Official Launch – Socrano Cougar Long Olven Towbarless Tractor (2005)

Line: Airport Line – Socrano Vehicle Industries (Atego SM)

In January 2005, the manufacturer Socrano Vehicle Industries, based in Atego SM, officially launched one of its most iconic airport line vehicles: the Socrano Cougar Long Olven Towbarless Tractor. This powerful towbarless aircraft tug was the first model of the “Cougar Long” series, making its debut within the manufacturer’s renowned "Airport Line".


-Testing Phase – “Olven Teste” (2004)

Before its commercial release, the vehicle operated at Ategan International Airport throughout 2004, identified as “Olven Teste.” During this period, it underwent a series of rigorous tests focusing on range, durability, and traction—especially with its direct nose gear docking system. The structure was tested with small and medium-sized aircraft before progressing to wide-body models such as the Airbus A310 and Boeing 767.

The results impressed both airport authorities and Socrano’s engineers, leading to an initial production batch of 70 units, which paved the way for its official launch in early 2005.

🔊 Fun Fact:
The engine sound is notably similar to that of the B12M buses—a deep, pressurized growl with characteristic air bursts—often mistaken by ground crews at the airport's technical zones.


-Color Variations

The model was offered in three distinct schemes, each suited for different visibility needs and operational purposes:

1. Glossy White – with subtle light gray markings

Ideal for hot climates and daytime operations.

2. Yellow with Black Checkered Stripe

Designed for high-traffic zones; the checkered pattern evokes industrial warning signals.

3. White with Side Stripe Variants:

Black and yellow checkered stripe

Continuous yellow and red stripe
Used in emergency ops or international airport zones.



-Visual Details

Structural “chest” behind the cab: light gray with black technical markings and operational warnings

Cooling vents and air intakes: built into the body for component cooling

Signal lights: LED beacon bars on top of the cab for night operations

Wheels: reinforced with wide rims for better apron traction



-Impact & Legacy

The Cougar Long Olven marked a turning point for the Ategano airport fleet. Its modern design combined with the rugged Volvo/Socrano B12M engine signaled the beginning of a new era in towing services across Atego SM.

To this day, some units still operate in secondary airports or have been preserved as part of Atego SM’s technological aviation history.
