If the uniformly distributed load needs to be upgraded from 300 to 500kg and the point load from 40 to 150/200kg, a normal fly-bar will not have the required strength, and the single round tube is often replaced with ladder beams, usually made from steel. ProTrac offers an alternative to the steel ladder beams, specially designed to meet the demands from a modern theatrical environment.
ProTrac is a combination of a square profile extruded aluminium tube underneath which a round tube of 60mm or 48.3mm is attached. Suspension points slide into the square profile and can be locked at any desired place. ProTrac is very flexible in use; several lengths can be easily combined and connected. ProTrac offers a unique solution for all situations where a simple bar or ladder beam no longer meets requirements. ProTrac can be installed in all theatres or other venues, without any adjustments to the existing construction.
Prolyte is taking the opportunity to let the UK theatre community view the system at the ABTT Show (London, 18-19 June) ahead of its official launch at the PLASA show in September.
