Spring washers

Installation

The spring washers are supplied in the screwed in length. The lock nut is released and
the threaded rod unscrewed until the spring washers have an installation length of
approx. 780 mm.
Adjusting the spring washers
Important!
It must be possible to move the drawbar installation 300 mm upwards and
downwards from the horizontal position before the compression spring reaches
the limit of its travel.
Turn the adjusting nut to pre stress the compression spring until the drawbar installation
moves down approx. 300 mm from the horizontal position (measured at the drawbar eye)
and is held by the spring washers.
The drawbar is fixed in the horizontal position. The bogie connection point with the
installation length of 780 mm means the connection point of the support device is on
the lengthways strut of the drawbar.
Tip:
If a lifting force of approx. 40 kg at the towing eye is exceeded, the spring washers must
be readjusted.
Adjusting body
Caution:
Take care to position the spring washers correctly
