An accessory-mounting system having an elongated rail and a rail clamp. The elongated rail has a first channel and a second channel. The rail clamp includes a first lever and a second lever that are pivotally joined such that the rail clamp has a scissor-like configuration. Each of the first lever and the second lever has a tongue for selectively engaging one of the first and second channels of the elongated rail. In addition, the first lever of the rail clamp comprises a first set of spaced apart fingers and the second lever of the rail clamp comprises a second set of spaced apart fingers. The first set of spaced apart fingers and the second set of spaced apart fingers are interlaced. The rail clamp may be joined to the elongated rail at one of a plurality of discrete locations.

A dolly for supporting a tire of a motorcycle or motor scooter off the ground is provided. The dolly comprises: axially aligned wheels supported by a frame which has a frame part forward of the wheels and a frame part behind the wheels, the forward frame part having an open end being such that the motorcycle or motor scooter tire can locate in the open end, at least one tire gripping member on the forward frame part and adapted to wedge the tire when the forward frame part is lifted and release the tire when the forward frame part is lowered, and a wheel on the frame part behind the wheels.

The present disclosure is directed to battery cart for transporting large and heavy electric car batteries. The cart includes a pair of independently movable and positionable cart half assemblies, with each cart half assembly having a pair of battery supports that are slidably positionable and lockable along a center crossbar. Each support includes height adjustable columns. The cart assemblies therefore, are adjustable to support batteries of varying sizes as well as positioning a supported battery to desired height, facilitating repairs to, and transport of, the electric car battery.

Cable protector devices, assemblies, and systems. The cable protection system may include a moveable system with wheels for moving the moveable system across a floor and a cable pusher attached to each of the wheels. Each cable pusher may include a frame with a pair of deflector legs configured to be positioned in front of and behind each wheel in close proximity to the floor. The cable pusher may be magnetically secured to the wheel, and the deflector legs may magnetically connect to the frame. As the wheels spin or rotate, the frame and deflector legs remain stationary, thereby pushing obstacles out of the way.

A hand truck having a plurality of hingeably engaged sides that is expandable from a closed position dimensioned to fit through a standard doorway, to an open position to form a movable platform having a swing out support frame having an upper end hingedly attached to the rear side of the center frame which is movable between an extended position and a stored position. A corresponding sofa dolly and a platform enclosure is also disclosed.

A device or system for transporting an object to be transported, such as a heavy roof mountable HVAC unit, via inexpensive mechanical lift features that may be easily assembled onto system components that include mobile features, such as wheels. The device and system may include three or more wheeled attachment features that are selectively attachable to the object to the transported. Each wheeled attachment feature may include a selectively variable height mechanism, such as a jack; a securing mechanism for securing each wheeled attachment feature to the object to be transported, the securing mechanism including, for example, a mounting plate and a securing tab for holding the wheeled attachment feature to the object; and a wheel coupled, for example, via an upright inner sleeve, to the variable height mechanism.

A pair of dollies for storing and transporting scaffold frames is disclosed. Each dolly is made up of two identical dolly members containing a top plate, bottom plate, two side pates and a front and back plate. Communicating holes are inserted along the length of the top and bottom plates. The side plates of each dolly member has semi-circular cut outs on the top edges which correspond with the holes in the top and bottom plates. The end holes at the front and back of each dolly member have tubes permanently inserted to receive a typical scaffold 8 inch swivel caster wheel with brake. Scaffold frame legs are inserted into the remaining holes in the top and bottom plates of the dollies. The bottom cross member of each scaffold frame sits on the semi-circular cut outs on the top edges of the side plates. This device can be used for storage or transportation of scaffold frames.

Dollies support steered skis of a snowmobile on wheels to enable the snowmobile to be moved along an underlying surface with carbides on the bottom surfaces of the skis free of contact with the underlying surface.

In certain aspects, a roller assembly includes a base structure defining multiple recesses that extend inwardly from a top surface of the base structure, a first wheel, and a second wheel. The multiple recesses are configured such that at least one of the multiple recesses is engageable with an auxiliary component of the load, and the multiple recesses include a central recess positioned at a center of the top surface of the base structure. The first wheel is disposed along a first side of the base structure, and the second wheel is disposed along a second side of the base structure, the second side of the base structure being spaced apart from and parallel to the first side of the base structure.
