Maintenance
The two part chassis is of the centre pivot articulating type and
is of a design which enables both front and rear axles to be
attached directly to the chassis members.
The front and rear frames are connected in the middle by a
vertical pivot in spherical bearings and a horizontal link, which
connects between the spherical bearing of the vertical pivot and
an additional spherical bearing located in the rear frame.
Lubrication of the three bearings in the assembly is important
and should be carried out weekly in accordance with the
schedule in the Maintenance section.
Chassis
This arrangement is illustrated in the diagram below and shows
full movement of the chassis in both horizontal and vertical
