System for driving power cord connecting aircraft to energy source, has motor gear forming units that drive driving roller forming unit around portion, and pressure roller forming unit associated to releasing units

摘要

The system (1) has motor gear forming units (3) driving a driving roller forming unit (8) around a portion at which part of power cord (2) is rolled. A pressure roller forming unit (7) plates the power cord against the driving roller forming unit. The pressure roller forming unit is associated to releasing units, where the releasing units releases a pinion (9), when acceleration/breaking torque is higher than predetermined value.
