Mecalux develops a warehouse type that suits all Renfe maintenance centres

Automated storage for boxes and pallets and cantilever racking in the Renfe "warehouse model"


Mecalux, Renfe's regular outfitter, has designed a warehouse that is viable for any of the railway company's maintenance centres. The solution was to combine a miniload warehouse for boxes, an automated pallet racking warehouse and a warehouse with cantilever racking allocated to bulky items. Everything is controlled by the Mecalux Easy WMS warehouse management system.

Automated miniload warehouse

It is an ideal solution for storing small sized spare parts in 600 x 400 mm plastic boxes (euroboxes). A stacker crane is responsible for transporting the boxes between order prep stations and locations in the single-deep pallet racking installed on both sides of the circulation aisle.

The picking stations, located at one end of the aisle, allow quick and easy access to the product that is inside the boxes. These are automatically moved to their positions by following the sequence indicated by the warehouse management system. Product replenishment is carried out from the same station where picking functions are performed. So that replenishment tasks do not hinder the preparation of orders, the so-called off-peak hours are utilised, i.e., when normally there is less prep work.

Automated warehouse for pallets

Already palletised products are deposited by handling forklifts in an automatic checkpoint that monitors the status of the pallets, its dimensions and weight.

Order preparation can also be carried out from the pallet itself, which is automatically sent to the output conveyor, then picked up by the forklift (pallets with a single product). Most commonly the pallet is sent directly to the manual preparation station, where the operator removes the product. Then the pallet is transported to its new location on the racks.

Warehouse for bulky parts

This warehouse was reserved for over-sized goods that cannot be deposited on pallets without them overflowing the load. As a solution for the wide variety of product dimensions and weights managed by Renfe, heavy-duty cantilever racks were installed. In this type of racking, the unit loads rest on the cantilever arms that can store everything from metal profiles to large pallets without losing capacity.

In order to handle products of that size within an aisle of limited proportions, they were supplied with side-loading reach trucks that are able to work both quickly and safely.

Warehouse management: the Easy WMS

All management of the different warehouse areas depends on the Easy WMS warehouse management system by Mecalux designed to be used in both traditional and automated warehouses, optimising all movements, processes and operations.

This powerful software works via different parametrisable rules and surveys the distinct operations that are carried out in a warehouse; from product input to dispatch, passing through stock controls and order preparation.

Automatic movements performed by stacker cranes and the main conveyors are also governed by the Easy WMS, through the Mecalux Galileo control program.

The Easy WMS warehouse management system and the central management system (ERP) are in permanent communication to facilitate the remainder of the operations that take place outside the warehouse, essential to any company.
