Jacking Tops
Compact, robust design,
with jacking forces of up to
40Te per top.
These are simply bolted to
the base on the concrete
collar, and fed with supply
and return lines from one of
our Hydraulic Power Packs.
Jacking Bases
Sacrificial Jacking Bases are simply cast into
the initial concrete collar before shaft jacking
commences.
Jacking Tops are then bolted to the bases.
This removes the need for casting pockets and
HT bars used with some other systems.
Hydraulic Power

Hydraulic Power Packs.
Each power pack can be used
with up to 12 jacks; additional
