The Sunkid Convoyer belt helps save energy

New developments at the Brunni-Alpthal and Nendaz Ski Resort (CH). Thanks to technical innovations, the Sunkid conveyor belt makes an active contribution to the reduction of energy costs.

Ski resort expansion for the most part entails increased energy costs. The Nendaz Region however, as member of “Eco-Guide,” has a keen interest in sustainable development in the ski resort. For this reason, a Sunkid conveyor with the “Eco Save“ access control featuring automatic shut-off is being operated. A different approach is pursued at the Brunni-Alpthal ski lift, where as part of the resource conservation effort, a Sunkid conveyor belt is operated using renewable solar energy.


“The solar facility integrated directly into the operations building produces even more energy than is needed to operate the 164-foot (50-meter) long conveyor belt,” notices Raphael Auf der Maur, Managing Director of the Brunni Ski Lift in Alpthal, satisfied with the success over the past season. The conveyor belt transports skiers, snowboarders, as well as lugers. The slip-resistant Blue-Eye surface of the belt as well as the continuously variable adjustment of speed ideally support this application well.


The conveyor belt needs less energy than the solar facility produces


To further improves logistics within the ski resort in Nendaz (Quatre Vallees), a 426-foot (130-meter) long and approx. 2-foot (750-mm) wide Sunkid conveyor belt with Blue-Eye surface was installed there. It features an 18.5 KW motor, controlled by an "Eco Save” access control system. This means that the conveyor moves only if passengers approach it or are riding it up the hill. If there is nobody standing on the conveyor belt, the belt stops after a few seconds and does not consume any energy during this time. The system is thus comparable with the “Start-Stop” automatic system used in automobiles.

Moreover, a light signal installation provides for controlled access to the conveyor belt. Thanks to this measure, the power of the motor can be efficiently adapted to passenger load. The conveyor belt is used in the ski resort as a climbing aid for the beginners’ area for one, and as a return route for cableway passengers for another.
