It is observed that the task of installing cable or internet wires from one building to another is very tedious, less precise, and also a bit risky. Usually, this task is carried out using a simple rope and ball mechanism i.e at one end of the rope is a ball tied and at the other end is the wire to be transported. Now the ball is thrown to the destination with the rope equal to the distance between two buildings and as the ball reaches the destination the rope is pulled along the wire. Thus we can see this entire process is very long and less precise. To make this task simple and overcome all these problems we have proposed a mechanical device called as ‘LDOT Gun’ i.e Larger Distances Objects Transporting Gun which simply works on the principle of air pressure i.e pressurized air filled in the gun when released helps the object reach up to its destination with the help of ball and rope attached at the nose of the gun. This gun not only transports wires from one elevation to another but also transports other heavy objects. Also, this device is easy to use and quite affordable making the task precise and eradicating all the risk factors.
