In the world of aircraft ground handling, few names command as much respect as TLD . Their ACU series of towbarless aircraft tugs are industry benchmarks, and the TLD ACU-302-H-CUP is no exception. Designed for pushback and maintenance towing of narrow-body aircraft (such as the Airbus A320 family and Boeing 737 series), this unit combines hydraulic power, electronic steering, and a unique "cup" coupling system.
