Depending on the size and required
functions, sectional overhead doors
can be produced with manual
operation, reduction winch-assisted
manual operation, human controlled
motorized operation, or automatic
control motorized operation.
Manual operation is recommended
for small size doors, for which
remote operation is not necessary.
An indicative example is that of the
doors installed on logistic warehouse
openings, or applications with minor
maintenance requirements.
