Commercial
sites have needs that are very different
from residential applications, frequency of
use being the most common difference.
Whereas the typical garage door opener may
only be used a few times daily, a commercial
operator may be used several times an hour.
With this heavy industrial usage in mind,
LiftMaster®
has developed a full line of operators that
provide the highest levels of strength and
durability. LiftMaster professionals can
assess precisely what you need and install a
reliable system your business can count on
for many years to come.
Typically
used for standard lift sectional doors,
trolley operators are available in light,
medium and industrial-duty. The applications
for trolley operators range from residential
or light-duty applications to heavy-duty
industrial applications.
This line of operators also includes a low
profile, apartment house operator.
Jackshaft
operators are designed for use on rolling
grilles and shutters as well as rolling
doors. Some operators are also designed for
use on industrial sectional doors with high
or vertical lift.
Jackshaft operators are available in light,
medium, industrial and heavy
industrial-duty.
Hoist
operators are designed for use on rolling
doors and grilles as well as industrial
sectional doors with high or vertical lift.
Hoist operators are available in medium,
industrial and heavy industrial-duty.
Slide door operators are designed for use
on single and bi-parting slide doors and
fire doors.
They are available in industrial and
heavy-industrial duty.
The
LiftMaster High Cycle Trolley Operator meets
the challenge of today´s heavy-duty
applications by providing the ultimate in
durability, quiet operation and security.
LiftMaster®
release devices control the closure of a
rolling fire door, counter fire door, fire
shutter or track door in an emergency
situation. Release devices work in
conjunction with the door or shutter to
provide an effective fire and smoke control
system by preventing spread beyond the area
of origin. The device's basic function is to
provide a time-delayed release of fire door
or shutter upon receiving a signal from a
smoke detector or central alarm station (or
other remote switching device) or upon loss
of power. Release devices are also an
integral part of the fusible link assembly,
releasing the door or shutter when the
fusible link separates.
Models are available for use with both
non-motorized and motorized door
applications. For motorized door
applications, select models can be used to
create a fully automated door closing system
when used in conjunction with a standard
commercial operator by providing features
typically found on expensive, special-order
fire door operators.
