3 Description and Technical Data
3.1 Performance Description
Tray dispensers are provided for the transport and storage of different trays in large-scale catering estab-
lishments and in the food service industry. If necessary, there are various models available:
Models of the type OTA are preferably used in areas of customer self-service counters, bistros and cafete-
rias. Furthermore, they can be used for the storage of trays on food distribution belts and in sculleries if there
is no automatic stacking.
Models of the type OTA/S are suitable for the stacking of trays at crockery return conveyors, also in connec-
tion with a stacking device. The trays are placed in the longitudinal direction and are held in place by the
sideways tray guide rails. The stacking area is adjustable in length and width to different tray dimensions.
Open basket dispensers of the type OTA/U-BW are suitable for the automatic stacking of trays in longitudinal
or transverse direction at dishwashers. The stacking area is adjustable in length and width to different tray
dimensions.
Models of the type OTA-E/BA-4xGN are also used in areas of customer self-service bars, bistros and cafete-
rias. They do not only provide trays but also cutlery in GN containers with sneeze guard.
Models of type TAG are closed tray dispensers for a stack of EN or GN trays. They are preferably used as a
tray dispenser in the guest area of cafeterias, canteens, rest houses and bistros used. In contrast to open
tray dispensers, the tray column is guided on all sides above the entire height and can not be overturned.
Due to the closed side walls, the tray dispenser can store trays of different colours and formats without dis-
turbing the overall visual impression.
Models of the type TA are closed on the front side and are intended for two stacks of EN trays and GN trays.
Due to the high capacity, these models are ideal for the use on food distribution belts.
Besides the mobile tray dispensers, there is the model EBS-T intended for installation in worktops.
3.2 Intended Use
Tray dispensers are intended exclusively for transport and storage of trays ready for use.
Appliances of the type TAG have no compartment inner panelling. Therefore, universal trays, breakfast trays
and trapeze-shaped trays can not be inserted because of the smaller tray dimensions.
Appliances of the type TA are suitable only for EN and GN trays due to the half-open design. Other tray di-
mensions may not be used.
The intended use means the predetermined procedures, compliance with the indicated specifications and
use of the delivered or additionally available original accessories.
Any other use of the appliance is considered as unintended use.
3.3 Improper Use
It is not permitted to load the tray dispenser with other loads as given.
Tray dispensers are not intended to transport food.
In no case may people sit or stand on the appliance. Transport of persons is not permitted.
No liability is assumed and no warranty claims can be submitted for damages caused by improper use.

3.4.2 Appliance Description
Tray dispensers are executed in the self-supporting construction of stainless steel.
They accommodate trays on a spring-loaded stacking platform. Owing to the use of special springs, trays are
moved automatically and constantly over the entire lift upwards to a uniform dispensing height.
The ergonomically formed push bars with integrated bumper protect the operating staff against damages to
the hands. Corner bumpers on the rear protect the appliance against damages when transporting it.
The stacking platform of the models TA, TAG and EBS-T is removable and makes it possible to adjust the
springs as well as to clean the appliance easily.
3.4.3 Optional special accessories
The following parts can be applied as optional accessories for the movable tray dispenser:
Casters made of corrosion-resistant and maintenance-free plastic with a thread protection, a precision
ball bearing, Ø 4.92’’ (125 mm) with and without the total brakes, plate attachment
Holder for dispensing napkins (for OTA E/BA-4xGN)
The part numbers of the special accessories can be found in the spare parts catalogue and order lists avail-
able online.

sioning
4.1 Transport
ATTENTION Damages caused by improper transport
In the case of off-site transport in a vehicle such as a lorry, the appliances
should be secured properly. The total brakes are not sufficient as a transport
securing method.
If the appliances are not secured properly, there is a risk of damage to prop-
erty and persons caused by squashing.
During transport, secure all the individually standing appliances using corre-
sponding transport securing devices.
