摘要： A fork lift truck includes a body, a drive mechanism supported on the body for effecting movement of the body, and a fork carrying assembly carrying forks which can be moved in height between a lowered position and desired raised positions. A tilt cylinder is provided for tilting the forks through a fork tilt range. The truck further includes a pressure sensor capable of generating signals indicative of the weight of a load on the forks, a fork tilt position sensor capable of being activated when the forks are tilted to extremes of the fork tilt range, and a controller. The controller is coupled to the drive mechanism, the pressure sensor and the fork tilt position sensor. It causes the drive mechanism to effect movement of the body up to a first maximum speed when at least one of the pressure sensor generates a signal indicative of a load on the forks having a weight above a predetermined value and the tilt position sensor is activated, and causes the drive mechanism to effect movement of the body up to a second maximum speed which is greater than the first maximum speed when the pressure sensor generates a signal indicative of no load or a load on the forks having a weight below the predetermined value and the tilt position sensor is inactivated. The lowering speed of the forks can also or alternatively be increased under the same operating conditions.

摘要： A fork lift truck capacity monitor or alerting device informs operators of the weight on the forks and fork height and alerts operators whenever truck speed is above creep with the forks raised above a collapsed height or whenever the forks are raised above a recommended height for a given load. The alerting device includes a control circuit that receives inputs from a speed sensor, a fork height sensor and a weight sensor and reads a memory storing data correlating load weights with maximum recommended fork heights. A truck icon is displayed on a display panel. A plurality of height zone lamps representing the weight of the load on the forks are arranged in a vertical column over the truck icon and selectively illuminated according to the load on the forks. A plurality of lamps represent the height of the forks with the fork height lamps, which include one lamp positioned to represent a lowered position of the forks and a plurality of lamps equal in number to the height zone lamps and placed horizontally opposite therefrom, being selectively illuminated according to the height of the forks. An alarm signal alerts operators whenever the forks are raised above the recommended height for a given load weight, or whenever truck speed exceeds a predetermined maximum speed and the forks are above the collapsed height. The alarm signal may include a combination of an audible signal, a text message, and a flashing lamp.
摘要翻译：货叉车容量监视器或警报装置通知叉车叉车高度时的重量，并提醒操作人员，只要卡车速度高于蠕变速度，叉子升高到塌陷高度以上，或者当货叉抬高到建议高度时，给定加载。警报装置包括控制电路，其接收来自速度传感器，叉高度传感器和重量传感器的输入，并且读取存储与负载重量相关联的数据与最大推荐叉高度相关联的存储器。显示面板上显示卡车图标。表示叉子上的负载重量的多个高度区域灯被布置在卡车图标上的垂直列中，并根据货叉上的负载选择性地照亮。多个灯表示具有叉高度灯的叉的高度，其包括定位成表示叉的降低位置的一个灯和与高度区灯数量相等并且与其水平相对放置的多个灯，选择性地根据叉子的高度照亮。每当叉子升高到给定负载重量的推荐高度之上时，或者当卡车速度超过预定最大速度并且货叉高于折叠高度时，报警信号会提醒操作员。警报信号可以包括可听信号，文本消息和闪烁灯的组合。

摘要： An improved pallet truck, having an extended length pair of forks capable of supporting multiple, side-by-side, pallets which may be raised well above the floor to assist an operator in an order selection operation, includes a first fork lifting mechanism connected to one end of a pair of primary forks. A pair of load wheels are mounted on levers at a other end of the forks and are mechanically connected to the first fork lifting mechanism which causes the other end of the primary forks to be raised from a lower level to an upper level simultaneously with the raising of the first end thereby to maintain the primary forks level while lifting the maximum capacity of the truck. A pair of secondary forks are mounted above the primary forks and are movable from a nested position with respect to the first forks to a raised position by a second fork lifting mechanism carried by the primary forks. The ends of the secondary forks are supported by a pair of hydraulic cylinders attached between the secondary forks and the primary forks, thus providing support and rigidity to the secondary forks while they are in a raised position.
摘要翻译：一种改进的托盘车，具有能够支撑多个并排的托盘的延长长度的一对叉，其可以在地板上方很好地升高以帮助操作者进行订单选择操作，包括连接到一对主要叉的一端。一对负载轮安装在叉子的另一端的杠杆上，机械地连接到第一叉式提升机构，这使得主叉的另一端在升起时同时从较低水平升高到较高水平从而在提升卡车的最大容量的同时保持主叉架水平。一对次叉被安装在主叉上方，并且可以通过由主叉承载的第二叉提升机构从相对于第一叉的嵌套位置移动到升高位置。二级叉的端部由附接在辅助叉和主叉之间的一对液压缸支撑，从而在辅助叉处于升高位置时为辅助叉提供支撑和刚度。
