Electric Tow and Pushback Tractors

pushback · towbarless · gate charging

A pushback lasts a few minutes but moves an aircraft weighing up to hundreds of tons. The battery is sized by pushes per shift, not by distance.

Aircraft maximum takeoff mass a pushback tractor must move, on a log scale: Embraer E175 about 40 tons, COMAC C919 about 79, Boeing 737 MAX 8 about 82, Boeing 787-9 about 254, Boeing 777-300ER about 351 and Airbus A380 about 575 tons. Two tractor designs: towbarless, which cradles the nose gear and can be lighter, and conventional, which uses a towbar and heavy ballast for traction.

Finding

Electric pushback is commercial for narrow-body fleets, and the design variables are pushes per shift, aircraft mix and gate charging, not range

Pushback is a short, high-torque event repeated many times a shift with long idle gaps, which suits batteries. Textron GSE, TLD (TPX-E series), Charlatte, Goldhofer, Oshkosh AeroTech and Mototok sell electric tractors; Mototok's compact remote-controlled towbarless units are common in hangars and at narrow-body gates.

Tractor mass and traction scale with aircraft mass, from about 40 tons for regional jets to about 575 tons for an A380. Towbarless tractors lift the nose gear, using the aircraft's own weight for grip; conventional tractors need heavy ballast. Chargers sit at gate complexes or staging areas, and overlapping turnarounds stack charging peaks on the same feeders - the problem described on Airport Electrification. China's Weihai Guangtai builds electric aircraft tractors for domestic airports.

Autonomy on aircraft is slower than on baggage, because a pushback is safety-critical and coordinated with the flight deck. Remote operation (Mototok) and supervised automated towing trials lead. IAI's TaxiBot, often cited for engines-off taxiing, is a diesel-electric hybrid and is outside ElectronsX scope.
