Side Sliding Munitions Storage
Our side sliding blast door systems are available in many configurations to
meet your specific requirements. Having built side sliding blast doors to the
standard Type C,E and F magazines, "Stradley" and several custom designs
we are confident that we can fulfill you blast door requirements.
Doors are designed using CAD and structural engineering software. Door
frame structure and connection designs are certified by an independent
engineer (if spec drawings are not supplied or further design engineering
becomes necessary). Blast loads are calculated using U.S. Army Corp of
Engineers supplied software to insure the loads are correct and meet
Government requirements. Door frames are engineered using structural steel
and cold formed members per AISC and AISI codes. While usually insignificant
when compared to the blast loads, 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
verify every time.
Door components are manufactured to the highest standards and designed to
be bolt together where possible and allowed, avoiding costly delays due to
welding inspections and the availability of certified welders in the field. Doors
are fully assembled, welded and coated at our facility, ensuring a timely delivery
and installation to the job site.
Our support trolley wheels are machined in house on CNC lathes and
assembled using taper roller and needle roller bearings to transmit the vertical
forces imposed by the weight of the door and the lateral forces imposed by
wind, seismic and blast loads (when wheels are meant to restrain the door
instead of guide angle or catch). Support wheels are supplied with grease
fittings installed on the support axles. Support trolley is manufactured in house
to ensure the best designed trolley possible. Trolley is fully assembled and
wheel bearings are greased prior to shipment.
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. Drive motor is also equipped with a manual chain fall for
operating the door in the event of a power outage. Smaller doors are supplied
with the chain fall as standard with the option of adding a drive motor. Please
contact us for more information on the drive system supplied for your size/type
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.
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 drive
system mounted rotating limit that is connected to the door drive chain
sprocket. This design allows the overload clutch to slip without losing limit
switch timing. Interior door control buttons supplied are hazardous location
approved. 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.
Timer delay with safety noisemaker and/or strobe light, safety edge with delay
and/or auto reverse, personnel door frames and safety interlock sensors,
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.
