PR7 for AS/RS and warehouse automation

7‑pole electrical power supply systems are commonly used in AS/RS and warehouse automation for larger cranes and machines. In these applications, the AKAPP Pro‑Ductor PR7 system is often configured with two sets of three phases plus ground (or neutral) to deliver the required power.

Where a single three‑phase plus ground (or neutral) supply is sufficient, the 7‑pole PR7 conductor rail profile is also used for systems that require additional conductors for control/signaling. Thanks to the five different copper conductor cross‑sections available, the system can be precisely tailored to meet specific application requirements.

Key Features of the PR7

7‑pole system, up to 400 A
Travel speed up to 500m/min
Continuous copper conductors for minimal wear
Wheel guided /spring support current collector
Suitable for horizontal and vertical operation
Typical applications: Stacker/pallet (RGB) cranes, miniload (AKL) cranes, transfer cars

AS/RS warehouse shuttle system with Akapp Pro-Ductor conductor bar

Storage and Retrieval Cranes (AS/RS)

Storage and retrieval cranes are used in high bay automated warehouses for the handling of palletized or box size loads. As these automated storage systems depend on 24h operation power demand requires stable and 24h availability at the lowest total cost of ownership. Three-phase power is typically used to support drive and lifting systems.

The Akapp 7-pole conductor bar system PR7 provides reliable power supply for these applications, enabling stable energy transmission over long travel distances. And minimizing wear/maintenance.

Stacker/pallet (RGB) cranes

Stacker cranes are used in automated warehouses for the storage and retrieval of palletized goods and heavy loads. Operating over long travel distances and handling significant loads, these systems require a stable and continuous power supply to support reliable movement and lifting operations.

The Akapp PR7 conductor bar system is developed for larger warehouse automation applications. Its 7-pole configuration allows power and additional control signals to be combined in a single system, supporting efficient operation in high-capacity AS/RS installations.

Miniload (AKL) cranes

Miniload cranes are used in automated warehouse systems to store and retrieve totes, trays, and other small-load carriers. As warehouse systems become larger and more automated, reliable power supply and control functions are essential for efficient operation.

The Akapp PR7 conductor bar system is well suited for these applications. Its 7-pole configuration supports both power transmission and additional control functions, helping ensure reliable operation in automated warehouse environments.

Transfer cars

Transfer cars are used to transport materials and products between production areas, storage locations, and transfer points. Often operating over long travel distances and carrying heavy loads, these systems require a reliable power supply to maintain efficient material flow.

The Akapp PR7 conductor bar system is well suited for these applications. Its 7-pole configuration provides a dependable power supply for larger transfer car systems, supporting reliable operation throughout the transport process.
