The SEZAM drive is installed on the door in the passenger compartment. Opening and closing is carried out by means of a worm gear from the gearbox to the sprocket, which engages with the rail.

A lock drive is mounted inside the door, which helps to reduce the wear of the carriage rollers and provides a more reliable locking of the door.

Installation Manual

The drive device is quite simple. It is based on the time-tested Bosch gearmotor, a pillow block bearing the main load from door movement, an asterisk and a safety rail made of durable polyamide with closed teeth.

The closed teeth of the staff reduces the risk of clothing and other objects getting into them, and also gives an aesthetic appearance. For unforeseen situations, the drive has an emergency door open lever, with which you can easily open the door manually from the inside of the bus. The drive frame has a damper spring, which serves to mitigate the impact of the drive on the rail stop when the door is opened. The design of the damper spring allows you to open the door for the entire length of the rail. Especially for those cases when it is necessary to increase the width of the door opening, a SEZAM drive with a vertical arrangement of a gear motor was developed. Installing such a drive allows you to increase the width of the door opening by 2 inches.
