Abstract
Seal apparatus for dock levelers are disclosed. An example loading dock includes a dock leveler movable between a standard loading position, a cross-traffic position and a below-deck loading position. The dock leveler has deck and lip movably coupled to the deck. A seal assembly is coupled to the loading dock adjacent a forward edge of the dock leveler. The seal assembly sealingly engages a front surface of a lip of the dock leveler and a rear surface of the lip when the dock leveler is positioned in a cross-traffic position or a below-dock position.
Claims22
A loading dock comprising:
- a dock leveler movable between a standard loading position, a cross-traffic position and a below-deck loading position, the dock leveler having deck and lip movably coupled to the deck;
- and
- a seal assembly coupled to the loading dock adjacent a forward edge of the dock leveler, the seal assembly to sealingly engage a front surface of a lip of the dock leveler and a rear surface of the lip when the dock leveler is positioned in a cross-traffic position or a below-dock position.
A loading dock comprising:
- a deck movable between a raised position, a cross-traffic position, and a lowered position;
- a lip pivotally coupled to the deck and movable between an extended position and a retracted position, the lip defining a lip face and a backside;
- and
- a front seal coupled to the loading dock, the front seal configured to be positionable between the lip face of the lip and a rear edge of a vehicle to sealingly engage the lip face when the lip is in the retracted position and the deck is in at least one of the cross-traffic position or the lowered position.
A seal apparatus for use at a loading dock, the seal apparatus comprising:
- a front seal to be movably coupled to a dock face of a load, the front seal to move relative to the dock face in at least one of a first direction away from the dock face or a second direction towards the dock face;
- and
- a rear seal coupled adjacent the front seal, the front seal and the rear seal to receive a lip of a dock leveler therebetween such that the rear seal engages a backside of the lip and the front seal engages a frontside of the lip.
