It is used as a method of installing these wires by inserting them into the inner pipe.

However, there was a problem in that the work efficiency was significantly lowered, such as very difficult and taking a lot of work time, because there is no separate equipment for the conventional wiring work for inputting and withdrawing electric wires, so the work is mainly performed manually by a person.

As a prior art disclosed to solve the above problems, in Korean Patent Publication No. 1272228, in the wire pick-up equipment used for carrying wires at a construction site and for picking up work, the wire pick-up equipment consists of an upper plate and a lower plate. a body formed in multiple layers; a handle configured on one side of the body; a seating part formed so that the wire roll can be seated on the body; a through hole penetrating through the upper plate of the body upward and downward; a wire induction part which is formed to protrude upward from the upper plate of the body and fixes the wire strands released from the wire roll seated on the seating part; As it is composed of a wheel that is configured in the lower part of the body and used for moving, it is known that the wire entry equipment can not only quickly store and transport wires, but also can easily carry out wire selection work.
