Tuneladora Lovat RME 167 DS para venda em leilão

drilling capacity 4255 mm; max. speed/torque 3,9 rpm; total rated power 1440 kW; double shield design allowing to dig in both directions an erect segments in line at the same time; rotating cutting head powerd by 4 water-cooled eletric motors cap. 262 kW each with a total power of 1048 kW on the cutting head; fitted with 5 independently operating injection ports on the cutting head used for the injection of foam and bentonite; 4 spokes on the cutting head for mounting cutting teaths and disc cutters; including all documentation and well as a large number of accessories; total machine lenght aproximately 107 meters; total weight aproximately 234 tons; machine workflow explanation= The primary conveyor belt and the drive belts are used to carry the cut rock (debris) from the head of cut to the accumulation system; which is deposited in three cars used to exit the tunnel; The main bearing is a triple-roller type with a pressurized lubrication system and a joint rotating fluid; A drill probe port through the motor plate is parallel to the axis of the tunnel; The cutting head is pushed by a shield (primary shield); which in turn can be propelled by the secondary shield; The secondary shield is reinforced in such a way that it does not need of its propulsion cylinders to maintain its position; The primary shield can push against the secondary shield to dig with the cutting head; With the extraction of the primary envelope and secondary casing that does not require its propulsion cylinders; those cylinders can be withdrawn so that the line segment rings can be erected; Padded gripper shields extend out to reinforce the sides of the tunnel; Become a platform fixed on which the main propulsion cylinders can push against the front / head armor of cut; With the pinch bearings so busy the secondary propulsion cylinders can be withdrawn from the lined rings of the tunnel to make space and erect the next line ring; once the extraction with the new assembled liner ring is finished; the caliper pads do retract and the stabilizing pads of the armor in front extend to reinforce the armor in front; the secondary propulsion cylinders push against the newly assembled line ring; machine history= The machine has worked on the sites of the SAN BERNARDO for 6.4 km; TARVISIO for 3.0 km and the MORBEGNO for 2.4 km; Before being reused in the MORBEGNO yard the machine was reconditioned for an expense total of approximately two million euro’s (invoices available at request);The first reconditioning was done after a journey 9.4 km; It is therefore to be assumed that the machine is in excellent condition; (ex. CTCC/ caterpillar tunneling Division); machine was nicknamed “Isabelle”; CE certificate available on request (EC declaration of confermity of machinery)
