Standing for Big Frame Truss, this roof design with PA wings is
true to its name as it features 26” x 36” crossstage truss, 26”
x 43” end truss and folding 26” triangle truss as the up-stage/
down-stage part of the grid. The system utilizes 16” x 16”
towers. The general dimensions of the BFT are 60’ x 40’ (18.29
m x 12.19 m), plus 20' x 20' PA wings on each side. It claims a
safe operating wind speed of up to 67 mph and the live loads
(equipment loads) that can be applied to the system include
a 60,000 pound (27,216 kg) uniformly distributed load (UDL)
on the main grid and a 24,000 pound (10,886 kg) speaker
load on each PA Wing - making it the right choice for a range
of applications
