Peculiarities of Braking System

There are two types of braking system:

  • Parking brake is activated using accumulators of brake chambers. It is used as a backup. It is activated using a hand-operated pneumatic valve that is a disconnect-type valve and located in the rear part of the vehicle;
  • Standard braking system is activated by a foot brake. It consists of the relay and disconnecting valves, trunk filters, and air dispensers as well as there are two coupling heads. In case of failure in the system of pipelines or air hose, the air will be released from the system, causing a sharp drop of general pressure, and, as a result, the brake chamber is activated. The unit is equipped with two air cylinders with a total capacity of 160 litres.

The height of the platform sideboards is 4 cm. There are two removable and one back. There are wideners that can increase the platform to 350 cm.

The undercarriage is made of three parts on the air suspension manufactured by VESTT. The pneumatic tubed tires with the parameters of 235/75R17,5 are used having the load index of 140/143 J.
