Unified Lube Free Air Tractor

What is the maximum travel speed of the air tractor?

The Unified Lube-Free Air Tractor operates at speeds up to 4 feet per second, making it suitable for applications requiring efficient, consistent motion along enclosed track systems.

What control options are available for different system requirements?

There are four control package options (C1–C4), ranging from basic base units to fully integrated SMC control packs with 2- or 4-button pendants. This allows engineers to select the right level of control for their application—from manual to automated integration.

Is the air motor truly maintenance-free?

Yes. The air motor is designed to operate without lubrication, reducing maintenance intervals and eliminating the risk of oil contamination in clean environments.

What track types and sizes are supported?

The tractor is compatible with Unified ETA-4, ETA-5, ETA-8 enclosed tracks, as well as S4, S6, S8 I-beams and patented track profiles. This ensures broad compatibility across various crane and monorail systems.

Can the tractor be configured with braking or towing accessories?

Yes. Optional tow bar assemblies are available for different track sizes, and while the standard configuration is “no brake,” braking options may be available upon request for applications requiring controlled stopping or holding.
