Abstract
A dock leveler includes a frame. A deck plate is rotationally coupled to the frame at a deck hinge. A lip plate defines a lip plate lower surface and an edge. A lip hinge is coupled to the lip plate and a connection plate to provide relative pivotal movement of the lip plate and the deck plate. The connection plate is positioned below the deck plate. A support link extends from the lip plate to the connection plate. The support link is rotationally operable with respect to the lip plate and slidably operable with respect to the connection plate.
Claims19
A dock leveler comprising:
- a frame;
- a deck plate rotationally coupled to the frame at a deck hinge;
- a lip plate defining a lip plate lower surface and an edge;
- a lip hinge coupled to the lip plate and a connection plate to provide relative pivotal movement of the lip plate and the deck plate, the connection plate positioned below the deck plate;
- and
- a support link extending from the lip plate to the connection plate, the support link rotationally operable with respect to the lip plate and slidably operable with respect to the connection plate, wherein the support link remains entirely below the deck plate and is positioned between a flange of the connection plate and the deck plate, and wherein the support link slidably engages a connection pin that is coupled to a web of the connection plate.
A dock leveler comprising:
- a frame;
- a deck plate rotationally coupled to the frame at a deck hinge;
- a lip plate coupled to the deck plate at a lip hinge;
- a plurality of connection plates coupled to an underside of the deck plate;
- and
- a plurality of support links that are rotationally coupled to the lip plate;
- wherein:
- each support link of the plurality of support links slidably engages a respective connection plate of the plurality of connection plates;
- each support link includes a guide slot that slidably engages a corresponding connection pin attached to a respective connection plate;
- and
- rotational operation of the lip plate corresponds to rotational operation of the plurality of support links with respect to the lip plate and further corresponds to slidable operation of the plurality of support links with respect to the plurality of connection plates.
A dock leveler comprising:
- a deck plate rotationally coupled to a frame at a deck hinge;
- a lip plate coupled to the deck plate at a lip hinge;
- a connection plate attached to the deck plate;
- and
- a pair of support links that are rotationally coupled to the lip plate and slidably engage the connection plate, wherein rotation of the lip plate corresponds to rotational operation of the pair of support links at an eyelet of the pair of support links and also corresponds to slidable operation of the pair of support links with respect to the connection plate, wherein each support link of the pair of support links includes a guide slot that slidably receives a connection pin attached to a web of the respective connection plate, and wherein the web of the respective connection plate is positioned between each support link of the pair of support links.
