Provided is a system and method for positioning a load including an apparatus having a plurality of columns. Each column has a first support and a motor adapted to move the first support along an axis of the column. A second support is connected to at least two of the first supports and a track member for receiving a portion of a vehicle is connected to the second support. Load and position sensors are coupled to the apparatus for transmitting load and position signals. A controller is in communication with the columns and receives the load and position signals to compare the load and position signals to generate at least one control signal that is sent to at least one of said motors for controlling the position of at least one of said first supports.

A lift for relocating a toolbox includes a base plate attached to a truck bed having a lifting mechanism mounted thereon. The lifting mechanism is attached to a rectangular support frame that is dimensioned and configured to cradle and grip the bottom wall of a given toolbox. When actuated, the lifting mechanism rotates within a ninety-degree range to move the toolbox from a lowered position, adjacent and parallel to the truck cab, to a raised position, adjacent and parallel to the bed sidewall.

Vessel transfer systems are provide herein. The systems include bogies, including a pivoting bogie and a rack and pinion bogie, as well as associated cradles, carriages, and power and control units. The pivoting bogie includes a first side frame, a second side frame, at least one wheel coupled with each of the first and second side frames, and a lift member coupled with each of the first and second side frames. The lift member is pivotably coupled to the first side frame. The rack and pinion bogie includes a frame and pinion gears coupled with the frame. The pinion gears can be selectively coupled with a gear rack, such as at a shipyard. Also provided herein are methods of use of one or both of the bogies and associated equipment, such as for moving vessels within a shipyard.
