Dock leveler sealing systems
Dock leveler sealing systems are disclosed herein. In various embodiments, a dock leveler sealing system can include a bottom seal configured to be attached to an underside of a dock leveler deck and extend transversely thereto, and two side seals configured to be attached to opposite end portions of the bottom seal and extend forwardly therefrom. The side seals can be shaped and sized to effectively seal openings and/or gaps that may exist between the bottom seal, the deck lip, a shipping vehicle, a dock bumper, and/or the building floor.
1. A dock leveler sealing system for use with a dock leveler having a deck and an extendable lip, the sealing system comprising:
a bottom seal configured to be attached to an underside portion of the deck and move up and down therewith; and
a side seal configured to be attached to the bottom seal and extend forwardly therefrom, wherein the side seal includes:
a lower surface portion;
a forward surface portion configured to be positioned beneath the deck lip and face away from the bottom seal, the forward surface portion extending between the lower surface portion and a first upper surface portion; and
an aft surface portion configured to be attached to the bottom seal, the aft surface portion extending between the lower surface portion and a second upper surface portion that is vertically offset from the first upper surface portion.
2. The dock leveler sealing system of claim 1 wherein the first upper surface portion is vertically offset from the lower surface portion by a first height, and wherein the second upper surface portion is vertically offset from the lower surface portion by a second height that is less than the first height.
3. The dock leveler sealing system of claim 1 wherein the bottom seal has a proximal edge portion configured to be attached to the underside portion of the deck and a distal edge portion configured to hang pendent therefrom, wherein the lower surface portion of the side seal is configured to be positioned adjacent the distal edge portion and the second upper surface portion of the side seal is configured to be positioned adjacent the proximal edge portion.
4. The dock leveler sealing system of claim 1 wherein the first upper surface portion is spaced apart from the second upper surface portion by a gap therebetween.
5. The dock leveler sealing system of claim 1 wherein the side seal includes:
a forward finger bounded by at least a portion of the forward surface portion and the first upper surface portion; and
an aft finger spaced apart from the forward finger by a gap therebetween, wherein the aft finger is bounded by at least a portion of the aft surface portion and the second upper surface portion.
6. The dock leveler sealing system of claim 1 wherein the side seal is a first side seal configured to be attached toward a first end portion of the bottom seal, wherein the sealing system further comprises a second side seal configured to be attached toward a second end portion of the bottom seal, and wherein the first and second side seals are at least approximately identical.
7. The dock leveler sealing system of claim 1 wherein the side seal includes a side surface extending between the aft surface portion and the forward surface portion, and wherein the side seal further comprises a replaceable cover realeasably attached to the side surface.
8. The dock leveler sealing system of claim 1 wherein the first upper surface portion is spaced apart from the second upper surface portion by a gap therebetween, and wherein the side seal further comprises a replaceable cover realeasably disposed over the gap.
9. The dock leveler sealing system of claim 1 wherein the side seal includes a first side surface extending between the aft surface portion and the forward surface portion and an opposite second side surface extending between the aft surface portion and the forward surface portion, and wherein the first side surface is spaced apart from the second side surface by a side seal width of from about 4 inches to about 16 inches.
10. The dock leveler sealing system of claim 1 wherein the side seal is comprised of a resilient core material covered by a durable cloth.
11. The dock leveler sealing system of claim 1 , further comprising a bumper seal configured to be attached to an upper portion of a dock bumper, wherein the side seal is configured to contact the bumper seal when the dock leveler is in a lowered position.
12. The dock leveler of claim 1 , further comprising a beveled surface extending at an angle between the forward surface portion and the first upper surface portion.
13. The dock leveler sealing system of claim 1 wherein the first upper surface portion and the second upper surface portion are at least approximately parallel to each other.
