US carrier Southwest Airlines has received its latest Lektro towbarless electric tug under a programme to replace its fossil-fuelled fleet of tractors with 56 Lektro vehicles.
The AP8950SDB-AL-200 model tug, to be used by Southwest at San Jose International Airport in California, is the second largest pushback model in the Lektro range. It can handle narrow body aircraft such as the B-737 and A320.
The patented universal nose gear lift cradle on the tug is activated by an electric/hydraulic pump assembly, which can handle dual- and single-wheel aircraft. Electric/hydraulic steering is controlled through an automotive-type tilt wheel. An automatic timer turns off power when the tug is not in use to increase battery life between recharges.
