Ehrlich Brothers’ illusions rely on Movecat
- Details
On their current tour, for example, the Ehrlich Brothers are making an eight-ton, 2,000 BHP monster truck materialize on stage out of nothing as well as "teleporting" individual spectators right across the hall.
To realise a production of such complexity, the Ehrlich Brothers have been relying on chain hoist systems and controllers from Movecat. To replace the kinetic systems previously used, Ehrlich Entertainment GmbH invested in Movecat‘s VMKS chain hoists, V-Motion-E variable motion controllers and I-Motion Basic-C show controllers.
The Movecat VMK-S chain hoists, which comply with BGV C1, DIN 56950:2012- 05 and EN 61508 SIL 3, are notable for their innovative technology and ultra-flexible handling whilst meeting the highest safety standards. Henceforth, Ehrlich Brothers productions will employ seven special versions of the VMK-S-1000 model as climbing hoists capable of lifting loads of up to 1,000 kg safely through distances up to 24m.
In combination with the VMK-S chain hoists, the Ehrlich Brothers are relying on seven Movecat V-Motion- 40-E-SIL3 variable motion controllers in their ‘E’ configuration. Unlike the basic version, these are equipped with special integrated network and motor filters and a dual processor for scenic runs over people in mobile, decentralized operation as defined by SIL3-EN 61508.
The I-Motion Basic-C II show controller functions as a compact system controller for the systemic control of kinetic drives. The intelligent controller console is equipped with an integrated 12" touchscreen, a keybased input unit, a user ID card reader, a speed ratio encoder and a drive lever with a ‘dead man’ function, for the dynamic control of runs performed by up to 24 VMK-S chain hoists in conjunction with the V-Motion controllers.
