Multi-tread vehicles and methods of operating thereof

A method for accessing an interior space of aircraft using a multi-tread vehicle, the method comprising:

• positioning the multi-tread vehicle at an opening to the interior space of aircraft,
• the multi-tread vehicle comprising a first tread section comprising a first front tread portion and a first rear tread portion coupled to the first front tread portion, a second tread section comprising a second front tread portion and a second rear tread portion coupled to the second front tread portion, and a connector section coupled to the first rear tread portion and to the second front tread portion;
• advancing at least the first tread section of the multi-tread vehicle into an opening to the interior space;
• and
• bending a front end of the connector section relative to a rear end of the connector section around a front bend axis parallel to a plane defined by the first rear tread portion using a front connector bend drive of the connector section.

A multi-tread vehicle comprising:

• a first tread section comprising a first front tread portion and a first rear tread portion coupled to the first front tread portion,
• the first front tread portion comprising a first front right tread and a first front left tread,
• the first rear tread portion comprising a first rear right tread and a first rear left tread,
• a second tread section comprising a second front tread portion and a second rear tread portion coupled to the second front tread portion,
• the second front tread portion comprising a second front right tread and a second front left tread,
• the second rear tread portion comprising a second rear right tread and a second rear left tread;
• and
• a connector section coupled to the first rear tread portion and to the second front tread section,
• a front end of the connector section being bendable relative to a rear end of the connector section around a front bend axis parallel to a plane defined by the first rear right tread and the first rear left tread,
• the connector section comprising a front connector bend drive for bending the front end relative to the rear end of the connector section around the front bend axis.
