Abstract: To provide safe operation for unmanned operation of a guiding wire controd vehicle also at higher speeds of about 10 km/h the vehicle comprises a contact feeler mounted on a safety cart, which contact feeler is located ahead of the face surface of the vehicle by a distance exceeding the braking distance thereof. Upon contacting an obstacle the contact feeler triggers a retracting means which retracts the safety cart against the face area of the vehicle triggering at the same time the braking operation thereof. Accordingly, the vehicle can be brought to a full stop without injuring or damaging as well as bodily contacting the obstacle.
