This invention relates to an apparatus for transporting and dispensing wire or cable. More specifically, it relates to a secondary wire reel that attaches to and is removable from a main reel of wire and cable.
To distribute electricity throughout a building, insulated electrical wires or cables are installed between a power source and a power distribution box and routed to electrical boxes to supply electricity to a device. Often, these electrical wires or cables are routed through multiple conduits throughout the building spanning great distances. As such, installing electrical wires presents both logistical and mechanical challenges. Wires are typically installed in a building by pulling the wire via pulling cables through the building's infrastructure. The wire is spooled off of one or more reel assemblies during the wire pulling process.
Wire is typically transported from a wire manufacturing site to the building construction or installation site on the reel assembly typically made from metal or wood. These reel assemblies can have diameters of up to 48 inches or more, and are capable of carrying thousands of pounds of wire. At the construction site, construction workers are faced with the challenge of spooling the large bulk of wire from the reel assembly during a wire pull. The size and weight of the reels when carrying cable or wire present many problems associated with installation at the installation site. The reel assembly is usually lifted off of the ground and set upon a pair of jack stands, which allows the reel to freely spin during a wire pull. During a wire pull, one end of the wire is attached to a pulling cable. Today, electric-powered machines are used to apply a pulling tension to the pulling cable, thereby spooling the wire off of the reel and through the building's infrastructure.
The use of jack stands to support the reel assembly during a wire pull has a number of significant disadvantages. For example, it requires heavy machinery or multiple personnel to lift a large reel from the ground to the jack stand platform. This use of heavy machinery is both costly and dangerous to construction workers. Also, jack stands are themselves large pieces of equipment. They are difficult to transport, and when installed, they consume a large amount of floor space at a construction site. For smaller construction sites, the jack stand can present significant space challenges during construction. One solution to the above is to deliver the reel and wire to the construction site on a portable jack stand installed on a flat-bed truck. However, this solution also has many disadvantages. First, the jack stands are large and limit the amount of available flat-bed space to transport multiple reels. Second, flat-bed trucks can take up a large amount of space at a construction site when positioned for spooling. Another solution is to use portable jack stands with built-in lifting mechanisms. However, these jack stands require additional equipment, and again, they can take up an inconvenient amount of space at a construction site while still requiring that the reels be lifted off of the ground and placed in a jack stand. Moreover, this solution requires the use of additional pieces of equipment with associated costs and space requirements.
Moreover, many installations require multiple wires to be dispensed and installed together. Traditionally, this requires a reel for each wire and a jack stand for each reel, which further compounds the issues discussed above. One prior solution has included setting up an additional reel that had to be shipped separately on its own packaging to the end user. This solution makes it more difficult to find the space and manpower to place multiple reels in an area to be used. An example of this installation occurs during the installation of a single ground wire, generally a smaller sized wire, alongside of a paralleled reel of wire or other type of wire conductors. Typically the ground wire and paralleled reel of wire are transported on multiple pallets requiring the arrangement of the additional pallet or reel of the ground wire into a designated area for the installation of the paralleled reel of wire.
A prior art solution of dispensing multiple wires, including ground wire, includes incorporating multiple bays in one reel, which each wire spooled into each bay. This solution is susceptible to the faults of the prior art solutions discussed above. Additionally, in some installations, at least one wire may be of a different thickness than the remaining wires. In this situation, for each rotation of the reel, more wire of the smaller diameter is dispensed than of the larger diameter wire often causes twists, kinks, or other issues related to efficiently dispensing a plurality of wires for installation at the same time.
Thus, there is need in the art for a reel system that is compact, easily transportable, and capable of spooling multiple wires while allowing the additional single conductor wire to be packaged, shipped and dispensed separate from the mail reel of wire or cable.
The present disclosure is directed at a system and apparatus for transporting and dispensing wire or cable wound on a reel or spool. The apparatus according to one embodiment is an apparatus for the transportation and dispensing of spooled wire or cable, the apparatus including a payoff reel, a side car reel, and a jack, wherein the jack raises and lowers the side car reel to allow dispensing of the cable. The side car reel and jack are attached to the payoff reel. One advantage of the apparatus is that it incorporates an additional reel of wire to the side of the main reel to allow for easier transport, packaging, and use at the end user jobsite.
