Dual View Dumpers: Application in the Karawanken Tunnel

Eight Wacker Neuson Dual View Dumpers impress on the tunnel construction site.

A large-scale operation with little space - at this challenging construction site, eight Dual View Dumpers DV90 by Wacker Neuson show that they are ideally suited to this kind of task. With the operating and seat console that can be turned 180 degrees, material transport in Strabag AG's construction work in the Karawanken Tunnel is no problem, as strenuous turning and maneuvering are no longer necessary thanks to the rotating seat.

6 months, 7 days a week, 24 hours a day and 1,500 hours in action in total: the dumpers, with nine metric tons of payload, transported material in shift operation on the major construction site of the Karawanken Tunnel. To bring the 115-year-old train tunnel between Austria and Slovenia up to a safe and modern condition, the tunnel is being converted to one track. In addition, the tunnel vault and the portal structures, listed as historic monuments, are being restored, and a contemporary drainage system is being installed. Due to the confined spaces, the executing construction company, Strabag AG, decided on Wacker Neuson's Dual View Dumpers: 'When modernizing the Karawanken Tunnel, it was important for us to be able to rely one hundred percent on the machines used there,' explains the project manager of Strabag AG. 'The eight dumpers mastered their task perfectly under demanding conditions. The rotating seat was especially ideal for this construction site, as there is very little space to maneuver in the tunnel.' In total, just short of 40,000 cubic meters of material were transported out of the tunnel using the dumpers.

Dual View allows the operator to conveniently and quickly change the seat position through a 180-degree rotation of the entire operator control panel and the seat console. The operator changes the direction of view and the forwards travel direction with the seat position. Time-consuming turning and maneuvering are therefore no longer necessary - a huge advantage in the confined spaces in the Karawanken Tunnel. The operator steers the wheel dumper with the unladen skip in the travel direction into the tunnel, loads it with a full view of the loading area and, after a 180-degree rotation of the seat, drives away again in the same way with a free line-of-sight without having to turn the vehicle. In this way, he always has the working environment in full view, which means significantly more safety. Even a fully loaded skip no longer blocks the view, because the operator leaves the skip behind him during travel, as with a truck.

Intuitive, safe, comfortable

Time-tested and proven safety features such as the hydrostatic drive system, the wear-free spring-loaded parking brake, and operation via joystick, which allow the operator to always keep a hand on the steering wheel, ensure the simple and intuitive operation of the Dual View Dumpers. 'Beside the reliability and power of the machines, the easy handling convinced us,' adds the project manager. 'Due to shift operation, the operators change frequently, meaning that intuitive operation is particularly important for us. And: we save valuable time on instructing our employees.' A sturdy protective grating on the skip also protects the operator and the cabin, for example against damage from an excavator arm. The cabin, for which an optional heater and air-conditioning system are offered, provides more comfort.

Efficient Load Carrier

Wacker Neuson wheel dumpers can do all the traditional transport work, but also offer additional advantages. Thanks to their articulated pendulum joint, they are much more maneuverable and off-road capable than trucks and can also be used on uneven terrain. Even under full load, they always remain in contact with the ground and retain very good traction, even in uneven terrain. Thanks to the variable 180-degree tilting, a flexible swivel tip skip ensures that material can be precisely distributed. Overall, with the three Dual View Dumpers DV60, DV90 and DV100 with six, nine and ten metric tons payload, Wacker Neuson offers its customers 20 different models of track and wheel dumpers, which are characterized in particular by simple and safe operation as well as comfort. They can be flexibly outfitted and used to meet individual customer needs.
