RTU Systems
What Is a Robot Transfer Unit?
A Robot Transfer Unit (RTU) adds a linear 7th axis that allows a robot to travel along a track system. This expands the robot’s working envelope so it can move between multiple machines, workstations, or processes along a production line.
By enabling one robot to handle more tasks across a larger area, RTUs improve flexibility and productivity while reducing the need for additional robots. Both industrial robots and cobots can benefit from this extended range.


Bishop-Wisecarver® RTU Systems
Engineered for critical environments and designed for seamless integration into turnkey automation systems, Bishop-Wisecarver Robot Transfer Units (RTUs) extend the reach, capability, and efficiency of industrial and collaborative robots. Welding spatter, abrasive debris, and temperature extremes pose serious challenges that can shorten the life of conventional linear guide systems. Bishop-Wisecarver® 7th-axis RTUs, powered by proven DualVee Motion Technology®, are purpose-built to thrive in these demanding environments, delivering durable, precise, and scalable solutions where reliability matters most.
Powered by Bishop-Wisecarver’s DualVee® Motion Technology, these RTU systems are engineered for reliable operation in demanding automation environments.
The LoPro® RTU platform is designed to provide accurate, belt-driven motion for light and moderate payload robots. Engineered for durability, ease of installation, and seamless integration into turnkey automation projects. Available in Light (RTU-L), Inverted Light, and Medium (RTU-M) configurations.
For moderate to heavy robots and demanding industrial applications, the DualVee® RTU is engineered from the ground up to deliver high load capacity, precision positioning, and scalable modular construction.
The Vertical Robot Transfer Unit is engineered to extend the capabilities of small robots or cobots by enabling vertical movement, thereby significantly expanding their working envelope.
Engineered for Seamless Integration
Bishop-Wisecarver RTUs are designed for rapid deployment into automation systems. Each system is configured with robot-specific mounting patterns and supports multiple motor and gearbox options to align with application requirements.
Our Application Engineering team assists with sizing, load validation, life estimation, and custom configurations to ensure the system performs reliably under both static and dynamic conditions. From standard configurations to complete mechatronics solutions, we deliver guidance that reduces risk and accelerates implementation.
HepcoMotion® Heavy Duty RTU Systems
Looking for additional heavy duty RTU options? The reliable and versatile HepcoMotion® HDS2 and MHD family of products support and transfer heavy industrial robots or those carrying high moment loads.
A versatile transfer and positioning system, HDS2 handles heavy loads with high reliability and precision making it ideal for moving cartesian, polyarticulated and “hybrid motion” robots.
Designed to transport heavy automation equipment, MHD track roller system accommodates high offset and overhanging loads and is ideally suited to be used as a 7th axis robot transfer.
