Side Sliding
Flexibility:
Our side sliding hangar door systems
are available in many configurations to
meet your specific requirements. Having
built side sliding door systems over 80'
tall, hundreds of 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:
Doors are designed using CAD and
structural engineering sotware. Door
frame structure and connection designs
are certified by an independant engineer.
Door frames 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:
Door 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.
