# APCO Technologies SA successfully completed the Factory Acceptance Test

Cometto has been involved with the manufacturing of two 4 axle-lines elevating transporters type ETL 4.

This complex system, which is as huge as a tennis court and weighs 180 tons, will be used at the **Centre Spatial Guyanais** to safely transfer the **Ariane 6** Upper Composite with the Payloads, from the Assembly Building to the Launch Pad.

The development of the UCT started in 2017, and after a stand-by in the qualification process due to the Covid-19 situation, the system arrived in Guyana for Commissioning and Final Acceptance Test campaign.
