There are 3 different types of GH3 rails: A, B and C each specially designed to tackle particular spans and lifting weights. Combining these appropriately makes installation an easy, rapid process.
The rails can be mounted on the ceiling, on walls or on supporting pillars - or any combination of these. The unsupported span can be as much as 8 metres, depending on the combination of rail types specified and which weights the system must be capable of bearing.
It is possible to build in the rails in rooms with suspended ceilings, so that only the lower side of the rail is visible, both in connection with single track and room-covering systems.
If the rails are mounted on the ceiling itself, they can be made to blend discreetly into the surroundings by use of colour or decoration.
A-rails are normally used in single track systems, as curves (30˚, 45˚, 60˚, 90˚), switch tracks and turn tables are the same height as the A-rail.
The traverse rail can be intermediately hung or underhung.
