VEKTOR is a hydraulic cart designed for the operations of leaks localisation in underground gas networks, the cart makes in autonomy and safely the vertical drilling of road surfaces avoiding the possibility, always present, to enter in manual contact with high voltage electric cables, situation that can cause severe accidents or the death. VEKTOR is powered by hydraulic power packs and allows to make multiple holes in short time without manual contacts, so without vibrations on operator hands assuring long operations that are prohibited in manual drilling, this eliminates the fatigue and assures intervention speed. Use is simple, the operator simply position the cart on the point to drill, push the penetration lever and the hole will be done automatically without any hand contact, in the holes will successively be inserted the “gas sniffing probe” of the leak detection instrument. On the cart can be installed also the hydraulic core drill AK46 to make multiple holes with diamond core bits on pavements in concrete or stones. The absence of electricity makes it implicitly safe, it can work even under the rain (operation prohibited with electric drills), VEKTOR is a unique tool and cannot miss today in the equipment of modern crews that works in the maintenance of gas networks.
