CR23
SAFETY AND COMFORT
ON EVERY STEP
Lifting and carrying people up and down stairs on a daily basis is sometimes the greatest physical challenge for rescue and ambulance personnel. It is not uncommon for this heavy work to lead to acute or permanent back disorders. The tendency towards higher body weights and steadily increasing numbers of missions requires solutions for a sustainable physical relief for the rescue service personnel. In response to this, AAT has developed the mobile stair climber CR23.
WITH THE CR23
BENEFIT TO THE MAXIMUM

Safe storage in the vehicle
Crash tested according to DIN EN 1789:2007+A2:2014 (TÜV Rheinland) in folded and unfolded condition.
Automatic braking function
The automatic braking function when descending is part of our safety concept.
Usable on spiral staircases
The CR23 offers high maneuverability even on spiral or narrow staircases.

Unique ergonomics
Our control unit has been specially designed to provide you with maximum comfort during the climbing process - whether climbing up or down the stairs. With ease, you can use the control unit to activate or deactivate the stair climber, adjust the speed continuously or decide whether you want to go up or down the stairs.
The control handle also features a safety chip which ensures that the stair climber is only used by authorized persons. Therefore, you can always be sure that your stair climber remains in safe hands, even if you temporarily leave it in the hallway of an apartment building, at the doctor's office or in another public location.
In service for your safety
The extendable support handle offers the possibility of guiding the CR23 when climbing down the stairs. In addition, the second person, who only acts as a safeguard, provides the patient with a comfortable and safe feeling.
The stair climber has an integrated LED light on the lower part of the drive unit. This function provides optimum illumination of the steps even in poor lighting conditions. This is particularly important in bigger staircases with an automatic light control system.
One of the most outstanding features of our safety concept is the automatic braking function when descending. This innovative technology prevents the stair climber from being pushed too far over the edge of the stairs. The brakes activate on every step, ensuring optimum safety every time the stair climber is used.


Intelligent equipment
The CR23 is powered by a rechargeable battery pack, which can be loaded via the included charger. Depending on the person weight, the battery charge is sufficient for up to approx. 20 floors. In order for you to be more flexible, we offer you the possibility to charge the battery pack directly in the vehicle. A voltage converter is available as an accessory for both cars (12 V) and trucks (24 V).
In addition, the stair climber CR23 is equipped serially with a MAG code charging socket. This separate charging socket on the left side of the housing enables direct charging of the stair climber CR23 incl. inserted battery pack in the vehicle. This requires a special charger with a special MAG code plug.
The stair climber CR23 is equipped with our revolutionary Comfort Step. For you as a user, this results in an extremely comfortable and low-vibration climbing process. It works in single step mode as well as in the permanent climbing mode.
Innovative mounting systems
The CR23 is a stair climber with a foldable, integrated seat. It can be folded in just a few steps and is easy to stow thanks to its compact dimensions.
Specially developed mounting systems provide the basis for loading the CR23 securely in the vehicle. These mounting systems in combination with the CR23 are crash tested according to DIN EN 1789:2007+A2:2014 .
A mounting system with special AAT floor rail is required for loading in the unfolded condition. It is locked in a "heavy-duty" allsafe airline rail. We will be happy to inform you about other mounting systems such as our floor mounting.
