Each Elevation 1+ Variable Speed hoist controller allows the variable speed running and full positional control of an electric chain hoist via an RS485-based protocol. The unit itself also incorporates a full variable-speed manual control plus remote handset control for basic running. Units can be daisy-chained together for easy set-up of multi-point lifts.
Summit is using Kinesys' Vector Motion Control software as the primary show control. Vector is a fully-featured motion control sequencing system that can control both variable and fixed-speed devices. It offers cue editing and running facilities for easy programming and use. There's also a comprehensive manual running section which enables fast, simple movement of individual or grouped devices. Other advantages of the control software include its safety elements. The software contains an integrated alarm system which reads the status of 'external' digital inputs across the system, so the operator can monitor as many limits and emergency stops as required. Simulation mode allows complex cues to be created and run off-line for safe testing, with information sent and received on Ethernet via the mains distro.
Complementing the system are two of Kinesys' PD-ES power distros which distribute power to the entire system, relay data from control to the Elevation 1+s and provide e-stop facilities, allowing the system to be stopped in up to two positions remote of the distro. The distro is the hub of the system. Each one can run up to 24 hoists on a 125A three-phase supply via Camloks, and also provides 16A single-phase power for control. The distro unit also converts Ethernet to the more robust XLR7 control cable used to feed the Elevation 1+s.
Summit's 30 LL Lodestars were bought specifically for use with the Elevation 1+ but have the added benefit of being easily converted to manual use - so Summit can deploy them for a wide variety of scenarios. The Lodestars are specially modified from the standard Model LL Lodestar with Stromag BZ3.5 double brakes and rotary cam limit switches, quadrature encoders for high resolution positioning and ILME multipole connectors for direct attachment to the Elevation 1+s.
The system was purchased by Summit from Brilliant Stages who originally commissioned it for the Robbie Williams 'Escapology'/'Weekends of Mass Distraction 2003' and for Bon Jovi's 'Bounce' tour, both in 2003. It's also been in action on The Brits 2004 and providing moving LED screens for MTV, and is currently on tour with Pink. The system is available from Summit Steel or via Kinesys.
