FIG. 3.6

Hydraulic brake construction and system diagram

(1) hydraulic cylinder, (2) hydraulic quick coupler, (3) hydraulic socket, (4) information decal

Three-step brake force regulator (2)- figure (3.7), adjusts braking force depending on setting.

Switching to a suitable working mode is done manually by machine operator using the lever

(4) prior to moving off. Three working positions are available: A - "no load”, B - "half load”

and C - "full load”.

For systems with automatic regulator, braking force depends on trailer load.
