BZ70 Hydraulic walking pile frame is our heavy
equipment which is integrated by mechanical,
electrical and hydraulic systems. It is specially
made for SMW(Soil Mixing Wall) construction.
As a 70 tons grade pile frame, this type machine
integrated by new hydraulic system is developed
from our JB series Hydraulic walking pile
frame technology and construction experience
through improved quality and performance. This
equipment not only can be hung with SMW multishafts
drilling machines, but also can be used in
other foundation construction projects. So this high
performance model machine is a multi-functional
equipment to work in foundation projects, such as
bridges, harbors and diaphragm walls.
