating the directional position of the wheels. The visual display, which is transparent, is vertically mounted on the vehicle within the normal forward view of the operator, enabling the operator to simultaneously view the display and maintain an unobstructed forward view. The visual display, which includes a transparent circuit card and an array of light emitting diodes (LEDs), may be mounted on the transparent mast guard of a forklift vehicle. A steering controller for a wheeled vehicle having a steerable drive wheel includes a computer containing reference data for the allowable range of the drive wheel directional position relative to the position of a second wheel, a switch coupled to the computer for selecting the directional position of the second wheel, and a transparent visual display coupled to the computer for indicating the position of the wheels. The display, which includes a transparent circuit card and an LED array, is vertically mounted on the vehicle within the operator's normal forward field of view. The controller provides for a visual signal to the operator when the directional position of the drive wheel approaches the limit of its allowable range and further provides for vehicle traction to cease when the position of the drive wheel transgresses its allowable range.
