Boeing 747 lower deck cargo handling systems

Boeing 747 lower deck cargo handlind system | TELAIR

With over 400 systems in-service, the Telair 192100-series lower deck cargo systems have proved to be efficient and reliable.

The systems were introduced as a replacement for the original pulley/belt style tire-drive systems to safe weight, reduce maintenance cost and increase system performance. Customers can choose for either a drive system upgrade or a full lower deck retrofit that would amongst others provide improvements to the restraint system.

This concept led to standard installation of the systems on the Boeing 747-8 model aircraft.
