Freestanding Side Slding Mobile

Freestanding - Side
Sliding
Flexibility:
Our freestanding side sliding hangar
door systems are available in many
configurations to meet your specific
requirements. Having built freestanding
side sliding door systems over 65' tall
and 230 feet in width, with wind speeds
up to 200mph, we are confident that we
can build a system that will meet your
requirements or your imagination.

Design:
Freestanding support frame and door
frames are designed using CAD and
structural engineering sotware.
Freestanding support frame and door
frames structure and connection designs
are certified by an independant
engineer. Structures are engineered
using structural steel and cold formed
memebrs per AISC and AISI codes.
Wind loads are calculated using your
location and building size for the most
accurate structural loading possible. We
don't make an assumption on the wind
load by using an arbitrary standard, we
check every time.

Construction:
Freestanding support frame and door
frames components are manufactured to
the highest standards and designed to
be completely bolt together, avoiding
costly delays due to welding inspections
and the availability of certified welders in
the field. Door components are also
designed to have as few connections as
possible, simplifying and increasing
assembly speed on the job. This lowers
the total installed cost for your door
system.

Support Wheels:
Our support guide wheels are machined
in house on CNC lathes and assembled
using taper roller bearings to transmit
the vertical forces imposed by the weight
of the door and the lateral forces
imposed by wind and seismic loads.
Support wheels are supplied with
grease fittings installed on the support
axles and taper bearing adjusters.
Support wheels can be removed from
the door panel through the top of the
wheel box, allowing bearing/axle
maintenance without having to remove
the door from the track.

Top Guide Wheels:
Door top guide wheels are equipped
with permanently lubricated roller
bearings to ensure long life and low
maintenance requirements. Door top
guide wheels are mounted on a
telescoping guide bracket that will
expand and collapse to absorb
differences in guide rail height due to
live and seismic forces exerted against
the building. Top guide bracket can be
made to absorb virtually any building

Drive System:
Drive motor(s) is installed onto a
mounting plate that is adjustable for
chain tension. Drive motor has a worm
gear drive gearbox and is equipped with
a motor brake that is directly mounted to
the drive motor for the Chain drive
features an overload clutch to prevent
damage in the case of overloading.
Overload clutch is easily released,
allowing manual operation in the event of
a power failure.

Weatherstrip:
Weatherstrip is 1/8" cloth inserted
epdm. Weatherstrip meets military
specifications for durometer, UV
resistance and incidental exposure to
paint thinners. Retainer bar is fastened
by zinc coated self drilling screws every
8" for a secure seal without oil canning
of retainer bar. Retainer bar is easily
removed for replacement of
weatherstripping if it becomes
necessary. Leading edge bubble seals
alow for 4" of compression.

Electrical Controls:
Door control panels are manufactured in
house using only the highest quality UL
listed components. Door control systems
utilize electromechanical relays that are
highly resistant to electrical interference
and have no programming that can
become corrupted requiring service.
Door control systems also utilize solid
state proximity sensors for limiting door
travel. These sensors are water proof
and have no moving parts to wear out.
Door control systems can be supplied
ranging from 12VDC to 600VAC.
Variable frequency drives are available
for custom tuning or varying of door drive
speed. Variable frequency drives come
with variable speed buttons with 3
adjustable speed settings standard, 5
speeds as an option.

Power Feed:
Standard power feed system supplied
is a drape cord design. With no trolleys
to wear out or become tangled a drape
cord system offers many years of trouble
free service. Also available is a trolley
duct power feed system. Trolley duct
power feed offers a superior installed
appearance and very long service life.
Trolley duct can be ordered in straight
and radiused sections so virtually any
type of door system can be designed for
trolley duct.

Standard Options:
Timer delay with safety noisemaker
and/or strobe light, safety edge with
delay and/or auto reverse, personnel
door frames and safety interlock
sensors, bumper door collection system,
cable drive door collection system,
explosion proof drive system, air drive
operating system, hydraulic drive
operating system. Door drive motors
and control panels are fully assembled,
wired and tested at our facility prior to
shipping.

Please call with your custom option
requirements, we are here to create the
system that meets your needs and your
imagination.
