In 2018, the Ehrlich Brothers toured large arenas with their latest show, Fascination; with the duo, Andreas and Chris Ehrlich, relying on chain hoist systems and controllers from Movecat.
To replace in their entirety the kinetic systems previously used, Ehrlich Entertainment invested in Movecat’s VMK-S 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 7 special versions of the VMK-S-1000 model as climbing hoists capable of lifting loads of up to 1,000kg safely through distances up to 24m.
In combination with the VMK-S chain hoists, the Ehrlich Brothers are relying on 7 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, decentralised 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 key-based 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.
To ensure the smooth and safe operation of their newly acquired chain hoist systems, the Ehrlich Brothers’ technicians attended a training course at the Movecat Academy. In the seminar, Movecat I-Motion Operator Super User, participants are given comprehensive and certified training in the legal and technical fundamentals governing use of the Movecat I-Motion system; the syllabus covers not only the regulations and standards applicable, risk analysis and system configuration but also the structure of the hardware and setting up of components.
