3 Description and Technical Data
3.1Performance Description
Tray transport trolleys are intended for transportation and distribution of meals in the field of the food ser-
vice industry, large-scale kitchens and catering establishments. They hold up prepared meals on GN or EN
trays.
Thanks to their special design, welded tray transport trolleys meet the highest hygiene standards. The
hinged doors can be locked at approx. 270° to allow an easy and thorough cleaning of the interior using a
pressure washer or a hose.
Additionally, tray transport trolleys with passive cooling have a special middle wall which enables receiving
cold storage plates. The usage of cold storage plates allows to keep meals cool for up to four hours.
3.2 Proper Use
The tray transport trolley is intended for receiving GN and EN trays. It serves for hygienic and economic
transportation of prepared trays with warm or cold meals.
Transport of living beings, heavy and sharp-edged items, loose crockery items beyond the tray or stacks of
crockery items is not permitted.
Tray transport trolleys that are coupled to induction docking stations may be loaded only with crockery and
trays which are suitable for induction heating and released by HUPFER®.
Tray transport trolleys with a circumferential gallery may transport objects that have a firm base and are
placed over the non-slip pad to protect against falling down (such as crockery, cutlery and napkins in suita-
ble transport containers or on trays). The top of the trolley may be loaded with up to 55 lbs (25 kg).
Proper use includes observing specified procedures, compliance with the technical specifications and use
of supplied or optional original accessories.
Any other use of the appliance is considered as unintended use.
3.3 Improper Use
Tray transport trolleys without a circumferential gallery are not intended to be used as a storing surface for
items.
In no case may people sit down or stand on or inside the appliance.
Tray transport trolleys that are coupled to induction docking stations may not be loaded with metal crock-
ery, metal cutlery or meals covered with metal foil.
Tray transport trolleys may be moved only with closed doors and only with the hands on the push bars.
Gallery bars are not suitable and can be damaged.
The manufacturer and suppliers are not liable for any consequential damage resulting from unintended
use. No liability is assumed and no warranty claims can be submitted for damages caused by improper
use.

3.4.3 Standard Equipment
The tray transport trolley is entirely made of stainless steel, benefits from double-walled insulation and has
a welded interior.
The side walls are equipped with seamlessly deep-drawn beads at a distance of 4.5" (115 mm) (optionally
also 3.7" (95 mm) or 4.1" (105 mm)).
The side walls of the tray transport trolleys can be equipped with an embossed tilt protection when they are
not used together with inductive docking stations.
Smooth surfaces and the seamless fabrication of the side and middle walls enable an easy cleaning of the
interior. The middle walls can be removed for a thorough cleaning of the appliance.
You can swing the hinged doors to an angle of approx. 270° and lock them. The 2-point locking mechanism
safely locks the doors during transportation.
The design with vertical push bars in the corners of the trolleys ensures that they can easily be manoeu-
vred with the doors open or closed without any difficulty, even when fully loaded.
The corrosion-resistant swivel casters with total locks and fixed casters made of stainless steel ensure an
optimal movement and manoeuvrability of the tray transport trolley.
The lower peripheral frame made of shock-resistant plastic offers an optimal bumper and it is disconnected
in the middle on the right and left sides for the optional installation of the coupling and drawbar.
3.4.4 Equipment and Optional Accessories
You can install and fit the tray transport trolleys with optional accessories in various ways.
§Gallery:
The gallery and a non-slip pad make it possible to use the top of the trolley as an additional and se-
cure storage surface. The top of the trolley may be loaded with up to 55 lbs (25 kg).
§Central total brake:
The optional central total brake provides a firm hold during operation and standby mode. One single
foot control locks the swivel casters of the tray transport trolley.
§Casters that can only roll in one direction (Rifix):
Casters fitted with Rifix can be fixed to roll in one direction only. This significantly facilitates the di-
rectional stability, e.g., during traction operation.
§Coupling and drawbar:
For the connection of several tray transport trolleys for traction operation. The simple version is also
available in combination with casters that are movable in only one direction. The second option with
friction damping enables the directional stability during traction operation even in tight bends.
§Shelf for beverage containers with lengthwise or crosswise insertion.
§Stacking basket, stainless steel, plastic-coated, lengthwise insertion.
§Card holder
§Connecting components for induction docking stations.
§Trays:
Tray transport trolleys are intended for the use of EN trays and GN trays. Suitable systems are e.g
HUPFER®SDS trays.
§Induction crockery
Generally, all standard induction crockery can be used in combination with tray transport trolleys
and induction docking stations. Since the manufacturers sometimes use different coatings, the pow-
er consumption is always dependent from the used crockery when the device setting is identical.
When it deviates from the standard then a fine tuning between the device and the crockery is al-
ways necessary. This fine tuning must be done by the manufacturer or the service technicians au-
thorized by the manufacturer.
On request, recommendations for induction crockery are made available. Isolating covers for the
main course dishes (deep plate Ø 9.4" to 10.2" (240 to 260 mm) and stew bowls Ø 6.7" to 7.5" (170
to 190 mm) are also available as a special accessory.
