     DESCRIPTION OF THE INVENTION 
     There is provided a vehicle hitch-mountable rigid stand for supporting construction equipment during use or transport. The device can be used while attached to the hitch of a vehicle, or can be disconnected and relocated using a set of built-in wheels and support leg. 
     As may be seen in the figures, in a preferred embodiment, the device of the invention consists of, but is not limited to,  7  main components which may be provided as a kit for assembly. The  7  main components are a main support beam  2  attachable to a vehicle hitch by a vehicle hitch connection post  4  at the first end, a first platform  6  connected above the main support beam by a rotating hub and spindle assembly  8 , an optional second platform  10  which doubles as a first platform extension, an adjustable support leg  12  attached in proximity to the first hitch end of the main support beam, telescopic tubing  14  connecting lifting means  16  to the second end of the main support beam, and a wheel and axle assembly  18  attached to the lifting means. The lifting means may be an adjustable jack such as, for example, an hydraulic jack. 
     In an alternate embodiment, the wheel assembly may be connected by an axle linkage to the main support beam. 
     In one embodiment, the main support beam is a hollow metal tube. Means for attaching the support leg are provided near the first end and may comprise a cylinder, bolting means, or clamping means. The support leg may be attached to the main support beam by telescoping tubing. The rear telescopic tubing is provided with a hollow cylinder for receiving the wheel and axle assembly, which may be fixed in a desired vertical position, although other attachment means such as a clamp are also possible. In one embodiment, the desired vertical position of the wheel and axle assembly is achieved through adjustment of the telescopic tubing using the lifting means, allowing the stand to be used with a wide range of vehicle hitch elevations. The use of lifting means such as an adjustable jack also eliminates the need for a user to manually lift the stand into the vehicle hitch, as the adjustable jack may be used to raise the main support beam to the desired elevation for engagement with the vehicle hitch. The rear lifting means and telescopic front leg support are adjustable to select the height of the stand while attached to or independent of a vehicle. 
     In one alternate embodiment shown in  FIGS. 6 and 7 , the stand may be equipped with a coiling frame  22  and coiling guide  24 . In a further embodiment shown in  FIGS. 8 and 9 , the stand may be equipped with generator frame brackets  26  attached to the first platform. 
     The wheel and axle assembly preferably comprises a pair of wheels joined by an axle having a central vertical post for attachment to the telescopic tubing or axle linkage. In one embodiment, the wheel and axle assembly may be rotated within the axle linkage to permit alignment of the axle with the main beam when not in use. In a preferred embodiment, the wheel assembly may be pivoted and stowed under the main support beam towards the front hitch end of the main support beam when not in use. 
     In the preferred embodiment, a rotating hub and spindle assembly connects the first platform to a medial position along the main support beam. In an alternate embodiment, a vertical platform post extends upwardly from a medial position along the main support beam, and a first platform is attached to the top of the platform post. The platform may have dimensions sufficient to support a variety of industry standard construction trades equipment. In a preferred embodiment, 360-degree rotation of the platform is achieved using a rotating hub and spindle which is lockable in numerous positions using a spring bolt latch, according to the user&#39;s needs. In an alternate embodiment, the platform may be rotated 360 degrees and locked into the desired location by means of locking pins and/or locking bolts. 
     The smooth action of the rotating hub and spindle permits efficient, easy use of the stand as a pipe decoiler or electrical wire decoiler whether the stand is attached to a vehicle or being used remotely. 
     Optionally, a second platform is attachable to the first platform and swivels with rotation of the first platform to maintain the second platform in consistent alignment relative to the equipment on the first platform. The second platform may be an oiler platform. 
     A support leg may be provided in proximity to the first end of the main beam to provide support to the stand when it is used apart from a vehicle hitch. The support leg may incorporate adjustment means such as telescopic tubing to permit vertical adjustment to stabilize the stand on the ground, as well as rotational adjustment to align the leg with the main support beam when not in use while the stand is attached to the hitch of a vehicle. 
     In one embodiment, the main support beam and the platform post may be telescopic tubing to allow for selective positioning of the distance of the wheels from the first end of the main beam, and of the height of the platform, respectively. The main beam preferably will be adjustable between approximately 36 and 50 inches, and the platform post preferably will be adjustable between 12 and 18 inches. 
     In an alternate embodiment, the stand may be provided with two or more wheel and axle assemblies comprising two or more pairs of wheels, rather than a wheel and axle assembly and a support leg. The wheel and axle assemblies may pivot, fold or drop down to the ground to permit the stand to be rolled away from or back to the vehicle hitch. 
     According to another alternate embodiment, the platform of the device may be positioned directly on and swivel about the main support beam, or a set of support beams. According to yet another embodiment, the device of the invention may include sliders attachable to the vehicle such that the stand may be slid on the sliders away from the vehicle prior to use. 
     In an alternate embodiment, umbrella mounting means may be provided on the stand. The stand may also be equipped with means for electrical cord storage such as tabs for wrapping cords, and may be equipped with 12 V wiring to permit illumination of a driving light. 
     The stand of the invention may have a handle which is used to assist in moving the apparatus when disconnected from the vehicle. The handle may be inserted into the main beam and may be locked in place using the hitch pin. 
     The device of the present invention may be easily set up or taken down and relocated by a single person, in contrast with existing prior art equipment which requires a minimum of two. One of the advantages of the present invention is the maintenance of access to the tailgate of a truck or the door of a van while the stand is attached to the hitch. 
     A variety of materials may be used in the manufacture of the stand of the present invention, provided such materials are of sufficient strength to support equipment which may weigh more than 300 lbs. 
     In the preferred embodiment, a vehicle hitch connection post extends perpendicularly from the support leg to permit attachment of the stand to a vehicle hitch. The wheel attachment assembly preferably is adjustable to permit raising of the wheels away from the ground or other support surface. In one embodiment, the wheel attachment assembly may allow rotation of the axle into alignment with the main support beam during transportation of the stand. 
     While the present invention is intended primarily for use with construction equipment, unlimited other applications for this device are also possible. 
     The equipment stand of the present invention may include one or more accessories, including a fitting bin, and sets of mounting brackets to accommodate the mounting pattern of a decoiler, generator, or various other equipment. 
     According to an alternate embodiment for use with a pipe threader, the main platform may be provided with an insertion point for the attachment of another platform for use with a pipe vise which could be used while the threader is in use. 
     As many possible embodiments may be made of the invention, it is to be understood that all matter described in this specification or shown in the images is illustrative and not limiting. It will be appreciated by those skilled in the art that other variations of the preferred embodiment may also be practised without departing from the scope of the invention.
