The present invention relates to cable reel trailers, methods of manufacturing same, and methods of using same. More particularly, the invention relates to a cable reel trailer that uses an automotive force from a vehicle, whether it be a tractor, a truck or any other type of transport vehicle as the power source to lift the cable reel onto the cable reel trailer.
Conventional cable reel trailers are well known in the art, including one of the most common types of hydraulic lifting trailers. that includes a hydraulic motor. This requires a considerable amount of machinery and battery power, which is undesirable to the industry. It would be desirable to provide a vehicle for transporting heavy cable reel loads over roads to transport a cable reel to the construction site, especially a new type of trailer that does not require its own power supply.
In that regard, the present invention provides a new and improved cable reel trailer for transporting cable reels without needing any additional equipment to raise and lower the cable reel during loading and unloading in a very efficient manner. Furthermore, the present invention is very simple and economical while distributing the weight safely over the axle of the trailer. The load is secured easily and inexpensively, with total safety in mind.
U.S. Pat. No. 1,839,320, issued Jan. 5, 1932 to E. E. Kellems discloses a trailer which is adapted to be used in connection with the loading, transportation and unloading of cable reels, including the use of a collapsible trailer, including a main frame cable reel on wheels where it may be rotated to load or unload cable reels.
U.S. Pat. No. 2,650,730, issued Sep. 1, 1953 to Leon M. Rohm discloses a trailer to carry heavy loads, usable for transporting boats, tanks, and other cumbrous objects.
U.S. Pat. No. 3,690,491, issued Sep. 12, 1972 to Cornelius Butler Jr. discloses a cable reel trailer with a y-shaped main frame pivotably attached to a towing vehicle.
U.S. Pat. No. 3,990,650, issued Nov. 9, 1976 to Joseph C. Devine discloses a loadable trailer for the transportation of reels.
U.S. Pat. No. 4,013,184, issued Mar. 22, 1977 to James H. Lacy discloses a trailer with a pivoted support frame which receives and supports a large refuse container pulled into place on the support frame by means of a lifting frame operated by a hydraulic cylinder.
U.S. Pat. No. 4,701,098, issued Oct. 20, 1987 to Joseph W. Bills, et al. discloses a cable reel handling and transportation trailer with hydraulically operated leveling arms on each side of the trailer to engage a spindle reel assembly and roll it forward.
U.S. Pat. No. 4,762,291, issued Aug. 9, 1988 to Charles J. Sauber discloses a self-loading trailer with an arched carrying cable reel able to accommodate a cable reel and side wall to laterally support the reel and with a hydraulically driven set of maneuvering arms for self-loading.
U.S. Patent Application Publication No. 2015/0166297, published Jun. 18, 2015, inventor Noel C. Smith, et al. discloses a trailer for lifting and transporting cable reels with a pair of substantially perpendicular cantilevers, and a latch assembly.
However, practitioners of those inventions have become aware of certain problems which are presented by those prior art inventions. One particular problem that has plagued users has been that the hydraulic and electrical motors common in the prior art break down and cause problems.
In review of the above-noted desires of the industry, the present invention provides various aspects, including a cable reel trailer that uses the automotive force of a tractor or truck used to transport the trailer, a method of making same, and a method of using. This includes a pivotally connected tongue that is pivotally connected to the main frame of the trailer. This overcomes many of the aforementioned problems with the prior art because there is no motor or hydraulic system necessary for lifting the cable reel securely on to the trailer.
In accordance with the present invention, the towing automotive force, such as a truck, tractor or any other hauling vehicle, provides all the power for lifting the cable reel, rather than requiring a separate power source on the trailer for doing the heavy lifting. By locking up the wheel on the trailer with a wheel stop, the forward movement provided by a towing truck can concentrate on lifting the cable reel instead of moving the trailer forward. This means that no separate on-board power is needed for lifting the cable reel.
My unique cantilever design pulls the weight of the cable reel over the axle. By utilizing a pivot point on a main frame, a 90 degree loading position is made possible. As my main frame pivots and then locks down onto the trailer tongue, once the cable reel has been lifted and brought it into position over the axle, the main frame can be locked down by a cotter pin so that the trailer can be safely transported to a job site. In addition, the cable reel spindle axle can easily be locked down and secured in place to prevent movement during transportation. This means that there is no possibility of a load shift during transportation. As anyone who drives a tractor trailer attached to a trailer knows, load shifting can be the most dangerous part of their job.
Due to the fact that the present trailer tongue stays fairly level, it is much safer to load a cable reel because the center of gravity is much lower than those shown in the prior art. During the use of my novel cable reel trailer, the operation is much smoother and much safer than prior art inventions as the wheels are stopped and the tractor/trailer being used to pull the main frame into position provides motion that is steady and sure. Upon careful review of the prior art, my design is much simpler, more effective, and safer. One of the true advantages of the present invention is that I have eliminated many components, lowered manufacturing costs, and therefore a cable reel trailer product that is much more economical for buyers.
Although the invention will be described by way of examples hereinbelow for specific aspects having certain features, it must also be realized that minor modifications that do not require undo experimentation on the part of the practitioner are covered within the scope and breadth of this invention. Additional advantages and other novel features of the present invention will be set forth in the description that follows and in particular will be apparent to those skilled in the art upon examination or may be learned within the practice of the invention. Therefore, the invention is capable of many other different aspects and its details are capable of modifications of various aspects which will be obvious to those of ordinary skill in the art all without departing from the spirit of the present invention. Accordingly, the rest of the description will be regarded as illustrative rather than restrictive.
For a further understanding of the nature and advantages of the expected scope and various aspects of the present invention, reference shall be made to the following detailed description, and when taken in conjunction with the accompanying drawings, in which like parts are given the same reference numerals, and wherein;
In accordance with the present invention a new, useful and non-obvious design for a cable reel trailer, a method of making same, and method of using same is disclosed herein. Many of the shortcomings of prior art inventions have been overcome and a cable reel trailer is disclosed that is safer, simpler to manufacture, and is a non-auxiliary powered application. The main frame of my cable reel trailer stays substantially level which is much safer than prior art inventions because the center of gravity is much lower. The cantilever design easily pulls the weight of the cable reel load directly over the axle of the present cable reel trailer. As the tongue of the trailer is attached to a truck, tractor, or some other conventionally available automotive hauling force, solid control over the movement of the cable reel being loaded is achieved. This turns an inherently dangerous operation into one that is much safer, without the use of any additional motive equipment.
