High density storage with Double Decker mobile shelving

Bruynzeel’s Double Decker mobile shelving is an ideal solution to maximise your archive storage if you have a building or storage facility with high ceilings. Compactus Double Decker provides four times the capacity of ordinary static storage. It offers the ultimate space optimisation for buildings with high ceilings, and costs less than the equivalent installation of mobile shelving across two floors.

A touch-sensitive electronic control panel makes operation of the system simple and user-friendly. The system’s “soft start and stop” mechanism allows the shelves to move safely and without vibration. Our sophisticated drive system moves at a constant speed regardless of load. Valuable and delicate objects remain perfectly in place. As a result, the Double Decker is proving an extremely popular choice for museum repositories, as well as for archive storage.

The two levels of shelving are connected by a unique wheel console with the uprights running the full height of the system. The weight of both levels is carried solely by the mobile units on the ground floor. Top and bottom bays move together in one smooth motion along the slots in the steel grid floor.

Clear sight lines between the two levels are maintained by the addition of a steel mesh mezzanine. Alternatively some customers prefer to specify wooden floor panels on the double decker mezzanine, which Bruynzeel will supply and fit on request.

The system can be equipped with integrated LED lighting, and additional innovative features such as Auto Air Circulation and fire alarm integration are available. The Double Decker mobile shelving system meets PD5454 standards including BS EN15095 electrical standard, required to meet PD5454.

Passive Safety

This safety feature locks the system as a default, forcing the user to check any open aisles for people and obstructions before operation. Passive safety is fitted as standard in the UK.

Motor Current Monitoring System (MCMS)

The Motor Current Monitoring System (MCMS) ensures safety for users of Double Decker mobile shelving. MCMS detects any increase in power usage caused by the motor driving against an obstruction, which will automatically cut the motor. Additional safety systems can be added to this system, such as photo cells and motion sensors. Using these features will ensure the units stop immediately in the event of a person being detected in an open aisle.
