General
A series of UNICORN slurry pipe jacking machines are capable
of handing pipe sizes(I.D.) from450mm to 2,600mm and of excavating through
even boulder, soft rock, medium hard rock, and hard rock layers which
has so far been impracticable with conventional machines. By simply changing
its cutter disc, the machine can be applied to the pipe jacking in the
ordinary soil, hard soil, and cobble gravel layers as well.
Crushing mechanism
The machine adopts a two-stage crushing mechanism; that
is, the primary crushing is performed with roller bits installed on the
cutter disk that rotates at a large torque and the secondary crushing
is performed with a robust cone crusher consisting of a mantle and cone
cabling.
@
1. Powerful crushers The primary and secondary crushing mechanisms that are driven by a large torque power are rrovided.
2. Greater applicability With a variety of cutter disks available, the machine can be used for excavating through various types of soil.
3. Economy With a variety of cutter disks available, the machine can be used for excavating through various functions will reduce the running cost to a minimum.
