Work wagon for railway track engineering work - has automatic positioning appts. with set of detectors supplying control signals for wheels and endless tracks

摘要

The positioning system is for a work wagon, which allows the wagon to leave the rail tracks automatically and be replaced again after a train has gone by. The operation can also be carried out manually. It is used for engineering work along the railway tracks and can be propelled forward by endless tracks. The wheels can be raised so that the wagon can be mounted onto the railway tracks. The positioning system consists of a number of detectors on the bottom of the wagon. They transmit signals to the control circuit to control the drive to the wheels or tracks. Each detector consists of a switch with a probe arm to actuate the switch when touching the rail.
