A mobile welding cart designed to incorporate and integrate components to lift the welding unit, and to provide power for accessory components and tools, is provided. The cart comprises a base frame, supported by four wheels, connected to a lifting platform by way of a scissor lift mechanism. The lifting platform is operable between an expanded position and a retracted position. A storage compartment is located on the lifting platform and a welder is located on top of the storage compartment. The cart also includes a power box connected directly to the rear of the storage compartment that is designed to receive power from a single extension cord connected to the input power of choice. This power box may provide power to all required components and may be equipped with components to convert the power emanating from a power supply in the power box.

An assist control device controls an electric motor assisting traveling of a mobile object. The assist control device includes an operating switch and a control part. The operating switch is configured to be turned on when operated by a user. The operating switch is configured to be turned off when released from being operated by the user. The control part controls the electric motor to output an assist force when the operating switch is turned on.

An autonomously traveling cart system includes a mover, a memory, a position detector, and a processor. The mover moves a cart main body. The memory stores map data indicating an autonomously traveling cart storage space installed in an area where the cart main body is movable. The position detector detects a position of the cart main body. The processor designs a moving route from the position of the cart main body which the position detector detects toward the autonomously traveling cart storage space indicated by the map data, and allows the cart main body to move toward the autonomously traveling cart storage space by the mover.

A method of facilitating production of a structure at a construction site, the method including the steps of: a) obtaining a mobile apparatus having: a frame; first and second wheels and a steerable third wheel spaced in a fore and aft direction from the first and second wheels and laterally between the first and second wheels; and a platform on the frame defining a first upwardly facing surface that is spaced at least 20″ above the subjacent surface; b) placing at least one building component in a transporting position on the first upwardly facing surface; c) advancing the mobile apparatus from the first location to a second location at or adjacent the construction site; and d) separating the at least one building component from the transporting position at the second location.

A concrete/cement resurfacing machine integrates a dust collection subsystem and an overlay mixing/distribution subsystem, enabling a single operator to steer the machine to a desired floor location and deposit mixed, cementitious overlay material. The combination of dust collection and overlay mixing saves considerable time and achieves improved results, eliminating the need for separate vacuum machines while reducing the risk that dust will be released as bags of dry ingredients are added to the mixing tank. A single propane engine powers a hydraulic pump, with fluid being routed to three separate hydraulic motors with associated control valves to provide for forward/reverse locomotion, bidirectional paddle mixing, and vacuum generation. The dust collection system is preferably a two-stage system including a vacuum collection tank and a HEPA filter.

A portable beach cooler is capable of reducing the temperature of stored items. A main cooling body opens to reveal an ice tray. The ice tray may be connected to a lifting mechanism that allows the ice tray to rise for convenient user access to ice. The lid of the cooling body may have several cupholders traversing through the lid, providing direct access to ice for contained beverages. A cupholder adapter may support beverages atop the lid or may be inverted atop a beverage contained within the cupholder to provide direct beverage access to ice while simultaneously preventing cold air from escaping. A set of tracked wheels is connected to a motorized frame capable of supporting the cooling body. The apparatus may further be equipped with cameras to allow for automatic maneuvering of the motorized frame behind a user, as well as a variety of other electronic ports and devices.

A dolly for a water vessel is an apparatus that facilitates the transportation of a water vessel on land. The apparatus serves as a universal attachment for water vessels. The apparatus includes left brace assembly, a right brace assembly, a connector bar, a first roller assembly, and a second roller assembly. The left brace assembly and the right brace assembly attach onto a transom of a water vessel. The left brace assembly and the right brace assembly may be adjusted to accommodate transoms of varying heights. The connector bar mounts the left brace assembly with the right brace assembly, thereby positioning the first roller assembly and the second roller assembly. The first roller assembly and the second roller assembly uplift the water vessel and rolls the water vessel across the ground. The apparatus further includes a cradle mechanism which further supports a paddleboard or a kayak.

An extendable vehicle jack includes a horizontal frame having a rear section with a front section extendable therefrom. Within the front section is a lifting mechanism including a plate that engages the lower surface of the vehicle as it is being raised and lowered. The lifting mechanism includes a hydraulic pump and cylinder that expand and contract a scissors jack. The front section is automatically extended from the rear section with either a hydraulic or pneumatic cylinder. Accordingly, a worker can position the lifting mechanism any desired location beneath the vehicle frame.
