A cart comprising a support frame having a plurality of wheels, a reel supported by the support frame, and a tool tethered to the support frame.

A transport cart for transporting a ballast block upon a ground surface by a user. The ballast block has a front, rear, top, bottom, and has a plurality of fastening openings on the top. The transport cart has a main frame having a pair of parallel side members, a wheel assembly, a pair of overhead frames attached between the side members, and a cross member attaching the overhead frames. A lifting mechanism is attached to the cross member and includes a lifting arm extending parallel to the side members, and a pair of engagement plates attached to the lifting arm. The engagement plates fasten to the fastening openings on the top of the ballast block. The lifting arm is raised by rotating a handle to raise the block above the ground surface, whereupon the ballast block may be moved along the ground surface using the wheel assembly.

An apparatus for transporting hanging crops comprising a container having an open top and defining an interior compartment extending between first and second sides, a plurality of rigid elongate rods adapted to span between the first and second sides of the container, a plurality of pairs of rod supports secured to the first and second sides of the container proximate to the open top, adapted to removably receive the plurality of rigid elongate rods thereon; and a plurality of rollers secured to a bottom of the container. A method for transporting hanging crops supporting a plurality of crops along each of the plurality of elongate rods, adapted to span between the first and second sides of the container and lowering each of the plurality of elongate rods with the plurality of crops thereon into the interior compartment and suspending each of the plurality of elongate rods from the pairs of rod supports.

A counterbalanced vertical track assembly which may be configured with three types of pulley support assemblies are herein disclosed. The first type of pulley support assembly has a pair of opposed pulley modules having an elongate structural element interposed the two pulley modules which are attached to end plates at both ends of the elongate structural element. The second type of pulley support assembly has a pair of opposed pulley modules which include male end connectors for demountable engagement of the pulley modules with another module of the system with female ends. The third type of pulley support assembly has a pair of opposed pulley modules wherein the modules' pulley brackets are repositionable to varying angular orientations by alternating screw mount positions selected on mount components at opposite ends of an elongate structural element.

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.

A multiple bag hanging cart is described having a plurality of hooks planar with the sidewalls of the cart. Embodiments can include carts retrofitted with hook assemblies as well as the hook assemblies themselves. The hook assemblies can include downwardly or upwardly extending hook prongs over which the handle of a shopping bag is received.

A weight system includes a cart comprising a plurality of wheels and a frame on the plurality of wheels. The frame has a plurality of rails, and a basket is suspended from the plurality of rails of the frame. A weight sensor is coupled at one end to the suspended basket and attached at another end to one of the plurality of rails of the frame from which the basket is suspended. The weight sensor is adapted to detect weight change of the basket when an item is placed into or removed from the basket.

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.
