<p>PURPOSE:To prevent carrying equipment equipped with a propulsion device from abnormally approaching or coming into collision with another carrying equipment by dividing the carrying route of the equipment into a plurality of controlled sections and respectively installing a controller which adjusts the propulsion of the carrying equipment in one section from the ground to each section, and then, operating a feeding switchgear by means of a collision preventing logic circuit. CONSTITUTION:A plurality of carrying trucks 5 respectively provided with reaction plates 4 are mounted on rails 1. The route of the trucks 5 is divided into multiple sections (controlled sections) 7a-7n based on reception loop antennas 6 and switches So and S1 are connected to a collision preventing logic circuit (logic K) 13 in each section. Therefore, when one truck 5 exists in one section 7b and no truck exists in the preceding section 7c, the switch S0 is actuated by the logic K of the circuit 13 and a high propulsion is given to the truck 5. When one truck 5 exists in the section 7c also, a low-speed propulsion is given to the reaction plate 4 of the truck 5 in the section 7b so as to prevent the truck 5 in the section 7b from abnormally approaching or coming into collision with the truck 5 in the section 7c.</p> |
