Nowadays sets and show decorations often feature moving elements. In the positioning of these loads (which often weigh tons!), the highest degree of precision and absolute safety are called for. It is in just such situations that the VarioTrolley from ChainMaster comes into its own. The VarioTrolley had its baptism of fire in 2001 at the Eurovision Song Contest in Copenhagen, when 24 of the trolleys combined with a ChainMaster BGV C1 chain-hoist and a ChainMaster as failsafe controller in a display of kinetic virtuosity witnessed by tens of millions across the continent. The system was used to manoeuvre eight semi-circular truss structures horizontally and vertically over the stage and formed the centrepiece of the set design. And the result? ChainMaster: 12 points!
