using Machine Mounts
using machine mounts, shown in figure 10, gives
the advantage of fast leveling and vibration reduc-
tion. the large size of the foot pads distributes
the weight of the machine to reduce strain on the
floor.
NOTICE
Anchor studs are stronger and more per-
manent alternatives to lag shield anchors;
however, they will stick out of the floor,
which may cause a tripping hazard if you
decide to move your machine.
anchoring the machine to the floor prevents it
from tipping or shifting and reduces any vibration
that may occur during operation, resulting in a
machine runs slightly quieter and feels more solid.
if the machine will be installed in a commercial or
workplace setting, or if it is permanently connect-
ed (hardwired) to the power supply, local codes
may require that it be anchored to the floor.
if not required by any local codes, fastening the
machine to the floor is an optional step. if you
choose not to do this with your machine, we rec-
ommend placing it on machine mounts, as these
provide an easy method for leveling and they have
vibration-absorbing pads.
Anchoring to floor
lag shield anchors with lag screws (see below)
are a popular way to anchor machinery to a con-
crete floor, because the anchors sit flush with the
floor surface, making it easy to unbolt and move
the machine later, if needed. however, anytime
local codes apply, you Must follow the anchoring
methodology specified by the code.
