BHS - 博得高速系統 Drive  The drive of the single-panel Bode plug sliding door basically consists of a roller carriage which runs along a guide tube and securely connected to the door panel via a counter tie rod system. The counter tie rod system produces the swivel-out movement of the door which is controlled via a guide channel.  The complete drive is mounted on a base plate and preset. This allows the drive to be replaced quickly and simplifies fine adjustment.
