4.3.3 W orking with lug support
The lug support is mainly used for the lug profiles, with which the inside lug can be
supported or easily aligned.
First the required dimensions are set using the adjustment spindle. When setting the
dimension, the spindle play must be nullified, i.e. always move with the support
plates from the inside to the outside to the exact dimension! This thereby nullifies the
spindle play.
The cut profiles are placed onto the support plates and butted at the outer stops (in
case of pre-cut tolerances, the adjustment spindle must be readjusted to the dimen-
sion of the profile). For lug profiles, push the inside stop diagonally onto the inside
pipe corner and fix it with the Allen head screw.
If required, you can align the element corners (carefully) with the two horizontal
clamping devices.
The height of the lug can be adjusted with the lug support by adjusting the height us-
ing the threaded stud bolt.
Then tighten the vertical clamping element.
You can now start riveting and welding.
