Abstract: A personnel carrying vehicle comprising a self propelled, steerable body, a telescoping mast attached to and extending upwardly from said body, and a personnel compartment attached to the mast and provided with a rail member that extends from the mast and around the sides. A pair of gate members, which are pivotally attached to the rail member and to the floor of the compartment, are movable from a closed position to an open position wherein said gate members extend into the compartment. The mast extends upwardly and forwardly of the body at an angle of approximately five degrees to the top of the rail; this provides the operator with unobstructed access to anything above the top edge of the rail, and the forward tilt of the mast enlarges the upper portion of the compartment, near the waist of the operator, thus accommodating the operator comfortably without increasing the length of the vehicle; it also causes the center of gravity of the vehicle to move forward, toward the center of the vehicle, as the compartment is raised. The vehicle is driven by electric motors which are located under the operator compartment and attached to the drive wheels through gear trains to permit the floor of the compartment to be positioned as close to the ground level as possible. Control handles are mounted within the personnel compartment, with one handle controlling steering and the other handle controlling traction. Sensors ensure the operator's hands are on both control handles and both feet are properly positioned on the floor before the vehicle can be moved or the platform raised; this ensures a four point stance, providing for operator stability and that the operator's hands and feet are within the operator's compartment anytime the vehicle is being moved or during lifting or lowering operations. Gate interlock switches are provided to restrict or prevent travel of the vehicle under certain conditions. A load deck is provided on the body of the vehicle on the opposite side of the mast from the personnel compartment. Also, a load tray may be mounted to the telescoping mast to move vertically with the compartment. Rail guides may be mounted to the outside of the vehicle to facilitate entry into and operations within narrow aisles.

Abstract: A fork lift truck includes a fork level sensor located in the forks, away from the vertical mast of a lift truck for detecting the true level of the forks, and a vision system including a camera which may take several forms. In one form, a single camera is mounted in a housing which may be moved to a protected location vertically either by sliding in the carriage assembly, or by use of a parallelogram device. In another form, multiple cameras are employed where a second camera may either mounted above the first camera in the same housing or mounted between the forks. Alternatively, the first camera may perform multiple roles by being moved vertically from a first predetermined location below the bottom of the forks to a higher elevation a second predetermined location relative to the forks. A video display terminal, which shows the view observed by the camera, may also include a fork level indicator, a reticle for assisting in adjusting the vertical position of the forks, and an indicator showing the specific truck function selected by the operator.

Abstract: An end of aisle control system permits an operator controlled materials handling vehicle to be configured by following instructions given on a service terminal and easily positionable magnet sensors to a customer's specific operating environment. In addition to end of aisle magnets that are buried in specified paths in the floor of a warehouse, magnets may be buried in other paths to accomplish specified functions, such as auto-resume and end aisle blocked. The buried magnets identify zones of operation and a microprocessor controls the maximum speed of travel in each of these zones. The maximum speed of the vehicle in each of the specified zones may be pre-selected according to the direction of travel of the vehicle, thus making the control system adaptable to a wide variety of operating environments. The end of aisle control system also controls the method of stopping the vehicle, either by the use of brakes, or by plugging the traction motor. Whenever the vehicle is stopped in response to action by the end of aisle control system, an audible and visual signal is presented, indicating that specific operator action is required before further movement in that same direction is possible.

Abstract: A materials handling vehicle employs a two step braking process where full brakes are applied to stop the vehicle quickly when it is traveling at a fast rate, and partial braking force is applied to stop the vehicle smoothly when it is traveling slowly. The amount of the braking force is controlled by the spring force applied to the braking shoes. Whenever the vehicle is moving at or less than a predetermined speed, only the brakes on one pair of wheels, typically the load wheel brakes, that is the brakes on the wheels under the load, will be used when braking action is requested. This will permit the vehicle to stop smoothly, and not abruptly as would be the case if full braking were to be applied. If the vehicle is moving faster than the predetermined speed, then full braking force will be applied by actuating the brakes on both pairs of wheels whenever requested by the operator or by the vehicle control system. Both the load wheel brakes and the steered wheel brakes are conventional spring applied brakes which are released by hydraulic pressure applied to individual brake cylinders.
Abstract translation: 材料处理车辆采用两步制动过程，其中应用全制动器以快速行驶时快速停止车辆，并且施加部分制动力以在缓慢行驶时平稳地停止车辆。 制动力的量由施加到制动靴的弹簧力控制。 每当车辆以预定速度移动或小于预定速度时，只有在要求制动动作时，将使用一对车轮上的制动器（通常是负载轮制动器），即在负载下的车轮上的制动器。 这将允许车辆平稳地停止，而不是突然地如同使用全制动的情况那样。 如果车辆移动速度比预定速度快，那么当操作者或车辆控制系统要求时，通过在两对车轮上执行制动来施加完全制动力。 负载轮制动器和转向轮制动器都是常规的弹簧施加制动器，其通过施加到单个制动缸的液压被释放。

Abstract: The lifting mast (20), frame (12), and outriggers (16) of a slip sheet lift truck (10) are fixed and immovable with respect to one another. The platen (30), push-pull mechanism (45), and back plate (31) are an integral unit mounted to permit side shifting on a tilt carriage (29), which is mounted on lower pivots (28) and tiltable thereabout with upper tilt cylinders (35). These are carried on a lifting carriage (25) which is vertically moveable and supported by a lifting cylinder (26) on the lifting mast (20). The lift truck outriggers (16) extend and slope forwardly and downwardly from the mast (20) to provide better truck stability, clearance for the platen (30), and good underclearance for ramps and dockboards.

Abstract: An improved switch assembly for use with a materials handling truck includes a pair switches that are conveniently placed in a natural position for actuation by an operator while walking along side the truck. The pair of switches are so placed on each side of a steering control handle to prevent inadvertent actuation and therefore inadvertent operation of the truck. One of the pair is operated by the thumb while the other is positioned to be operated by the fingers as the operator grasps the handle. A control circuit responds to the operation of both switches on one side to move the truck forward at a predetermined speed.
