Trusses The ICM has a variety of Prolyte (H40V) trusses available in various lengths for building truss structures. Truss circles are also available (diameters 6 m, 8 m and 10 m).
Chain hoists Room 14 has 24 chain hoists in the audience area and 12 chain hoists in the stage area, each permanently installed and with a maximum capacity of 500 kg. In keeping with BGV C1 (guidelines for use above audiences), they are equipped with double back-up systems and do not require any additional load-securing devices. Programmed movements are not possible with these motors. There are also 16 portable chain hoists available, each with a capacity of 1,000 kg (rigging motors as defined by BGV D8). They are controlled using a separate control system (combining C1 and D8 hoists is not possible).
Overhead machinery Room 1 Room 1 is equipped a sophisticated network of overhead machinery that consists of 16 machine hoists, 1 skylight hoist, 4 panorama hoists, 8 point hoists (stage) and 6 point hoists (room). The maximum capacity of each hoist is 500 kg. The Guddland control console installed in Room 1 can be used to program complex movements of all hoists for scene changes - including those synchronized with regard to time and route traveled - priot to the event and have them executed at the push of a button.
Stage machinery Room 1 The stage in Room 1 consists of 9 rising platforms and 2 forestage platforms. The 9 rising platforms can be adjusted from 0.00 m to +2.00 m (0.00 = room level). Forestage platform 1 is a two-story platform and can be adjusted from 0.00 m to +1.00 m. Forestage platform 2 is normally kept at room level. However, if the seats that are installed there are removed, it can be raised to stage level (+1.00 m) or lowered by up to -1.80 m. In this case, it can be used together with forestage platform 1 to create an orchestra pit. The platforms move at a speed of 2.5 cm/s.
