Title:

CONVEYANCE APPARATUS WITH LIFTING/LOWERING LOAD CARRYING PLATFORM

Document Type and Number:

WIPO Patent Application WO/2006/022121

Kind Code:

A1

Abstract:

A lifting stroke of a load carrying platform (3), liftably/lowerably supported through a cross link (13a), of a traveling body (1) for conveyance is increased with a low floor structure of the traveling body (1) maintained. In a conveyance apparatus having a lifting/lowering load carrying platform, there are laid a first cam rail (47A) acting on a first to-be-operated section (28) to lift a load carrying platform (3) to an intermediate height (H1) and a second cam rail (48) acting on a second to-be-operated section (29) to lift the platform (3) from the intermediate height (H1) to the maximum height (H2). The second to-be-operated section (29) is provided at an intermediate folding fulcrum (36) of a toggle link (32) interposed between the cross link (13a) and a fixation position on the traveling body (1) side. When the platform (3) is lifted to the intermediate height (H1), the toggle link (32) is extended such that both upper fulcrums (37, 39) are separated, relative to the intermediate folding fulcrum (36), to both the front and rear in the traveling direction. The second to-be-operated section (29) in this extended state of the toggle link (32) is positioned below the first to-be-operated section (28) in the same state.
