The Grundowinch plays a key roll in pipebursting operations.
The constant tension, variable speed Grundowinch makes adjustments
for conditions that affect line speed during operation,
providing constant and consistent pulling force and preventing
slack from developing in the line. Twin capstans protect
the cable and cable drum from extreme stress levels. The
Grundowinch essentially guides the tool through the host
pipe.
Several factors dictate whether pipebursting is appropriate
for the rehabilitation of a failed line. These considerations
include host pipe material, diameter, condition, depth,
length, new pipe diameter, soil conditions, peripheral utilities
and service connections. The Grundocrack can be used to
burst fracturable pipes (cast iron, clay, concrete, RCP,
ABS and some plastics) with diameters between 4 and 54 inches.
