Choosing an electric hangar tug starts with the airplane, not with a catalogue of options we have not published. Infinity Tugs states a towing capacity on each machine that is available today. If your airplane sits inside that sentence, that is the tug to confirm. If it does not, we say so.
A single-engine piston such as the Cirrus SR22 is the type named on DISCOVERY. The published limit is 2,500 kg on straight ground. It is hand-steered, one gear, forward and reverse, with a manual winch onto a glass-fiber deck. It extends to 210 cm to tow and folds to 120 cm to store. Ramp load is 500 kg. Grass and asphalt are both specified. That is the electric tug for that class of single.
Cessna and Piper types through light twins are named on ROVER, not on DISCOVERY. ROVER is remote-controlled and 27 cm tall, so you can walk the wingtip while the tug holds the nose wheel. Towing capacity is 5,000 kg, or up to 7,000 kg depending on configuration. Ramp load is 750 kg. The remote is included. A lighter single inside 2,500 kg can still be checked against DISCOVERY. We do not publish a model-by-model list, so the quote is where that check happens.
A light jet or turboprop is GRAVITY. The page names the Cirrus Vision Jet, the Daher TBM series and the Pilatus PC-12. Towing capacity is 5,000 kg, or 7,000 kg with the optional upgrade. The drive is 48 V and 1,200 W, with an electric winch. Ramp load is 750 kg. There is also a Vision Jet edition of the same tug, with a glass-topped deck cut to that nose wheel. DISCOVERY's 2,500 kg rating is not the one we use for these aircraft.
Two machines are not part of this choice yet. CHALLENGER is a coming-soon ride-on for large-cabin business jets, and it has no published towing figure. If that is what you fly, tell us, and we will not pretend a walk-behind tug is the same tool. Skid helicopters are a different range: DISCOVERY H for light skid helicopters such as the Robinson R44, up to 2,500 kg. HELI PAD and HELI LIFT stay marked coming soon.
The practical questions we can answer from the published data are the ones above: which rating, one person or a remote, grass or asphalt, and whether the airplane is a single, a light twin, or a light jet or turboprop. Request a quote with the type and the surface. There is no price on this page, and no test result beyond the capacities already printed on the product pages.
