The bed frame then rotates about its pivot point and the entire device is tilted to dump the material onto the ground. In repositioning the device, the bin is pushed forward until the entire device pivots back to a horizontal direction.

Abstract: The Grab and Center Boat Loading System is a centering guide system which helps one person load a boat on a boat trailer with no other person assisting. The system consists of two side mounted, spring loaded, rotating guides and one front mounted fixed standing guide which may be mounted on most boat trailers. Because each side mounted guide is designed to rotate forward and down if struck from the aft or stand and hold if struck from the side direction, this system helps a person safely load even large boats without any assistance. If, while being loaded, the boat rams one of the guides from the aft direction, the guide will rotate forward and down rather than damage the boat or itself. It will then begin to raise back up and begin to center the boat over the trailer. Once both side guides are standing with the boat confined between them, the boater then simply points the bow toward the front mounted guide and drives the boat slowly and safely to the front of the trailer.

The curvature of the mounting arm is such that it slides and pivots within the curved groove of the saddle, allowing the rollers to follow the compound curvature of a boat hull during loading or unloading.

Abstract: A pivoting keel guide for boat trailers which can be used with most boats, can be easily field added to existing trailers, and which will provide excellent centering action for crosswinds when the trailer is submerged.

The guide arm is biased into a raised position using resilient elements such as springs, so that the guide rollers can contact the bottom of the boat while the trailer is submerged. The guide arm pivots along the length of the trailer as the boat settles onto the trailer, exerting a constant centering force.
