Adjusting the length of the rail
hook
Make sure that the rail hook has the correct length
for the distance between the rail (or auxiliary device)
and the tank car. After installation, dimension X
between the washer (3) and tube (7) must be
approximately 40–50 mm.
To adjust the distance, proceed as follows:
Measure the distance from the cable lug to the
attachment point on the rail or auxiliary device.
Subtract dimension X from this measured
distance. This is the nose - hook dimension to
be set.
Undo the two hexagon screws (5) using a
size 13 open-ended spanner.
Adjust the hook (4) to get the correct dimension.
Tighten the two hexagon screws (5) to a torque
of 4 Nm.
Tensioning the nose
To tension the nose of the VZ 10, proceed as
follows:
Using the compressed air hose (10), subject the
cylinder to pressure between 4.5 bar and 9 bar.
Press the push rod (15) back and turn the nose
(14) at right angles to the longitudinal axis of the
rail hook.
The push rod tensions the nose.
To tension the nose of the VZ 20, proceed as
follows:
Press the push rod (15) back and turn the nose
(14) at right angles to the longitudinal axis of the
rail hook.
The push rod tensions the nose.
