Characteristics of the vehicle:
A pasoval drum. At the end of the low and high speeds the drum is fitted with a pneumatic ventilation coupling. The tape brake of the drum shall be forced water cooled. Disc brake flange applies forced water cooling and air cooling.
The surface of the brake drum and brake flange is hardened and has a high wear resistance, long service life.
All bearings – rolling bearing, bearing material – alloy steel.
The chain USES forced lubrication.
Chain wheel tooth profile through intermediate frequency hardening. All switching couplings are couplings with an evolven cord.
Main brake band and disc. Auxiliary brake – electromagnetic vihear or eathon brake.
