The Estrel Berlin, Europe’s largest hotel, convention and entertainment centre, has considerably expanded its meeting and events complex: with the opening of the new Convention Hall II, 10,000 square metres of additional events space are now available. On its three levels, Convention Hall II offers 4,600 square metres for up to 5,200 people, a 1,500-square-metre hall for 900 people, one 700-metre foyer, four meeting rooms for up to 100 people, and three additional lounges.
For a highly modern events area such as Convention Hall II, in terms of technical equipment, state-of-the-art material capable of satisfying the highest expectations was required: for this reason, the decision-makers opted for a kinetic system from Movecat. In all, ninety-six Movecat Pluslite 1250 D8 Plus electric chain hoists with two-track operation limit switches including the X2 Option Kit that also in the case of 400 V direct drive hoists allows the determination of working limits without requiring addition control leads were installed beneath the ceiling of the new events hall. Twelve Movecat MPC 4ID8 High Power Controllers housed in a variety of system racks serve as the control platform for the system; high-performance PDU Power Stations provide the power for each rack, with these and all the cabling derived also from the Movecat product range.
The kinetic solution from Movecat makes it possible to ‘fly’ loads of up to 1,250 kilograms from each of the ninety-six chain hoists beneath the hall’s self-supporting roof with its span of 75 metres. That is the equivalent attaching of a total load of 120 metric tons, or 100 automobiles, to the 11.5-metre ceiling of the hall. Impressive numbers that underline the future-readiness of the new events areas. Due to the potentially enormous loads, each hoist is supervised by an integrated LME load-measuring system. In connection with the MPC 4ID8 controllers, it is possible to prevent overload or underload conditions arising; moreover, the entire system is equipped with a digital buss system by means of which the load conditions and states of all hoists, individual load groups, and the total load can be supervised and documented in 24/7 mode on a laptop PC running Movecat’s AS-1 software. The entire system therefore complies with the current SQ P2 requirements for complex indeterminate load systems.
“In order to realize complex events safely in very short order, it is essential to have at your disposal reliable equipment and equally reliable controllers,” explains Thomas Herzberg, Technical Director of Events Equipment with Estrel Berlin. “After conducting many preliminary discussions and giving careful consideration to the material options, we decided in favour of this system employing ninety-six motors from Movecat. Thought, in fact, is being given already to the expansion of this Movecat system to equip further areas of the new hall complex.”
