Axle for towbarless tractors: heavy-duty support for airport pushback operations
A towbarless tractor axle is engineered specifically for towbarless aircraft tractors — specialized ground support vehicles that engage the aircraft’s nose gear directly, eliminating the need for a towbar. These vehicles are used on busy aprons and taxiways where precision and reliability are critical. The axle on this model supports a maximum payload of 5 000 kg, ensuring it can handle the substantial weight of the tractor and any load shifted during aircraft pushbacks without compromising strength or stability.
This high load capacity is essential because towbarless tractors routinely manage forces in multiple directions while handling heavy aircraft, making a robust and well-balanced axle a key factor in operational performance.
Steering performance with hydraulic assistance for precise manoeuvres
Unlike a fixed axle, this product is a steering axle equipped with a hydraulic cylinder steering system. This configuration provides responsive and reliable directional control, which is vital for towbarless tractors that must align precisely with aircraft nose wheels and navigate tight apron spaces.
Hydraulic steering helps operators achieve smooth adjustments and accurate positioning during pushback and towing tasks, enhancing safety and ease of use — particularly where clearances are minimal and accuracy matters.
Disc brake and leaf spring suspension for controlled braking and comfort
The axle is fitted with a disc brake system, chosen for its consistent stopping power and thermal resilience — both important for vehicles that perform repeated braking under load. Disc brakes tend to deliver dependable performance throughout long operational cycles without significant performance drop-off.
In combination, the leaf spring suspension contributes to mechanical simplicity and durability. Leaf springs are effective at distributing vertical loads and absorbing surface irregularities commonly found on access roads and apron areas, which enhances the overall ride quality and reduces wear on adjacent chassis components.
Towbarless tractor axle designed for continuous, demanding airport service
Towbarless tractors are central to efficient ground support operations, and their axles must be engineered to withstand frequent and prolonged use. The combination of a strong load rating, hydraulic steering, disc braking and leaf spring suspension makes this axle well-suited to the demanding conditions of airport aprons and taxiways.
Paillard’s bespoke design approach ensures that each axle is tailored to meet precise operational requirements, enhancing reliability, simplifying maintenance, and supporting safety and performance over the long term in busy airport environments.
