The Kardex Vertical Buffer Module is the best solution for fast-growing product ranges with limited storage space.

A scalable shelf system with a movable mast transports the bin and fits seamlessly into existing processes and building layouts.

How does the Vertical Buffer Module work?

Vertical Buffer Module LR 35 - Pick small parts quickly and efficiently

The LR 35 optimizes order picking performance of small parts and lightweight goods while guaranteeing accuracy and energy efficiency. Whether being used to supply a production line with a wide range of products; as buffer storage in the assembly area; or for picking slow-moving parts in the distribution warehouse, the LR 35 significantly improves productivity.


The Vertical Buffer Module is flexible and scalable. A station can consist of one or more units. The LR 35 easily integrates into existing processes and connects to different customer host-systems.


The LR 35 features ergonomic picking stations. This simplifies the picking process and improves overall working conditions. At each access opening, items tilt at a 20-degree angle while the goods-to-person principle delivers items directly to the operator, eliminating walk and search time.

Picking station

The turntable is the picking station’s key element. Tilted at a 20-degree angle, it is extremely ergonomic and easy to operate.


While the operator picks the order, the next bin or tray is prepared in the background and placed on the turntable’s rear shelf. As soon as the operator finishes picking one order, the turntable rotates 180-degree and the next bin is ready for picking.

Controlled single access opening

An administrator can control individual access to bins when needed. This is especially important when storing valuable tools and equipment.

Clearance control

The clearance control serves to protect sensitive and valuable items and reduce the risk of crash situations. Vertical light barriers monitor bin heights or overhanging goods in the aisle area.

In the event of an error, either the machinery does not start moving or its movement is interrupted and signals an error message.

Conveyor connection

The LR 35 easily connects to existing conveyor technology, either for manual storage and retrieval of bins and trays or for automatic operation and transfer to existing material flow.


The connection fits the end face, right, or left side. It is designed to constantly move bins to fill orders automatically and increase order picking performance. Also, replenishment can be done automatically.

Options for individual requirements

The greatest flexibility for every need

The Vertical Buffer Module is extremely flexible and offers a broad range of optional features. The modular design can be configured for a a diverse range of needs and integrates additional components at any stage, both before or after installation.

The LED pointer identifies the storage and retrieval positions at each picking station. It is a fixed, high-power LED light source that uses a controllable mirror to generate a spot of light projected directly into the compartment of a bin/tray. Without the need for a preset calibration, the light pinpoints the exact location for picking/putting.

The indicator located on the control panel display helps the operator identify storage locations in the bin/tray. This eliminates the need for a time-consuming search. The position indicator quickly and accurately guides the operator to the correct pick/put.

Located externally, LED lighting forms a canopy shape above the access openings to enhance visibility. This is especially helpful when warehouse lighting conditions are poor. The light can be switched on and off via the user display.

Based on individual fire protection requirements, it is possible to install gas nozzle pipes or sprinkler pipes for gas or water extinguishing systems in the area of the field reinforcements.

An externally located socket and various interfaces (2x USB, 1x Ethernet) are available for the picking station.

Innovative unit software with a capacitive touchscreen

For optimal performance in the warehouse

The software for the Vertical Buffer Module meets the highest standards: it offers a modern operating concept with a newly developed, capacitive touchscreen for even faster and more intuitive operation. The associated software is web-based and therefore works with a wide range of hardware.

Main operating features:

  • Modern and intuitive 
  • Capacitive touchscreen
  • Virtual keyboard
  • Optional connection to external keyboards or barcode scanners (USB)
  • Operating with new browsers is possible
  • Multilingual operations
