    摘要： A lift truck control system which utilizes a distributed control network including at least a display module, a distribution module, a traction module, a brake module and a steering module. The display and steering modules each are configurable by software which controls the module and the various drivers in each module. In the preferred embodiment, the display module includes flash memory which stores application software and can be rewritten so that the performance characteristics of the modules are software configurable. The display module is connectable to a programmable cartridge which includes nonvolatile flash memory that carries application software for the display and steering modules. When connected, the cartridge downloads the particular application software which is written over the stored software in flash memory for the display and steering modules. The programmable cartridge also can be used to store and download boot software to the display and steering modules, so that the boot procedure performed by the display and steering modules is also software configurable. The system accepts modules which can be installed in a variety of different lift truck vehicles with minimal physical changes; the performance of the modules is configured by the application software written into the flash memory of the module.

    摘要： In a material handling vehicle having an operator platform, a sideshift carriage mounted for lateral movement relative to the platform, a traverse carriage mounted for lateral movement relative to the sideshift carriage and forks mounted to the traverse carriage, an improved sideshift control system monitors the position of the sideshift carriage to define home positions for the sideshift carriage relative to the platform. Two home positions are defined, one for the forks facing to each side of the vehicle. The home positions offset the sideshift carriage to one or the other side of the platform to substantially center the load on the vehicle such that a portion of the base of the forks extends a set distance beyond one side of the platform, and the load supported on the forks extends approximately an equal distance beyond the opposite side of the platform. Two electrical switches are mounted approximately at the center of the platform opposite to the sideshift carriage and an activating plate includes two projections which operate alternate ones of the two switches dependent upon the direction the sideshift carriage is extended. A variety of actuating plates conveniently change the home positions and, hence, the preferred load carrying position of the forks for selected applications.

    摘要： A variable braking force electric brake for materials handling vehicles, such as fork lift trucks, utilizes two sets of springs to urge brake pads against a rotor of a disc brake. The first set of springs provide a first level of braking force, typically one-third of the total braking force. The second set of springs provide a second level of braking force, typically two-thirds of the total. A pair of electromagnetic elements act on armatures placed between the springs and a non-magnetic brake pad support plate to selectively permit either the first set of springs alone to provide braking, the second set of springs alone, or both sets together. Initially, the current to the electromagnetic elements is strong, to insure that the associated armature is pulled toward the electromagnet, and afterwards, the current is reduced to minimize heating and power requirements. The space or gap between the electromagnets and the armatures may be ascertained by means of a feeler gauge, or be examining a plunger, the end of which extends through the outer housing of the brake. The gap is determined by a set of three adjusting screws placed around the periphery of the brake housing.

    摘要翻译： 用于物料搬运车辆的可变制动力电动制动器，例如叉式起重车，利用两组弹簧来将刹车片推向盘式制动器的转子。 第一组弹簧提供第一级制动力，通常是总制动力的三分之一。 第二组弹簧提供第二级的制动力，通常为总数的三分之二。 一对电磁元件作用在放置在弹簧和非磁性制动衬块支撑板之间的电枢上，以选择性地允许第一组弹簧单独提供制动，第二组弹簧单独或两者组合在一起。 最初，到电磁元件的电流很强，以确保相关联的电枢被拉向电磁体，之后电流被减小以最小化加热和功率要求。 电磁铁和电枢之间的空间或间隙可以通过测距仪来确定，或者检查柱塞，其柱端延伸穿过制动器的外壳。 间隙由围绕制动器壳体的周边设置的一组三个调节螺钉来确定。
