PR2 for shuttle applications

Reliability is the core of the new 2-pole conductor bar system, developed to meet the growing demand for compact conductor bar solutions. Leading manufacturers of shuttle systems require specific solutions to ensure compact, touch‑safe integration at high speeds with consistent contact pressure.

To meet these requirements, the PR2 uses a wheel guided and spring supported current collector that enables fast and efficient material transport while ensuring stable power transfer. This supports intensive usage cycles and delivers maximum uptime in demanding intralogistics operations.

The PR2 system builds on the strengths of our open conductor bar portfolio, offering flexible configurations that can be adapted to any shuttle track layout. For PR2, this includes the use of specially designed funnels that ensure precise collector alignment during transitions between paths, supporting reliable operation in multi‑directional shuttle layouts.

Shuttle system operating in intralogistics with horizontal transport paths

Shuttle Systems

Shuttle systems are widely used in intralogistics for high-speed storage and order picking. They enable efficient use of space and support continuous material flow in automated warehouses. With high reliability and 24/7 availability, shuttles ensure a efficient material flow—ideal for e-commerce, production environments, and fulfillment operations that demand top performance.

The AKAPP PR2 conductor bar system offers a low-profile and efficient power supply tailored to these conditions. Its compact design supports reliable power transmission in installations with limited space.

Mini-load ‘Light’ Cranes

Mini-load ‘light’ cranes play a vital role in modern intralogistics, enabling fast and automated storage and retrieval of small parts with outstanding precision and space efficiency. As these machines become faster, more compact, and significantly lighter, the need for equally efficient and lightweight power supply solutions continues to rise.

AKAPP’s 2-pole conductor bar system supports these developments with a compact and reliable power supply specifically suited to new-generation mini-load cranes. Its slim profile allows easy integration into narrow crane structures, ensuring stable operation.

Transfer Cars

Transfer cars play an important role in modern intralogistics, enabling fast and reliable cross-aisle transport to keep material flows running efficiently. Because transfer cars operate with frequent starts, stops, and lateral movements, a conductor bar system such as PR2 offers a stable and space-efficient power supply that supports continuous operation. Its compact profile ensures reliable power transmission even in installations with very limited mounting space.

When additional IP protection is required, we recommend using Akapp Multiconductor systems.
