echnical analysis reveals the dramatic impact of cable/rope weight on elevator system performance .
Conventional Steel Rope Example (500m travel):
Moving masses: ~27,000 kg (equivalent to 10 off-road vehicles)
Constraint: Rope weight becomes so heavy it can't carry its own load
Result: Sky lobbies required for very tall buildings
KONE UltraRope Example (500m travel):
Moving masses: ~13,000 kg (equivalent to 4 off-road vehicles)
Enables: One continuous journey from ground to penthouse
Benefit: Eliminates need for sky lobby transfers
