Crossbow Crank Cocking System

We find improvements on existing equipment used in shooting and hunting. I recently found one with a crossbow.

By Norman Johnson

While observing a number of different crossbows being cocked, I could clearly see a need for a better way this could be accomplished. Cocking a 150-175 pound crossbow via direct pull, with both hands, requires considerable strength. The next easiest method is performed by means of a rope cocking aid utilizing a long cord with T-handles on each end fitted to a pair of pulleys that doubled back to the bow frame to reduce pull weight by 50 percent. Though substantially easier, this too can be quite difficult for the aging or incapacitated hunter who really needs help.

As alternatives for easier crossbow cocking, there are various methods of cranking the bow by means of a pulley and hand crank. Most of these are quite effective but not totally uncomplicated to operate and most are noisy out in the woods. They are usually set up to work on one style of crossbow only. There also are specialized cocking systems using gas cylinders and electrical devices rigged to individual crossbows that can be quite expensive.

This was sufficient to inspire the design of a universal crank-cocking system that could be adapted to a number of different crossbows, one that is safe, quiet and easy to carry and attach.

  1. I did hard research to know difference between Rope Cocking Device Vs Crank Cocking Devices. Crank device which appears as a small winch mounting on a crossbow’s stock. This device requires you to wind a crank handle in order for you to cock your crossbow. Before getting this device, it is important for you to determine if this can offer you ultimate satisfaction when using it for crossbow hunting. One of the major advantages of crank cocking device is that you will never have a hard time drawing it back. It is also a major help in your attempt to put the string at the center of the trigger so you can shoot accurately. But the expensiveness of this device is one of its major drawbacks.

    The second type of cocking device is the rope cocking device. This is less expensive than the crank type so it is no longer surprising why a lot of people prefer to use it. You can get it at around twenty-five to forty dollars. Attached in the pull rope of this device are two string clips and handles. It also comes with a pulley system designed to improve its mechanical advantage. The pulley system also allows you to use only half of the strength needed in cocking the crossbow. The device also works in centering your string and this is a major help in improving the accuracy of all your shots. But it is still best for you to put a mark on the bow string’s center to ensure that the process of releasing the arrow produces even force. You can also prepare your next shot within just thirty seconds with the help of this device.
