  • Publication number: 20080047211
    Abstract: A sealing curtain adapted to seal against a vehicle parked against the sealing curtain is described. The sealing curtain includes a sealing surface for engaging the parked vehicle and a heat shield adjacent the sealing surface. The heat shield has a higher thermal conductivity than the sealing surface to dissipate heat from the parked vehicle across the sealing curtain and includes a plurality of heat shielding layers such that an air interface is present between adjacent heat shielding layers.

  • Publication number: 20070101517
    Abstract: A shield system for shielding the area underneath a dock leveler allows a gap to be created either above or below the shield when the deck rises, whereby a shield of a given height dimension can used on dock levelers of various lift heights. In some embodiments, the shield is a pliable curtain that a tensioner holds taut during some operations of the dock leveler, yet the curtain can collapse for below-dock operation. The shield system can be used on horizontally storing dock levelers or vertically storing ones. In some cases, the system includes a pliable web that extends between a front face of the deck and a lip extending from the deck. The web can help seal the area adjacent to a pair of dock bumpers.

  • Publication number: 20060272222
    Abstract: A sealing curtain for a loading dock includes a pliable heat shield that helps protect the sealing curtain from concentrated heat generated by a truck's taillight being pressed against the sealing curtain. The heat shield is preferably placed just underneath a sealing surface of the sealing curtain. The heat shield reflects heat away from an inner surface and disperses the heat over a broader area to reduce the peak temperature of any hot spots. The sealing curtain may be height adjustable to position the heat shield at various heights along the loading dock.
