In the sheet-metal processing industry, the flexible supply of materials having different formats and thicknesses is the prerequisite for process optimization.

The STOPA TOWER Flex can achieve this task even in confined spaces. Initially, the system can be installed as a dual tower, or as a single tower with the option of subsequent retrofitting. With the compact design of the shelf tower, an economical system with perfect balance between storage capacity and floor space is created. To utilize the maximum available ceiling height, the stacking height of the shelf towers can be adjusted (also available with its own cladding for building-support).

Depending upon your needs, by using different loading and unloading stations, several production machines can be linked to one STOPA TOWER Flex.

According to customer needs, transport carts and scissors lifts (also in combination) can enter and exit the stations at all openings (on the face and longitudinal sides). Up to 11 stations are possible.

Supplying materials to defined work positions

So-called deposition frames are used to bring system pallets with raw sheet metal or finished parts to predefined work positions.

They can be combined with any desired cart – provided it is equipped with a lifting unit. The use of deposition frames allows the needed material to be brought to a predefined height without long-term blocking of the cart. This makes it possible to serve even several deposition frames in series with just a single lifting cart. This permits parallel working at several different positions, leading to the efficient utilization of storage capacity and shorter cycle times.

They are also suitable for manual stations, insofar as deposition frames can be used outside of a machine’s automatic zone or outside of the storage facility and because they are available in predefined ergonomic heights.


  • Different heights possible
  • Only in combination with scissor lifting table / WIRELESS CART
  • Positionable loading surfaces possible
  • Several deposition frames can be used in series


Ideal helper for unpacking raw sheet metal and removing from pallets

The STOPA Unpacking Table is the ideal helper, and accelerates the process of simply unpacking stacks of raw sheet metal and/or of separating the stacks and removing them from the carrier pallets (which are usually made of wood).

The positionable stamp carts on the unpacking table and its ergonomic height enable optimal placement of the stack of raw sheet metal onto the stamps. At the same time, the wooden pallets are suspended freely in the air and are held to the stack only by the packaging. When this packaging is then removed, the wooden pallets fall down onto the table. The raw sheet metal can now be simply brought to the incoming goods station using a forklift or crane.


  • For separating raw sheet metal and wooden pallet
  • Solid table with freely traveling stamp frame
  • Available for all standard sheet formats


Parallel loading and unloading of machines

As a rule, the double cart is used for the parallel loading and unloading of sheet metal processing machines. It thus consists of two components: the lower cart and the upper cart. This leads to shorter cycle times and the efficient use of the machine and/or the storage system and of any downstream processes. The lower cart can be designed as a transport cart with a fixed height, or as a Scissor Lifting Table (SLT).


  • Consists of a lower cart and an upper cart
  • Standard model is two transport cars (upper / lower cart) with a fixed height
  • Lower cart as scissor lifting table possible
  • Parallel loading and unloading
  • Quick cycle times
  • Low loss of space
  • Can be used both for supplying machines with raw sheet metal and for the return storage of finished parts
  • Available for all standard sheet formats
  • Suitable for system pallets and EPAL Carriers
  • Entry / exit on the face side possible
  • Both dead-man mode and automatic operation


Accessory for system pallets to store small parts

As a rule, floor plates are used to store small parts (which would normally fall through the pallet tubes) and also grid boxes or wooden pallets. For this reason, the pallets are available in several different models.


  • Variant of the normal floor plate
  • Can be lifted onto the incoming goods cart by stamp
  • Corresponding gaps for forklift tines at the bottom
  • Can be removed by forklift and employed independent of the storage facility


  • Variant of the normal floor plate
  • Centering on the top suitable for EUR-Pallet or grid box
