Transfer unit RTU series

Overview
Robotic Transfer Unit RTUn is a steel linear motion platform (7th axis) that extends a robot's workspace. It is a modular, rack-and-pinion driven steel line engineered for heavy payloads and long travel distances, suitable for industrial robot integration.

Key features

• Highly engineered steel structure for high stiffness and heavy-load handling.
• Rack-and-pinion drive enabling extended or potentially infinite travel by joining sections.
• Multiple guidance options: plain guide with tapered roller bearings for smooth motion or recirculating roller guides for higher rigidity and precision.
• Modular design for straightforward mechanical integration and customizable configurations.

Integration and applications

• Extends robot reach for welding, long-part handling, multi-station servicing, palletizing and material transfer across production lines.
• Designed for integration with industrial robots of various payloads and sizes; CAD models and datasheets are available to support design-in.

Available versions

• RTUn: Non-covered steel Robotic Transfer Unit with rack-and-pinion drive. Sizes available for robots from 20 kg up to very high payload robots.
• RTUg: Glide version, steel body, rack-and-pinion. Sizes up to 680 kg.
• RTUs: Smart version, steel body, rack-and-pinion. Broad payload range.
• RTUtc / RTUtcs: Top-cover and Top-Cover Smart versions with steel top protection for debris-prone environments.
• RTUf: Version with guides protected by steel cover.
• RTUe: Elevated version with legs; sizes up to 1200 kg.
• RTUw / RTUi / RTUic: Wall, Inverted and Inverted Crossbeam configurations; sizes up to ~800 kg depending on model.

Technical specifications

• Structure: steel body optimized for stiffness and heavy loads.
• Drive: rack-and-pinion linear drive.
• Protection options: open (non-covered), top cover, full steel cover depending on contamination risk.
• Payloads: versions and sizes cover a wide range (from ~20 kg to very high payload robots).
• Modularity: joinable, self-centering inserts allow long linked travels.
• Resources: CAD files and technical datasheets available to support integration.
