A seal for a dock levelling system including a movable ramp arranged within a recess. The seal is for sealing a gap between a side of the movable ramp and a wall of the recess, and including a flexible strip formed of a flexible material, and on each longitudinal edge of the flexible strip, an attachment strip for attaching the flexible strip to the side of the movable ramp. The seal is arranged so that when the attachment strips are attached adjacently to each other to the side of the movable ramp, the material of the flexible strip between the attachment strips forms a closed loop extending out from the side of the movable ramp to the wall of the recess, to seal the gap between the side of the movable ramp and the wall of the recess.

The present disclosure describes a unique pet ramp, which allows aging or infirmed pets, of various sizes to traverse an obstacle in a safe and controlled manner. The pet ramp includes a ramp base assembly and one or more rail assemblies. A support assembly may also be provided. The base assembly including a plurality of base cleats.

Provided in this disclosure is an actuatable quick changeover device stand for placing and removing a load from a bed of a vehicle. The device stand includes a traversable base having a planar surface for supporting the load and configured for rearward displacement off the open gate end of the bed. First and second support assemblies are mounted to the traversable base and configured to extend onto an underlying surface behind the open gate end of the bed to support the load. A pivoting support assembly is mounted to the traversable base and configured for pivoting into contact with the bed to support the load during the rearward displacement. An actuator is connected to the pivoting support assembly for inclining the pivoting support assembly toward the bed at a predetermined tilt angle with respect to the planar surface of the traversable base.
