A dolly comprising a front segment and a rear segment, each with wheels at both ends thereof, wherein the wheels are movable between lowered and lifted settings, at least two connecting members between the front segment and the rear segment, and at least one towing ring on the front segment.

A specialized dolly is provided that works with a hydraulic floor jack; together the assembly performs the lifting and moving of vehicles with ease and efficiency. The configuration and design of the dolly enables a standard hydraulic floor jack to be positioned within a frame of the dolly in a stationary position. A handle of a hydraulic floor jack can then be used to maneuver the combination dolly/floor jack assembly with ease on the floor of the repair shop. The dolly may be designed and configured to have stationary low resistance front rear wheel assemblies, both of which provide for convenient maneuvering and steering. The dolly's wheel tracks (distance between front wheels) and its wheelbase length (distance between front and rear wheels) allows the dolly to be stable and significantly maneuverable, especially over or around potholes, slopes, and ramps, and also provides greater safety for the operating technician.

A method for reverse maneuvering a flat-towed dinghy attached to a towing vehicle. A carrier includes a platform, two caster wheels, and a drag mechanism. The drag mechanism is configured to present greater resistance to lateral movement than the two caster wheels. When the front tires of a flat-towed dinghy are loaded onto a pair of carriers, the dinghy is maneuvered in reverse without the dinghy front wheels reverting to the maximum turn that is normally caused by the dinghy front wheel steering caster angle. The dinghy rolls onto the carrier when the flat-towed dinghy is moved in the backward direction. A chock or stop device prevents the front tire from rolling off the platform when the flat-towed dinghy is moving in the backward direction. The dinghy rolls off the carrier when the dinghy is moved in the forward direction.

A pallet moving system includes a pallet dolly puller, and a pallet dolly with a guiding structure thereon permitting and facilitating the blind engagement and disengagement of the dolly puller to the pallet. The dolly puller includes caster wheels, a handle, and at least one projecting portion configured to mateably couple with recessed portions on the underside of the pallet dolly in order that the pallet dolly may be moved and readily re-positioned even in confined spaces.

An unmanned underwater vehicle (UUV) transport cart comprising: a wheeled frame including vertical posts, a front end, and a rear end; a UUV cradle adjustably clamped to the vertical posts such that the UUV cradle is vertically adjustable with respect to the frame; a U-shaped handle pivotally attached to the front end of the frame such that the U-shaped handle pivots up and down around a first axis, wherein the U-shaped handle includes a handle spring that acts between the U-shaped handle and the frame so as to bias the U-shaped handle toward an upward orientation; side handles pivotally attached to the UUV cradle such that the side handles pivot up and down around side axes that are perpendicular to the first axis; and a hand brake affixed to the U-shaped handle and configured to provide active brake control of the wheeled frame.

A loading frame includes a rectangular u-shaped frame with an opening at one side, forks extendable and retractable between the closed side and the open side of the U-shaped frame, loading frame wheels on one arm of the U-shaped frame, and a truck interface on the other arm of the U-shaped frame. The loading frame wheels and truck interface support travel of the frame in a direction other than the direction of travel of the forks between the open and closed sides of the U-shaped frame.

The invention provides a motorcycle dolly, the dolly having an elongated surface with a first end and the second end, wherein the surface defines a first section in rotatable or slidable communication with a second section; and a first plurality of wheels proximal to the first end and a second plurality of wheels proximal to the second end.

A vehicle cart assembly includes a cart that has a panel and a plurality of rollers rotatably disposed on the panel. A ramp is hingedly attached to the panel to facilitate a tire of a vehicle to roll onto the cart. A first pressure sensor is integrated into the ramp which is engaged by the tire of the vehicle when the tire of the vehicle rolls onto the ramp. A second pressure sensor is integrated into the panel to be engaged by the tire of the vehicle when the tire of the vehicle rolls onto the panel. A visual alert is removably attached to the panel which is turned on when the first pressure sensor is engaged to alert a driver that the tire of the vehicle has begun rolling onto the ramp. The visual alert is turned off when the second pressure sensor is engaged to alert the driver that the tire has rolled onto the panel thereby alerting the driver to stop the vehicle.

A loading frame includes a rectangular u-shaped frame with an opening at one side, forks extendable and retractable between the closed side and the open side of the U-shaped frame, loading frame wheels on one arm of the U-shaped frame, and a truck interface on the other arm of the U-shaped frame. The loading frame wheels and truck interface support travel of the frame in a direction other than the direction of travel of the forks between the open and closed sides of the U-shaped frame.

A medical device, such as an intra-aortic balloon pump or carrier with an extendable wheel track and handle configured to be removably carried and integrated with a cart. The wheel track is configured to extend upon extension of the handle and to return to its original position upon retraction of the handle.
