An apparatus for the support and the controlled advancement of a sheet in a bending machine for forming a cylindrical or conical structure, in particular of a truncated cone structure, comprises a base structural frame adapted to be positioned upstream of said bending machine, with respect to an advancement direction of the sheet, a plurality of conveying modules which can be mounted, removable, on the structural frame so as to generate a plan of modular support and advancement which can be configured geometrically according to the shape and dimensions of the sheet to be produced; the modular support and advancement plane is geometrically configured to keep the sheet metal part supported by the plane in a flat condition; an lifting and tilting device configured to vary the position of the structural frame, supporting the conveying modules, from a horizontal lying position to an inclined lying position in which the support and advancement plane is inclined downwards towards the bending machine; repositioning and position correcting members configured to orient and arrange the sheet in a correct position before starting a bending cycle and configured to correct, during the bending cycle, the position of the sheet to impose it a predetermined advancement trajectory towards and through the bending machine. The relative method is also envisaged.

A conveying apparatus for conveying laden or unladen load carriers, having a first conveying unit and a second conveying unit, wherein each conveying unit can be displaced on ground-level rollers and the first and the second conveying units can be moved relative to one another and independently of one another. A device is provided for determining the position and the location of the first conveying unit relative to the second conveying unit, the device having a camera, which is arranged on the first conveying unit, and having a feature arranged on the second conveying unit, or a combination of features arranged on the second conveying unit, wherein the feature or the combination of features has an extent in the direction of travel and an extent perpendicular to the direction of travel, wherein the extents can be sensed by the camera. A conveying unit for a conveying apparatus is also provided.

A device or system for transporting an object to be transported, such as a heavy roof mountable HVAC unit, via inexpensive mechanical lift features that may be easily assembled onto system components that include mobile features, such as wheels. The device and system may include three or more wheeled attachment features that are selectively attachable to the object to the transported. Each wheeled attachment feature may include a selectively variable height mechanism, such as a jack; a securing mechanism for securing each wheeled attachment feature to the object to be transported, the securing mechanism including, for example, a mounting plate and a securing tab for holding the wheeled attachment feature to the object; and a wheel coupled, for example, via an upright inner sleeve, to the variable height mechanism.

Systems and methods for unloading a cargo object from the pickup truck bed. Exemplary methods include installing a cargo unloading system in the pickup truck bed, loading the cargo object into the pickup truck bed, sliding the cargo object along the carrying surface of the pickup truck bed toward a front section of the pickup truck bed, creating a rearward force on the cargo object with the unloading system, thereby causing the cargo object to slide along the carrying surface of the pickup truck bed toward the rear section of the pickup truck bed, and unloading the cargo object from the pickup truck bed by removing the cargo object from the carrying surface of the pickup truck bed.
