Title: (EN) Power supply means for electrically operated apparatuses and a switch for the power supply means
Abstract: front page image
(EN)

A trolley-type power supply means and a turntable switch for moving apparatuses such as mining equipment. The switch is provided with two coupling portions installed in parallel with each other and reversely symmetrical with respect to a turning axis. By using coupling portions, a trolley can be turned in a desired direction or shunted from the trolley track to allow another trolley to pass by.
