Abstract
A dock leveler comprises a deck plate and a lip assembly hingedly connected to the deck plate. The lip assembly comprises a lip plate and a lip subplate. The lip plate includes a traction side and a bottom side and has a lip plate crown. The lip subplate includes a top side and a bottom side and has a lip subplate crown. The lip subplate is coupled to a bottom side of the lip plate in a manner that provides structural rigidity to the lip plate. The lip subplate crown is aligned and nested with the lip plate crown.
Claims20
A dock leveler comprising:
- a deck plate;
- and
- a lip assembly hingedly connected to the deck plate, the lip assembly comprising:
- a lip plate including a traction side, a bottom side, a lip plate crown, and a distal end;
- and
- a lip subplate including a top side, a bottom side, a lip subplate crown, and a distal end, the lip subplate coupled to a bottom side of the lip plate in a manner that provides structural rigidity to the lip plate, wherein the lip subplate crown is aligned and nested with the lip plate crown, and wherein the distal end of the lip plate extends beyond the distal end of the lip subplate.
A lip assembly on a dock leveler, comprising:
- a lip plate including a traction side, a bottom side, a lip plate crown, and a distal end;
- and
- a lip subplate including a top side, a bottom side, a lip subplate crown, and a distal end, the lip subplate coupled to a bottom side of the lip plate in a manner that provides structural rigidity to the lip plate, wherein the lip subplate crown is aligned and nested with the lip plate crown, and wherein the distal end of the lip plate extends beyond the distal end of the lip subplate.
A lip assembly on a dock leveler, comprising:
- a lip plate including a traction side and a bottom side and having a lip plate crown;
- and
- a lip subplate including a top side and a bottom side and having a lip subplate crown, the lip subplate coupled to a bottom side of the lip plate in a manner that provides structural rigidity to the lip plate, wherein the lip subplate crown is aligned and nested with the lip plate crown,
- wherein the lip plate comprises a proximal end and a distal end, the proximal end being disposed adjacent a deck plate, and wherein the lip subplate also comprises a proximal end and a distal end, a portion of the proximal end of the lip plate and the proximal end of the lip subplate being aligned.
A dock leveler comprising:
- a deck plate;
- and
- a lip assembly hingedly connected to the deck plate, the lip assembly comprising:
- a lip plate including a traction side and a bottom side and having a lip plate crown;
- and
- a lip subplate including a top side and a bottom side and having a lip subplate crown, the lip subplate coupled to a bottom side of the lip plate in a manner that provides structural rigidity to the lip plate, wherein the lip subplate crown is aligned and nested with the lip plate crown, wherein the lip plate has a lip plate width and the lip subplate has a subplate width, the subplate width being in a range of about 20-70% of the lip plate width.
