  • Patent number: 6119736
    Abstract: A vehicle for transporting wet objects in a manufacturing facility such as a push cart for transporting wet objects in a semiconductor fabrication plant is disclosed. The vehicle is equipped with a plurality of liquid-collecting trays wherein each of the trays is equipped with an inclined bottom panel with a drain hole at the lowest point and a horizontally positioned top panel equipped with a multiplicity of apertures. Liquid drained from the liquid-collecting trays is collected by a drain pipe into a drain tank mounted at the bottom of the push cart. The present invention novel push cart enables a wet object to be transported in the liquid-collecting trays in a relatively dry condition without contaminating other objects which are also carried in the tray. Furthermore, the present invention novel push cart prevents liquid from accidentally spilling out from the trays and causing personal injury or property damage.
