Expansion set KASRO self-propelled unit DN800

The expansion up to DN800 is needed for using the KASRO self-propelled unit for pipes in the diameter range of greater than DN600 to DN800. To connect the working robot and the self-propelled unit to each other, the 130 mm long spacer needs to be mounted with the fork head and strap between the working robot and the self-propelled unit. For the diameter range DN700 to DN800, attachment mod- ules with pneumatic tyres are mounted on the KASRO self-propelled unit. The assembly steps for these attachment modules are the same as for the attachment modules for DN400-DN450 and DN500-DN600 of the KASRO self-propelled unit. There are two clamping half-shells on each module for better support that are removed before the assembly and re-attached after the assembly on the self-propelled unit's gearbox.
