Flexiforce cable drums why 2 safety windings is the safest solution

Why 2 Safety Windings cable drums are the safe solution

WHAT? Defenition Safety Winding (SW) = cable that will always stay “on the drum”, even when door is fully closed.

0,5‐SW: WHY NOT? Drums with 0,5‐SW are allowed (CE) but: • The force applied on the cable end is 5x higher!

• Cable end must withstand 90% of break force cable • Normal aluminum stops are not enough • Steel pressed stops needed (expensive production) • Adjustable fixation (screw) in drum not applicable For industrial doors we strongly advise: 2‐SAFETY WINDINGS!

HOW? 0,5‐SW: force reduction

1000N Force on cable connection

‐50%

2000N (=200kg) weight (door hanging in cable)

HOW? 2‐SW: force reduction

200N Force on cable connection

‐90%

2000N (=200kg) weight (door hanging in cable)

2‐SW: WHY? For industrial doors, 2 safety windings: • is the safest solution in operation and installation • will make life of door producer and installer easier • provides less critical cable fixation • is possible with fully updated quality FF product range:
