Our largest LUMBERJACK® is the LJ700. The power from the large turbine together with the weight of the cutter cut the most severe roots from 400 mm (16”) up to 900 mm (36”) pipes. Special solutions with aluminium expander plates are available. Many customers use this solution for removal of mineral and chemical deposits and tuberculation The LJ700 needs minimum 350 LPM (90 US GPM) and for larger pipes the water flow rate needs exceed 400 LPM (105 US GPM). LJ700 handles pressures up to 150 Bar (2200 PSI), at the cutter.
The skid technology for LUMBERJACK®LJ700 is an adjustable skid with runners. Correct pipe size is adjusted through distance plates.
The standard cutting link comes with a welded outer link. For longer service lifetime hardox reinforced links are available.
