Zaugg railway snow clearing equipment

Zaugg supplies railway snow clearing equipment that is designed and built to the customer's specification. The company plans and carries out demanding snow clearing projects together with railway companies all over the world, and production takes place in its own workshops in Eggiwil, Switzerland. The range falls into three categories: add-on equipment mounted on existing work vehicles, complete service vehicles, and special machines for infrastructure such as cable cars, people movers and monorails. Solutions can be built with or without a cab, and existing infrastructure is taken into account from planning to finished machine.

Add-on equipment

The add-on equipment comprises a snow blower, snow plough, track sweeper and power pack. The SF 72-70 snow blower clears from 10 mm above the top of the rail, with a width of 3 150 mm when the units are retracted and 4 550 mm when they are extended. Each unit can be extended 700 mm outwards independently of the other and raised 600 mm above the top of the rail. It requires 170 kW, handles around 1 940 tonnes per hour and weighs around 2 500 kg including the lifting device. The K10-Vario wedge plough has hydraulically adjustable plough wings, PUR wear steel and Gjerstad mountings, and clears a width of 2 920 mm.

Service vehicles

The service vehicles include a push-type snow blower with cab, the SF 120-100, which is pushed by a locomotive and powered by a Cummins QSX15 of 447 kW. It clears a width of up to 5 900 mm with the units extended, requires 400 kW and handles around 3 800 tonnes per hour. The K20-Vario snow plough wagon is also pushed by a locomotive, has electrically driven hydraulics and a turning jack for changing direction, and clears a width of 3 300 mm. The self-propelled ZRR10000M has two Caterpillar C18 engines of 470 kW each and a superstructure that can be rotated 180 degrees to change the working direction.

Power pack

The power pack supplies the add-on equipment with hydraulic power independently of the carrier vehicle. It has an MTU 4R1000C50 in Stage V / Tier 4f that delivers 170 kW (231 hp) at 1 800 rpm, a three-section variable pump, working hydraulics of up to 300 bar and 150 l/min, and is operated from a panel in the cab. The KM90 track sweeper has a hydraulically driven brush roller with infinitely variable speed control and a parallelogram with a lifting cylinder, and is attached to the service vehicle with Gjerstad mounting points.
