PNEUMATIC CYLINDERS
Pneumatic cylinders are operation elements for door opening and closing by compressed air. Pneumatic cylinders are divided into three basic groups: linear cylinders, rotary cylinders, and rotary cylinders fitted with the lifting to the door wedges.

TR - pneumatic linear cylinders 
WH - pneumatic linear cylinders  
OK  - rotary pneumatic cylinders  
OD - rotary pneumatic cylinders with the lifting

KDU - ball valve  
B9356 - control valve  

DOOR LEAF LOCKING
Locks the door leaf locking in closed position.

ZAM - door locks are used for linear cylinders and OK cylinder blocking  
K - wedges are used for OD cylinder blocking

ACCESSORIES
For door leaf fastening to the vehicle frame.

Arms, bars, tension system of OD cylinder, covers
