摘要： A materials handling vehicle is provided with a frame including an operator's compartment having an entrance, a drive mechanism supported on the frame, a material handling unit coupled to the frame, and a device including an actuator located across the threshold of the entrance of the operator's compartment. The device generates an alert signal when a portion of an operator's body engages the actuator.

摘要： A center controlled pallet truck includes a power unit located at a forward end of the truck, an operator platform in a central portion of the truck, load carrying forks located at a rear end of the truck, a steering arm mounted on and extending upwardly from a forward section of the power unit for controlling the direction of travel of the truck. A control handle mounted on said steering arm includes twist grips for controlling the speed of both forward and reverse movement of the truck. Each twist grip is provided with a generally horizontally disposed, forward facing paddle located at the outer ends of the twist grips to permit the outside fingers on the hand of an operator to move the paddle either upwardly or downwardly and thus rotate the twist grip with minimum force either while the operator is walking along side or riding on the truck.
摘要翻译：中央控制托盘车包括位于卡车前端的动力单元，卡车中心部分的操作平台，位于卡车后端的承载叉，安装在其上并从其向上延伸的转向臂用于控制卡车行进方向的动力单元的前部。安装在所述转向臂上的控制手柄包括用于控制卡车的正向和反向运动的速度的扭力夹。每个扭转夹具设置有位于扭转把手的外端处的大致水平设置的向前的桨，以允许操作者的手上的外指向上或向下移动桨，从而以最小的速度旋转扭转把手当操作者沿着侧面行走或骑在卡车上时。

摘要： Rigid floor panels define side edge channels which receive ribs formed on side edges of elastic mats so that the mats can be secured quickly to a floor panel, preferably without the need for adhesives, by engagement of the ribs with the channels. Pull tabs are formed on the mats to further secure the mats to the floor panels by extension through corresponding holes passing through the floor panels. Such pull tabs or some adhesive may be necessary for further securing the mats to the floor panels particularly when the floorboard is formed as two pieces and when the channels are one-sided. The shape and sizing of the ribs are such that they define matted floor corner edges giving the benefits of prior art matted floorboards but with substantially extended life expectancy.
摘要翻译：刚性地板镶板限定侧边通道，其接收形成在弹性垫的侧边缘上的肋，使得垫可以通过肋与通道的接合而快速固定到地板面板上，优选地不需要粘合剂。在垫子上形成拉片，以通过延伸通过穿过地板镶板的相应孔来将垫子进一步固定到地板镶板上。这样的拉片或某些粘合剂可能需要进一步将垫子固定到地板镶板上，特别是当地板块形成为两块时，以及当通道是单面的时。肋的形状和尺寸使得它们限定了地板角落的边缘，这给出了现有技术的地板地板的优点，但具有大致延长的使用寿命。
