Tring
Corporation has experience building ladder swaging
presses for aluminum and fiberglass ladders. Some of
these systems can also swag rungs into stages and
planks. We have built systems for both round and "D"
shaped rungs. These machines can process various length
of rungs with simple width adjustments.
This process requires that the
aluminum rungs be annealed. It is a two step operation,
first the rung is upset. Then the rung is installed into
the rail and the outside upset is applied. Machines can
be built to attach rungs to attachment plate as will as
directly to rails.
