Ground Stacking WPC - Upward Tilt
Ground stacks of WPC cabinets are assembled using the Touring Flying Frame. The front stabiliser bars provide a wide and
stable platform for assembling an array of up to six WPC cabinets. Ground stacks can be assembled with either a positive or
negative array inclination relative to the ground simply by alternate positioning of the Ground Stack Bar. This example is shown
with positive (up-tilt) array inclination.
” Place the Touring Flying Frame at the desired location. Position the first cabinet on top of the bar, aligning the lower front
rigging points with the rigging points on the bar. Secure with Rigging Pins on both sides. Attach the Ground Stack Bar at the
-17.5° position on the Touring Flying Frame and secure with a Rigging Pin. Secure the Ground Stack Bar to the first cabinet
with a Rigging Pin at the LINK position.
