QUESTIONS & ANSWERS
The Tronair A003819D towbar is specifically designed for Boeing 737 100-900 aircraft. It is engineered to match the nose gear configuration and towing requirements of this aircraft series. Using a model-specific aircraft towbar ensures proper fit, alignment, and safe pushback operations. Always confirm compatibility with the aircraft maintenance manual before use.
The clamp-type head assembly securely engages the aircraft nose gear to maintain stable alignment during towing. Proper engagement reduces the risk of slippage or uneven load distribution. The design allows operators to attach the towbar to the aircraft first, then connect to the tug, helping minimize the risk of aircraft damage. Secure attachment is critical for safe pushback and repositioning.
The A003819D includes shear bolt protection designed to help prevent excessive load transfer to the aircraft structure. Shear bolts are engineered to fail at predetermined loads, protecting both the towbar and aircraft nose gear. Only Tronair-approved shear pins should be used to maintain proper load limits. Replacing shear pins after failure is essential for continued safe operation.
Yes, the A003819D is equipped with a hydraulic combo pump and lift assembly. The hydraulic system allows operators to raise or lower the towbar landing gear for proper height alignment and transport. Proper hydraulic use helps keep the towbar level during towing and reduces unnecessary stress on components. Regular inspection and maintenance of the hydraulic system is recommended.
The maximum recommended towing speed is 10 mph (16 km/h). Exceeding this limit may result in damage to the aircraft, tug, or towbar. Controlled speeds help maintain safe load transfer and minimize stress on the nose gear. Operators should also avoid sudden starts and stops.
Operators should not exceed a 90° angle between the tug and towbar during operation. Excessive angles can cause damage to the towbar or aircraft. Tronair recommends maintaining smooth, sweeping turns and avoiding sharp pivoting. Proper alignment ensures safer pushback procedures.
Tronair recommends attaching the towbar to the aircraft first, then connecting it to the tug. This procedure reduces the risk of accidental aircraft contact during alignment. Ensuring the aircraft attachment is fully locked before towing is critical. Following the proper attachment sequence enhances operational safety.
Daily inspection should include checking the towbar for physical damage, ensuring proper head operation, and verifying the condition of the shear bolt. Operators should also inspect the eyebolt, wheels, hydraulic system, and weldments for cracks or deformations. Damaged or bent towbars must not be used. Routine inspections help prevent equipment failure during towing.
Routine maintenance includes daily inspections, bi-yearly shear bolt checks, lubrication of axle pivots, hydraulic fluid checks, and annual bearing repacking. Greasing with Lithium EP2 or an equivalent is recommended. Proper torque procedures must be followed when replacing shear or retention bolts. Preventative maintenance extends towbar service life.
Tronair recommends maintaining a shear bolt replacement kit (K-5581), a cylinder seal kit (15O6017), a handle pin kit (15O6235), a tire and hub assembly (15F3288), and other critical spare components. Keeping approved OEM replacement parts available minimizes downtime. Only OEM parts should be used to maintain warranty compliance. Ready access to spares supports uninterrupted ground support operations.
