A pull-behind carriage has an auxiliary wheel mounted on a reconfigurable drawbar. When the pull-behind carriage is converted to a push carriage, the drawbar is folded so that the auxiliary wheel is positioned on the ground to act as an extra, supporting wheel. Joints in the drawbar are palm operated and can be rotated without continuing to hold the joint. The drawbar may also serve to move the axle of the main wheels backwards when the carriage is converted from the pull-behind mode to the push mode.

A motorized wheelbarrow assembly for includes a wheelbarrow that has a pair of handles and a wheel rotatably coupled between the pair of handles. The wheel may roll along a support surface. A drive unit is coupled to the wheelbarrow. The drive unit is in mechanical communication with the wheel. The drive unit selectively rotates the wheel to urge the wheelbarrow along the support surface.

A temporarily attachable sled device for human-powered household vehicles includes a main body and at least one front end chock assembly and at least one rear end chock assembly. The main body is formed of a substantially waterproof sheet, with substantially at least the lower face of the sheet formed as a low friction surface. The at least one front end chock assembly and the at least one rear end chock assembly extending from the upper surface of the main body in use. The main body and the chock assemblies are sized and shaped so that a household vehicle can be positioned on the upper surface of the main body and prevented from riding up and over the chock assemblies. The main body includes ridges along and extending upwards from each side of the main body, the ridges extending substantially the length of the sides.

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.
