摘要： A multi-task capable work assist vehicle is designed for transporting an operator and items to be handled by the operator and for elevating the operator with such items supported upon a load tray elevated with the operator. Preferably the load tray is mounted for positioning along a telescoping mast which supports and elevates the operator. A load deck or load platform is provided on a body of the vehicle in addition to the load tray so that items such as packages, tools, parts, merchandise and the like can be carried by the vehicle. Load shelves may also be provided adjacent the load deck to add flexibility and capacity to the load carrying capability of the vehicle. Uses of the vehicle include order picking, in-house service maintenance, stock management, cargo delivery and the like. It is designed to be compact in size and highly maneuverable for use in narrow storage aisles and tight quarters.

摘要： A pallet clamping device is mounted between forks of a material handling vehicle. The device clamps to a stringer of a pallet using a pair of horizontally moveable jaws. The jaws are resiliently forced toward one another for clamping a stringer so that a clamped pallet will not move off the forks. The jaws are mounted for pivoting and sliding motion relative to mounting pins which, together with links coupling the jaws to a base of the device, tighten jaw closure if a pallet moves away from the forks. The pivoting and sliding motion of the jaws helps align the jaws with pallets not perfectly aligned with the vehicle. Depression of a foot pedal moves the jaws from a closed position to a latched open position for receiving a pallet stringer. The jaws can also be moved to an unlatched open position for receiving a greater width center stringer. Upon release of the operating device from the unlatched open position, the jaws move toward their closed position.
摘要翻译：托盘夹紧装置安装在材料处理车辆的叉之间。该装置使用一对水平移动的夹爪夹紧到托盘的纵梁上。夹爪相互弹性地相互夹紧，以夹紧桁条，使得夹紧的托盘不会从叉子上移开。夹爪安装成相对于安装销枢转和滑动运动，如果托盘远离货叉移动，连接钳口的装置与装置的基座一起紧固钳口闭合。夹爪的枢转和滑动运动有助于使夹爪与车辆不完全对准的托盘对齐。踏板踏板将颚板从关闭位置移动到锁定的打开位置，以接收托盘纵梁。夹爪也可以移动到未锁定的打开位置，以接收更大的宽度中心纵梁。当操作装置从解锁的打开位置释放时，夹爪朝着关闭位置移动。

摘要： A knurled wheel is coupled to a sensor mounted to one mast member and the wheel is forced into another mast member so that the wheel/sensor rotate upon mast movement. The sensor generates signals, corresponding to mast movement, which are processed conventionally to determine mast height, etc. The knurled wheel forms a track on the contacted mast member and the knurl engages the track. The wheel can be forced into the mast member with a force of six to nine pounds. To enhance the versatility of the mast height sensing device, the thickness of the wheel can be made less than ⅛ inch, for example {fraction (1/16)} inch. The sensor can be an encoder or a sensor bearing and a heater can be provided for operation in cold environments to ensure rotation of the sensor under such conditions.
摘要翻译：滚花轮联接到安装到一个桅杆构件上的传感器，并且该轮被迫进入另一个桅杆构件，使得车轮/传感器在桅杆运动时旋转。传感器产生对应于桅杆运动的信号，其通常被传统地处理以确定桅杆高度等。滚花轮在接触的桅杆构件上形成轨道，并且滚花接合轨道。车轮可以用六到九磅的力量被迫进入桅杆构件。为了增强桅杆高度感测装置的多功能性，轮的厚度可以小于1/8英寸，例如1/16英寸。传感器可以是编码器或传感器轴承，并且可以提供加热器以在寒冷的环境中操作，以确保在这种条件下传感器的旋转。
