Methods and apparatus improve the panel support rail, tongue, handle and hinge system for hand-trucks, carts and dollies that convert to panel-carts. A panel-cart, typically seen in large building supply stores, is used to carry plywood panels, windows, door and other similar object as well as long lumber, all of which cannot be carry by a standard hand-truck. The conversion efficiency of a hand-truck to a panel-cart is improved and the user complexity reduced, partially by attaching parts with hinges that were previously separate components, further by using the handle as a primary or secondary support rail when placed in the extended position via hinges or fixed receivers.

A tool for removing a stuck bit of a drilling device from the drilling medium in which it was being drilled is provided. The system generally comprises a frame, a hydraulic lift operably connected to the frame, and a lifting platform. Operating the hydraulic lifting device may cause a strut to move in a linear direction, which may cause the carriage to move in a linear direction. By moving the strut in linear direction such that the carriage extends beyond the length of the drilling device, the carriage may contact the drilling medium, which may cause a lifting force to be applied to the drilling device. A user may then use the carriage to move the drilling device to a new location.

A foldable or collapsible cart can be oriented in several different configurations to accommodate different loads and transport requirements. In one configuration, the cart may be folded for direct load the back of a vehicle. In another configuration, the cart can operate in lowboy or dolly mode. In another configuration the cart may be used as a hand truck.

A luggage article comprising a body including a top face, a bottom face, an a plurality of side faces. A first pair of wheels is disposed at the bottom face of the body. A handle has a first operative orientation wherein the handle is disposed within the body and a second operative orientation wherein the handle extracted from the body. A central wheel is functionally associated with the handle, such that in the first operative orientation of the handle, the central wheel is retracted and disposed in or adjacent a face of the body, and in the second operative orientation the central wheel is extracted and extends outwardly from the body.

Embodiments of a cart for transporting equipment are provided. The cart includes a support, a frame, and legs. The support is configured to hold the equipment. The legs are connected to the support via a first hinge joint. The legs rotate about the first hinge joint between a first leg position and a second leg position. The support is connected to the frame via a second hinge joint. The support rotates about the second hinge joint between a first support position and a second support position. The cart has a first configuration in which the at least one leg is in the first leg position and the support is in the first support position. The cart also has a second configuration in which the at least one leg is in the second leg position and the support is in the second support position.

A wheelbarrow conversion assembly for facilitating a wheelbarrow to be rolled without lifting the wheelbarrow includes a wheelbarrow that has a bucket and a pair of support legs. A bracket is removably coupled to the wheelbarrow and the bracket is positioned on each of the support legs. A pair of rollers is each of the rollers is rotatably coupled to the bracket to roll along a support surface. Each of the rollers supports weight of the wheelbarrow to facilitate the wheelbarrow to be rolled without lifting the wheelbarrow. In this way the rollers facilitate a physically disabled user to roll the wheelbarrow along the ground.

Hand trucks having a powered lifting assembly are disclosed. In certain aspects, hand trucks having a motor assembly and a battery pack mount arranged to removably receive a battery pack arranged for a portable tool are disclosed. Hand trucks having a pivoting rearward support are also disclosed, with particular arrangements advantageously pivoting the rearward support upwardly as it is configured into the retracted configuration so as to lift wheels of the rearward support above other wheels of the hand truck.

A hand-truck frame system includes a main frame, a bed frame, and pair of multi-wheel assembles coupled to the main frame and rotatable to provide improved climbing capabilities over certain terrain, such as stairs. The multi-wheel assemblies can have four wheels radially mounted about respective hubs of the first and second multi-wheel assemblies.

The present invention relates to a foldable tricycle, operable between a first mode of operation steerable by a tricycle rider, and a second mode of operation steerable by an attendant pushing the tricycle. The tricycle comprising: a pair of rear wheels; a foldable seat comprising a chair and a back support, for accommodating said tricycle rider; a foldable arm rest, connected to said foldable seat; a parental handle, for steering said tricycle by said attendant pushing the tricycle; a main frame, configured to rotatably hold said rear support, to support said foldable seat, to rotatably support said rider handle, to rotatably support said fork; and a latching mechanism, capable of locking and unlocking the rotatable movement, of the rear support, in relations to the main frame.
