Grundoburst shows pulling power

摘要

A TT-UK Grundoburst 400S was used recently as a pulling device to slipline a 21" cast iron water pipe for a new replacement 450mm SDR17 PE pipe. To speed up pipe installation times, the longer than usual Quick-Lock ladder type push / pull rods were used on the night work operation. Due to the highly sensitive London inner-city location, the Grundoburst's Super silenced hydraulic power pack kept noise to a minimum and was greatly appreciated by the local residents. Pushing in the 176m of QuickLock rods commenced at 7.30pm and was completed by 10.30pm. Pull back through the cast iron water main commenced just after midnight and the new PE pipe arrived unimpaired into the docking frame within four hours.
