The aerial robot tractor MTU-7 can carry a record weight of ten tons thanks to its enormous traction and heavy-duty cables. The Bumblebee is used in heavy industry, construction, and oil drilling, moving through the air as an indispensable tool for access to obstructed objects.

It is often used with the NA-T256 Natasha, which receives heavy loads or passes them to the Bumblebee. In addition, the MTU-7 is a staple of emergency rescue units and is ready to swoop in to assist should a serious industrial accident ever occur.
