Cynergy Ergonomics Case Study
REQUIREMENT:
Composite aircraft stringers require a rigid handling system
to transport the stringer and compactor assemblies from the
forming station to the mandrel. The stringers are 40 ft.
long, weigh 15 lbs. and are extremely flexible. The
composite plies, once molded to the compactor, must be held
rigidly in place onto the compactor throughout the handling
process. Lastly, 40’ long bladders must accompany the
stringers/compactors throughout the assembly and placement
process.
SOLUTION:
A rigid lifting beam handling system is utilized for the
manipulation of the stringer assemblies. Each beam
incorporates a vacuum plenum with multiple ports/valves
designed to mate to designated ports on the compactor
providing a system for accurately holding composite plies in
position. The beams utilize adjustable bracket locations to
accommodate various stringer sizes and to accommodate the
handling of multiple stringers simultaneously. In addition,
linear guide rails are provided on each bracket in order to
allow for transverse movement of the stringer assemblies
while being supported by the lifting beam system. The
stringer handling systems incorporate a radio control
allowing the operators to move about the area as needed
while handling the various components.
