Steering System For Crane

A steering system for controlling the steering mode of a crane comprising:

• a crane structure having a first front wheel proximate a front portion of a first side of the crane structure, a second front wheel proximate a front portion of a second side of the crane structure, a first rear wheel proximate a rear portion of the first side, and a second rear wheel proximate a rear portion on the second side;
• a user interface for selecting a steering mode;
• and,
• a controller communicatively coupled to the user interface, the controller configured to monitor the position of the first and second front wheels and the first and second rear wheels, and to control movement of the first and second front wheels and the first and second rear wheels in response to a selected steering mode, the controller further configured to monitor an operating parameter of the crane.

A steering system for controlling the steering mode of a boat lifting apparatus comprising:

• a frame structure having a first front wheel proximate a front portion of a first side of the frame structure, a second front wheel proximate a front portion of a second side of the frame structure, a first rear wheel proximate a rear portion of the first side, and a second rear wheel proximate a rear portion on the second side;
• a user interface for selecting a steering mode;
• and,
• a controller communicatively coupled to the user interface, the controller configured to control movement of the first and second front wheels and the first and second rear wheels in response to a selected steering mode, where in response to selection of a carousel steering mode, the controller is configured to move the first front wheel and the second rear wheel in a counterclockwise direction and to move the second front wheel and the first rear wheel in the clockwise direction to place each wheel in the programmed position for the carousel steering mode.
