GRUNDOBURST400S
• For pressure and sewage pipes ND 50-ND 250 up to approx. 100 m length (depending on method)
• For installation in manholes up to ≥ ND 1000 and in small pits
• Bursting rig length only 60 cm
• Bursting rod effective length in manhole: 470 mm
• Relatively simple operation inside the manhole
• No civil engineering works when working from manhole to manhole
• High level of working safety
• Installation of short pipes in manholes with Burstfix, see page 12 (Burstfix is available for all GRUNDOBURST models)
