A dock leveler (10) for a truck (14) loading dock includes a pivotal deck (16) that is actuated by an inflatable column assembly (26a). The inflatable column assembly (26a) includes a pliable tube (44) that when inflated has a generally vertical cylindrical shape that can provide a heavy deck with substantial columnar support. The shape and orientation of the column assembly (26a) is such that the lengths of the pliable tube's seams are minimized. A pliable fabric sheet (80) held in tension against the underside of the deck (16) provides a generally flat, broad surface against which the pliable tube (44) can push as the inflatable column assembly (26a) pushes the deck (16) upward. A footed pallet (100) underneath the pliable tube (44) can be banded to the deck (16) during shipment. After installation, the pallet (100) can be readily lifted for cleaning the pit floor underneath the pallet (100).
L'invention concerne un niveleur de quai destiné à un quai pour le chargement de camions. Ledit appareil comprend un plancher pivotant actionné par un ensemble colonne gonflable. Cet ensemble colonne gonflable comprend un tube pliable qui, lorsqu'il est gonflé, présente une forme cylindrique sensiblement verticale qui peut assurer un support sensiblement colonnaire à un plancher lourd. L'ensemble colonne présente une telle forme et orientation que les longueurs des jointures de tube pliables sont minimisées. Une garniture textile pliable maintenue sous tension contre la face inférieure du plancher procure une surface sensiblement plate et large. Cette garniture peut supporter la pression exercée par le tube pliable venant contre elle lorsque l'ensemble colonne gonflable pousse le plancher vers le haut. Une palette à pied sous le tube pliable peut être liée au plancher pendant le chargement. Après l'installation, la palette peut être soulevée facilement pour nettoyer le sol de la cuvette sous la palette.
