加拿大贾维斯·克拉克公司近几年生产一种交流供电的架线集电器,称为“移动插头”(The TravellingPlug)。主要与装运卸设备和液压凿岩台车配套使用。“移动插头”有点像车间里起重用的天车,它跟着行走设备一起移动。长1524毫米,高305毫米。有四对滚轮承受全部重量并在一条倒“T”字型的梁上行走,在梁的下面和两侧也有滚轮以保持行走平稳。在这倒“T”字梁的两侧各有两条带凹槽的导线(其中一条作为地线)。倒“T”字梁及四条导线
In recent years, Jarvis Clarke, Inc. of Canada has produced a AC-powered overhead current collector called “The Traveling Plug.” Mainly with the loading and unloading equipment and hydraulic rock drill supporting the use of vehicles. The “moving plug” is a bit like the lifting crane in the workshop, which moves with the walking equipment. Length 1524 mm, height 305 mm. Four pairs of rollers take full weight and walk on a beam of inverted “T” shape with rollers on the underside and on both sides of the beam to keep walking steady. There are two grooved conductors (one of which serves as ground) on each side of the inverted “T” beam. Pour the “T” beam and the four wires
