A set of two two-wheeled dollies, each of which has a cradle, preferably V-shaped, is configured to support a length of pipe or other elongated construction material. The dolly set consists of a steerable forward dolly, having a steering handle, and a non-steerable rear dolly. The two dollies are deployed in tandem, with the forward dolly supporting the front end of the load, and the rear dolly supporting the load's back end. By turning the handle bar of the forward dolly in a selected direction and applying a force in that direction, the tandem paired dolly set moves the elongated load in the selected direction.

A two-wheeled, axially-expandable cart having an axially-expandable platform that includes a pair of platform members that are moveable axially between a collapsed position where the edges of the platform members are confronting, and an expanded position when the edges are space apart, and a pair of wheels, each wheel connected through an axle to and extending axially from each platform member. The two-wheeled cart provides a method for hauling an insulated cooler, where the cooler is positioned onto the platform assembly with its center of gravity forward of the platform assembly, and with an extending strap member laced through a front handle of the cooler, for raising the front end of the cooler off the ground and pulling the cooler forward, secured to the two-wheeled cart.

Disclosed are various embodiments of a two-wheeled apparatus for transporting commercial appliance units on a rooftop or other location without the use of a crane or helicopter. The two-wheeled apparatus may include a chassis configured to support a load of a commercial appliance unit, the chassis comprising a first telescoping member and a second telescoping member. Further, the chassis may include a first mount positioned at a first end of the chassis and a second mount positioned at a second end of the chassis. A first wheel assembly may be coupled to the first distal end of the chassis by a first fixed axle and a second wheel assembly may be coupled to the second distal end of the chassis by a second fixed axle.

An assistive device for heavy tool operation includes a rectangular frame and four legs extending from the corners of the frame. A tool base can extend through a slot in the frame. The tool base is configured to support a mechanical support arm and tool. A height and horizontal position of the tool base relative to the frame is adjustable. Each leg is connected to a wheel to allow the assistive device to travel with a user. The assistive device can support a majority, if not all, of the weight of an attached heavy tool and mechanical support arm, while allowing the user to operate the tool and adjust its position with minimal applied force.

A collapsible trolley includes a body having a back panel, a shelf panel pivotally attached to a bottom edge of the back panel, a pair of back wing panels pivotally attached one each to opposing side edges of the back panel, a pair of shelf wing panels pivotally attached one each to opposing side edges of the shelf panel and one each to bottom edges of the pair of shelf wing panels. The body is movable between an unfolded use configuration and a folded storage configuration. A latching member is attached to the body and adapted to secure the body in the folded storage configuration. A pair of wheels is attached to the pair of back wing panels by brackets that trap the wheels between vertical abutment portions and the back wing panels, and the back wing panels have arcuate openings that align with the edge rims of the pair of wheels.

Disclosed is a canoe transport dolly having a main truck, a front truck, and a rod connecting the main truck to the front truck. The main truck and the front truck each have a gantry assembly comprising one or more axles in communication with one or more tires, a powerhead assembly, a plurality of threaded rods interconnecting the gantry assembly to the powerhead assembly. A plurality of arms are in rotational communication with the powerhead assembly, each arm having a hooked end extending away from the powerhead assembly. A canopy assembly positioned above the belt assembly for engaging a canoe gunwale, wherein the canopy assembly releasably engages the arms' hooked ends; and a return asset assembly in communication with the arm assembly, the return asset assembly.

A stackable fan includes a base and a cover pivotable secured thereon. One or more fan blades is formed in the cover. The base includes two lower steps extending downwardly therefrom and a spring-biased latch extending upwardly from an upper edge. The cover includes a ledge having an overhanging portion disposed opposite the spring biased latch. The fan may be secured on top of the cover or beneath the base of variously sized storage containers which also includes steps and latches. The fan may be part of a stackable wheeled storage container system.

A range hood support lift for positioning and supporting the weight of range hoods, exhaust vents, microwave ovens, and the like during the installation process. The range hood support lift includes a support section having a plurality of support arms. A base section includes a plurality of legs and a scissor section separates the plurality of legs. In use, the base section adjusts the height of the support section above the base section and the scissor section adjusts the distance between the plurality of legs.

A tamper cart system for transporting a mechanical tamper includes a mechanical tamper. The mechanical tamper has a handle, a body and a compression plate. A cart is provided and the cart is rolled along a support surface. The mechanical tamper is selectively positioned on the cart. Thus, the mechanical tamper is transportable by an individual. A handle is movably coupled to the cart.

The present invention relates to a manually operable carriage and working attachments that may be employed with the carriage. The attachments may include a plow, a logging clamp, or other implements.
