The environment
is precious
and each of
us must do
our part to
protect it.
At SIGMA,
protecting
the environment
from in-ground
leaking of
hydraulic
cylinder is
vital.
There are
many ways
to keep hydraulic
oil contained
in an in-ground
cylinder but
the best way
is not to
have the cylinder
in the ground
at all. To
this end,
SIGMA
has
adopted holeless
elevator systems.

Our products including ropes
