Abstract: 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.

Abstract: 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.

Abstract: 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.
