3.2.4 PARKING BRAKE

The parking brake is for immobilising trailer while standing motionless. The brake crank
mechanism, located on the left side of the frame, is connected with the axle expander levers
using a steel cable. Rotation of the crank increases tension of the steel cable. Expander arms
exert pressure on brake shoes and cause the axle to brake. Prior to moving off, handbrake
must be released - steel cable must hang loose.

3.2.5 ELECTRIC LIGHTING SYSTEM

The trailer's electrical system is designed for supplying from direct current source of 12 V.
Connection of the trailer's electrical system with the tractor should be made through an
appropriate connection lead delivered as standard equipment of the machine.
Arrangement of electrical system components and connection diagram of the connection
socket are shown in figures (3.13) and (3.14)
