20-year guarantee – The TwenTower system patent has been in existence since 1996.
TwenTower® storemaster® Original from 1996 – an investment for generations – featuring self-supporting pull-out rail walls (storemaster® innovation from 2024).
 
The storemaster® – functional safety for swivelling pull-out roller side panels:
The roller-flange guides on the running surfaces of the rails reliably secure the drawers against falling out when subjected to additional lateral forces, automatically locking them in place without the need for any additional measures that do not comply with BG regulations (storemaster® innovation from 2015). Strong magnets automatically secure the extended pull-out roller side panels in their 90° position, without the need for BG-non-compliant mechanical or manual locking mechanisms.
The storemaster® – smooth running:
Each pull-out is mounted on 8 special low-friction ball bearings on chromated solid steel flanged wheels (no lightweight sheet metal casing rollers or ball bearingsas wheels) with double axle bearings, running safely and without jamming on hot-dip galvanised (10 times more abrasion-resistant than painted surfaces), smooth running rails without dirt pockets, as there are no raised or recessed edges. Perfect fall protection with automatic function in accordance with UVV for the swivelling version. Special heavy-duty precision block hinges with permanent lubrication ensure, in the case of swivelling pull-out roller side panels, a permanently step-free transition from the rail into the pull-out area – durable and maintenance-free.
Occupational safety and accident prevention (health and safety) in accordance with internationally applicable standards:
storemaster® meets the following UVV occupational safety requirements, which cannot be rectified through subsequent modifications and without which commissioning the product would permanently jeopardise BG insurance cover: elimination of human error through the omission of operating safety devices.
TwenTower® Unique Selling Points
 

Convenient batch storage rather than sheet by sheet using the patented PalEx depalletiser, thanks to the storemaster® drawer-depth-web-frame construction (invented in 1995) with a slip-proof sheet metal package embedding system.
TwenTower® heavy-duty drawer systems are suitable for all storage and stowage variants => optional switching between stowage without wooden pallets and stowage including wooden pallets, and vice versa.
Safety devices are automatically activated during operation of the system in accordance with UVV regulations and are therefore not subject to arbitrary manual operation, i.e. operation that could be overlooked.
Automatic locking of the swivelled-out roller rail panels at a precise 90° (adjustable) via strong magnetic adhesion – this release automatically when swivelling back in, without the need for locking pins etc.
The storemaster® pull-out technology allows installation and operation on any type of floor surface, as well as on warped and/or uneven surfaces with a gradient, without the need for a foundation slab. The swing-out pull-out rail panels (doors) do not come into contact with the floor; heated floors and those with sensitive coatings remain undamaged.
100%-type UVV drawer fall protection via a patented automatic flange-groove forced-guidance system (DBGM) without the need for arbitrary (and potentially overlooked) mechanical operation by the operator.
Automatic, self-releasing locking mechanisms secure the resting and working positions against unintentional movement of the drawers without the need for manual operation of mechanical locks.
Runners without dirt pockets, made from dimensionally stable solid steel (no folded sheet metal), abrasion-resistant and hot-dip galvanised, running surfaces ground, welded to the frame (not bolted) to ensure a permanently step-free transition between the fixed and swivel rail sections via a mitred joint.
The patented shaped-steel upright framework in a torsion-resistant L-shaped upright frame construction (DBGM) – not a portal! – with welded foot beam load distributors (storemaster® trademark) alone ensures the long-term verticality of the support structure columns, guaranteeing the unlimited, unrestricted functionality of the system without diagonal cross-bracing, which is what enables the structural stability verification for both single-sided and double-sided designs without cross-bracing.
High-load-bearing, permanently lubricated heavy-duty block hinges for permanent fixation of the swing-out panels at their height position.
Precision twin-axle wheel suspension for smooth, wobble-free running performance at all times.
Particularly low pull-out force even with heavy drawer loads, without the need for aids (crank, etc.).
Patented Servo pull-out spring facilitates the extension of heavy-duty drawers.
Drawers can be very easily removed individually from the system to adjust the usable height.
Heavy-duty, solid steel flanged rollers, chromated, with double ball bearings.
Storage density of up to 25 drawers at an extension height of approx. 2 m.
Combinable sheet metal and bar material storage units with plug-in compartment dividers.
Drawer extension > 100 %.
UVV-compliant anti-slip device for double-sided sheet metal removal.
OverheadTop add-on block can be retrofitted without the need for subsequent adjustments.
OverheadTop add-on block with cantilevered storage levels for easier insertion of forklift forks, height-adjustable in 75 mm increments, operable from both sides – optional for cassette storage.
Electrification up to 10 t / pull-out storage level – max. 13 drawers (storemaster® patent).
System with swivelling roller-track pull-out walls, pre-assembled and ready for operation.
Operational and functional safety in accordance with the guidelines of the RAL-RG 614 Quality Association.
20-year functional guarantee.
TwenTower® extension to the MasterTower® using a statically structurally secured professional steel construction with integrated crane column without auxiliary support – crane approval by an expert in accordance with DGUV Rule
108-007 and DIN EN 15635 – crane connection can be offset on either side.
