ChainMaster chain hoist system for Helmut List Halle in Graz
Austria – Since the market launch of ChainMaster products in 1994, the Saxon-based company has developed into one of the world's leading manufacturers of hoist technology in the event industry and offers a comprehensive range of products for all requirements from set-up operations to complex scenic movements to complete automation of performances. National and international projects are accompanied individually from planning to implementation as well as user training. The worldwide network of ChainMaster Consulting Offices, commercial partners and trained service companies guarantees comprehensive after-sales service.
In August 2019, ChainMaster delivered a new chain hoist system to its long-standing Austrian sales partner A.T.C GmbH, based in Wulkaprodersdorf, Austria. A.T.C GmbH carried out the assembly and installation of the system on site in the Helmut List Halle in Graz.
For this project, ChainMaster supplied 38 VarioLifts 1000kg with a two-fall design and a continuously variable speed up to 4.8 m/min and a maximum lifting height of 12m. The drives are controlled by the XYZ control system, certified according to EN/IEC 61508 SIL3. The control system is currently designed for a maximum of 42 drives. The system is operated via a control panel with a 19" touch screen, equipped with two travel levers with deadman switch. Two safety computers with self-monitoring and Internet access for remote maintenance operate in the background of the control system.
The ChainMaster XYZ Control System is ideal for creating complex motion sequences and is therefore a reliable interface between operator and stage drives. The straightforward user interface and the practical configuration of the functions enable simple and intuitive operation at the highest level of safety with constant access to the hoists integrated in the system.
To control the chain hoists, the Helmut List Halle is equipped with a control cabinet system of six units each for four drives and six units for three drives. Equipped with state-of-the-art closed-loop frequency converters, high-resolution displacement sensors and safe load evaluation enable programmable start and stop ramps, full torque at standstill over several minutes, direction changes without interruptions and make the ChainMaster Variolifts a hoist of the highest performance.
