A supporting structure that supports a heat exchanger having a saddle is provided. The supporting structure includes a first supporting structure for supporting the saddle along one end thereof and a second supporting structure for supporting the saddle along another end thereof. The first supporting structure and the second supporting structure are situated spaced apart from each other by at least a distance enabling passage of a transporter for transporting the heat exchanger.

A multi-directional transport system for transporting a heavy load that includes robotic units that act in synchronization to move a heavy object. The robotic units include an integration of system controls that allow the robotic units to communicate with each other and move in synchronization. The robotic units may be controlled remotely. The robotic units may be battery powered and the driving motor. The robotic unit may have an attachment point for secure attachment to the object.

A puzzle-based storage system to be operated on a floor area, and a method for providing such, comprising a set of separate transportation assemblies placed together in a two-dimensional puzzle-based configuration occupying minimal floor area. Each transportation assembly comprises a rolling arrangement connected to a transportation body for moving the transportation assembly on the floor area, each transportation assembly is carrying and conveying a storage device. The rolling arrangement connected to each transportation body comprises at least four replaceable autonomous rolling devices, where each rolling device comprises a rolling element, driving means, sensors, controller, communication means, and a rechargeable power supply. Charging means providing power to the rechargeable power supply is provided on the floor area where the puzzle-based storage system is operating. Positions of each transportation assembly is controlled by a central controller unit comprising transmitting and receiving means and which is wirelessly connected to at least one of the replaceable autonomous rolling devices of each transportation assembly.

An automatic unloading dolly that automatically unloads pallets therefrom that includes a frame having a loading/unloading side and a pusher side, a conveyor platform that extends between the loading/unloading side and the pusher side, one or more wheels connected to the frame, a multi-bar linkage system mounted to the frame and connected to a pusher that moves along the conveyor platform from the pusher side toward the loading/unloading side between a pusher base position and a pusher triggered position, and a contact arm link connected to the multi-bar linkage system such that movement of the contact arm link relative to the frame from a contact arm link base position to a contact arm link triggered position moves the multi-bar linkage system and the pusher from the pusher base position to the pusher triggered position.

A drum loading and unloading system and method for loading and unloading a drum. The system includes a portable base unit having pedestals for holding a drum at a predetermined position for loading and unloading material from the drum; a pair of pneumatic cylinders attached to the portable base supporting a cross-beam; a pumping piston attached to the cross-beam for pumping material into and out of the drum; and a lifting device attached to the cross-beam for lifting the drum onto the pedestals of the portable base.

A lifting device includes a body or frame, a track, a lifting mechanism having a trolley moveable relative to the track for lifting an object, a main set of wheels coupled to a base portion of the body/frame, a maneuvering set of wheels coupled to the base portion between at least a portion of the main set of wheels and the trolley and vertically offset from the main set of wheels, and at least one arm extending outwardly from the base portion. The vertical offset between the main set and the maneuvering set of wheels forms a two stage lever which improves the mechanical advantage of the lifting device, thereby decreasing the amount of force needed to recline the object being lifted by the lifting device.
