SCHKEUDITZ, Germany – It is 10 p.m. at Leipzig/Halle airport. A freight plane touches down laden with about 15 air freight containers – business mail, computers, smartphones, and pharmaceuticals. The flight schedule is defined; everything must run efficiently. Containers are pulled out and loaded onto MULAG towing tractors. The vehicles carry the freight to the 413 meter-long distribution center, called “the warehouse”. There a 6.5 kilometer-long fully-automatic sorting ally is ready and waiting.
DHL Hub Leipzig, located in Schkeuditz, Saxony, currently operates 128 MULAG towing tractors with 4-cylinder Deutz diesel engines (64 kW / 87 hp) and Allison 1000 Series fully-automatic transmissions for container handling. The first 80 vehicles were delivered in 2007, when the test operation at DHL Hub Leipzig began. Constantly growing cargo volume has required an increase in towing tractors, with the last 10 added in March 2013.
“We always reorder the same vehicle models to maintain fleet purity. That way, the drivers don’t have to be retrained,” explained Jens Freund, Duty Manager of Ground Support Equipment at DHL Hub Leipzig.
The Deutsche Post specified high-traction towing tractors for the air freight hub of its express and logistics subsidiary, DHL. “Therefore we equipped the MULAG towing tractors with Allison 1000 Series fully-automatic transmissions. They have several gears – six forward and one reverse – and in combination with a robust industrial diesel engine they are perfect for handling heavy freight,” said Hubert Bitsch, who is responsible for service ground-support vehicles at MULAG.
These Allison-equipped Comet 6 towing tractors operate mainly between 10 p.m. and 6 a.m., while more than 55 freight planes land and take-off at DHL Hub Leipzig; some vehicles are also needed during the day.
Altogether, the towing tractors move 900 containers daily on average, each weighing a remarkable two to five tons. A total of 17 tons at a time can be moved by the vehicles’ small and agile power packs at a maximum speed of 30 km/h.
“The Allison fully-automatic transmission is very operator-friendly. You only have to choose the forward or reverse gear, and then you can accelerate. The transmission is low-maintenance, robust and reliable; it transfers engine power to the wheels without interrupting traction, enabling a fast approach. This is very important, because the time frame for freight handling is narrow. Manual transmissions would not work in our business,” finished Freund succinctly.
