It is built around twelve of ChainMaster's new 250 kg VarioLifts, which are capable of speeds up to 35 metres per minute. For the project, ChainMaster is working in concert with the Rock Stage Agency, its local distribution partner.
The VarioLift from ChainMaster came onto the market in 1998 after an 18-month development and test phase. It offers maximum precision and reproducibility in the positioning of chain hoists, the company reports. The lift is based on an integrated, vector-controlled frequency converter, supplied by a high-impulse incremental encoder and operates with a positional accuracy of 0.2 millimetres. VarioLifts were used on U2's Elevation Tour, the concert tours of Blink 182 as well as Matchbox-20 and the premiere of the film Pearl Harbour. They are suitable for both fixed installation and mobile applications.
