An electric chuck system for a tongs car, which is connected to an electric wire connected to the positive terminal of the electric car chuck, a -pole electric wire is grounded to the main body of the electric chuck, and a negative terminal of the power supply of the tongs car is grounded to the body of the tongs car.

도 1을 참조하면, 종래의 집게차용 전자척 시스템은 집게차 전원(1)의 +극에 전자척(10)의 리드박스(11)에서 나오는 +극 전선(13)이 연결되고, 집게차 전원(1)의 -극에 전자척(10)의 리드박스(11)에서 나오는 -극 전선(15)이 연결되어 있으며, 상기 +극 전선(13)과 -극 전선(15)이 피복선(17)에 의해 커버되어 있어, 집게차의 붐대(3) 단부에 전자척(10)을 매달아 작업을 수행할 때, 집게차의 회전운동 및 붐대의 링크 운동에 의해 +극 전선(13)과 -극 전선(15)이 꼬이거나 마찰됨으로서, +극 전선(13)과 -극 전선(15)의 절연선이 벗겨져 합선될 수 있는 문제점이 있었다.Referring to FIG. 1, in the conventional electronic chuck system for a tongs truck, a + pole wire 13 from the lead box 11 of the electric chuck 10 is connected to a + pole of a tongs power supply 1, and a tongs car power supply 1 Is connected to the -pole wire 15 from the lead box 11 of the electronic chuck 10, and the + pole wire 13 and the -pole wire 15 are covered by the sheath line 17. When the electric chuck 10 is suspended by the boom stand 3 end of the tong truck, the + pole wire 13 and the-pole wire 15 are connected by the rotary movement of the tong car and the link movement of the boom. By twisting or rubbing, there is a problem that the insulation wires of the + pole wire 13 and the-pole wire 15 may be peeled off and short-circuited.
