One Tug, Category Selection, Zero Guesswork
Select the aircraft weight category and Sierra calibrates the safe power output to match.
The Sierra Series was built for operators who can’t afford to guess. Every Sierra tug ships with aircraft-specific software calibrated to your fleet, continuous torque monitoring through Torq Sense™, and Auto Throttle protection that adjusts power output in real time — so nose gear stress never becomes a liability conversation.
What sets Sierra apart on a commercial ramp is the optional touchscreen controls with employee ID-based access, GPS tracking, and data logging on every move. When something happens on the ramp, you have the record.
Built for the People Who Run It.
Real-time protection for the aircraft and passive protection for the operator is what separates this commercial-grade tug from others
Torq Sense / Auto throttle
Fully automated power outputs for maximum nose gear protection.
The Sierra series of commercial tugs monitor nose gear torque in real time, making 100 decisions per second and adjusting power output instantly. When force approaches the safe limit for the specific aircraft type being towed, the tug throttles back automatically, before the operator can react and before damage occurs. This feature combined with load category selection makes Sierra the most advanced commercial electric tug on the market.
Designed for Any Operator
The optional touchscreen and dead mans switch minimize human error
Every Sierra ships standard with manual weight category selection that is simple, reliable, ready to go. Upgrade to the optional touchscreen and Sierra becomes aircraft-aware with smart loading that applies the exact torque and lift height specific to the aircraft you’ve selected, a wheel direction indicator keeps operators oriented, and every move is logged. It’s the difference between a tug that moves aircraft and one that’s calibrated to each one individually.
Wing Walker With a Stop Switch
ETSO puts real-time control in the hands of your ground crew.
Miscommunication on the ramp isn’t a minor risk — it’s how a $2 million aircraft ends up scraped against a wall or another plane. ETSO gives wing walkers a one-press remote stop, backed by encrypted, fail-safe communication, so any member of your crew can halt a move instantly from a safe distance. No training manual required, simply pick up and go.
Built for the Ramp.
