For lifting the centre or rear axle or, where there is
limited space available, it is possible to use the
central lift system. The centre lift is fitted on the
chassis centre line. The top fixing is mounted to a
chassis crossmember and the lower fixing is
clamped to the axle beam.
The lifting bag forces must be counteracted by an
adequately dimensioned crossmember.
