摘要： Use of a laterally-shiftable C-shaped frame which supports an auxiliary mast above its upper and lower extremities allows a lift truck to handle wider loads in a given aisle width, and decreases bending moments and inertial forces.

摘要： To enable a vehicle which can automatically track a substantially straight guidewire or the like at high speeds with prescribed dynamic characteristics to also track distinct guidewire curves with similar characteristics, an added signal which is a function of guidewire curvature and vehicle wheelbase is superimposed on the command signal derived from a tracking sensor to modify the command signal applied to a steering servo or other steering means while the vehicle negotiates a curve.

摘要： Two-phase logic signals from a reversible shaft encoder or like device provide count occurrence pulses and a count direction logic signal to control incrementing and decrementing of a counting means. One count occurrence pulse is omitted each time the count direction changes to avoid errors which otherwise might result. Up counts and down counts occur at the same shaft encoder positions, and the system has high noise immunity.

摘要： Provision of an auxiliary mast which is tiltable, as well as being laterally shiftable and rotatable about a vertical axis, allows loads to be handled without the top of the mast damaging previously-stored loads or limiting fork entrance into a storage rack.

摘要： The fork carriage of a side-loader truck is journalled for rotation about a vertical axis between two arms, one above and one below the carriage, which transmit lateral load moments to a narrow vertical member. A vertically-extending torque shaft journalled on the vertical member carries gears on its opposite ends. The gears engage laterally-extending racks spaced widely vertically apart on a rearward carriage, so that lateral load moments apply minimum forces to the racks, and rotation of the torque shaft also serves to laterally position the vertical member and the fork carriage. The rearward carriage may comprise an elevatable, mast-guided laterally-fixed carriage, or an intermediate carriage may be interposed between the vertical member and the laterally-fixed carriage to provide greater lateral load extension. An intermediate carriage having a roller arrangement insuring adequate support at any lateral load position is shown. By mounting the truck load wheels on the ends of an axle member, a given truck design can be readily adapted for use in aisles by numerous different widths without changes in a heavy welded base frame of the truck.
摘要翻译： 侧装载机卡车的托架支架用于围绕两个臂之间的垂直轴线旋转，一个在托架上方和一个下方，从而将横向载荷力矩传递到一个狭窄的垂直构件。 轴向安装在垂直构件上的垂直延伸的扭矩轴在其相对端承载齿轮。 齿轮啮合横向延伸的在后托架上垂直分开的横向延伸的齿条，使得横向载荷力矩对机架施加最小的力，转矩轴的旋转也用于横向定位垂直构件和叉架。 后部托架可以包括可升降的桅杆引导的横向固定的滑架，或者中间滑架可以插入在垂直构件和横向固定的滑架之间以提供更大的横向载荷延伸。 示出了具有确保在任何横向负载位置处具有足够支撑的辊布置的中间托架。 通过将卡车装载轮安装在车轴构件的端部上，给定的卡车设计可以容易地适用于通过多个不同宽度的通道，而不改变卡车的重型焊接底座框架。

摘要： Extendable mast systems and methods for a material handling vehicle include a base mast having a first web connecting a first web first flange and a first web second flange; a base mast bearing; a base mast bumper; a vertically extendable mast having a second web connecting a second web first flange and a second web second flange; and a vertically extendable mast bearing. The base mast bearing is spaced apart from the second web first flange defining a base mast bearing space between the base mast bearing and the second web first flange. The vertically extendable mast bearing is spaced apart from the first web first flange defining a vertically extendable mast bearing space between the vertically extendable mast bearing and the first web first flange. And the base mast bumper maintains the base mast bearing space between the base mast bearing and the second web first flange.
