• Kaiser believes its Mega Combi is the largest sewer cleanser made. It is based on an Australian-made RFW 8x8 truck chassis and trailer with three hydraulically-driven axles.
Both units have Detroit Diesel Series 60 engines; 330kW (442hp) in the front with Allison automatic transmission and 260kW (342hp) on the trailer.
Kaiser bodied the 46-tonne GIW, 16m-long drawbar rig at its Leichtenstein plant for Brisbane City Council to clear heavily silted sewers in areas where fresh water is scarce. The twin-pump jetting system delivers 6801it/min at 135bar with water recycling.
Its Kaiser KWP6000 liquid ring vacuum pump produces up to 6,300m3/hour and has the capacity to draw heavy silt up from 30m down into a 14,000-litre stainlesssteel tank with hydraulic divider door.
Noise levels are 75dB(A) at 7.0m Slow-moving pumps and screens with pneumatic scrapers help recycle the sewer water for reuse through the jetting pump.
Other equipment includes min hydraulically-driven hosereels and extending/ slewing boom.
