SECTION 3

3.4

The rear part of the frame has a rear protection (4) - figure (3.2), a trailer lighting assembly

attached to the light support beam (7), and a rear hitch (5).

The trailer suspension consists of two steering axles (2) and one fixed axle (1), which are

attached to taper leaf springs with U-bolts. The springs are connected with rocker arm. Axles

are made from square bars terminated with a pin, where wheel hubs are mounted on taper

bearings. The wheels are single and equipped with shoe brakes activated by mechanical

cam expanders.
