The mobile blood donation tool is manufactured as a cabin with a volume expanding 1 meter to the right and left. Cab expansion is hydraulically controlled. - The cabinet is insulated against heat, water and dust. The cabin walls, the base of the cab and the cabin doors are made of glass-reinforced polyester material (FRP) that does not advance flame and extinguishes itself. The panels are filled with 4 cm thickness and 32 density density foam material. Panel walls are produced with wet technology. The walls are mono-block. Walls and frame are supported by box profiles. - Cab floor covering is made of 18 mm polywood material. It is covered with 2 mm epoxy or PVC floor covering to provide water and dust insulation. - There are entrance and exit doors equipped with handrails in front and behind the cabin. In the design, the emergency exit scenario is taken into account and all doors must be locked from both inside and outside. The gas piston system is added so that all doors can be self-closing.
