  • Cable reel trailer
    Patent number: 11052809
    Abstract: The present invention discloses various aspects of 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. The inclusion of a pivotally connected tongue that is pivotally connected to the main frame of the trailer 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.
