Trusses The ICM has a variety of Prolyte (H40V) trusses available in various
lengths for building truss structures. Truss circles are also available
(diameters 2m, 4m, 6m, 8m and 10m).
Chain hoists Room 14 has 24, room 13 8 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.
