Hydraulic Swinging Mobile

Hydraulic Swinging
Flexibility:
Our hydraulic swinging hangar door
systems are available in many
configurations to meet your specific
requirements. Having built hydraulic
swinging door systems over 40' tall and
over 40 feet in width, with wind loads
(while closed) 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.

Hydraulic Door Operator:
Our hydraulic swinging doors utilize
hydraulic cylinders to control door frame
movement. By using hydraulic cylinders
to control door movement a large safety
factor is gained. Hydraulic fail safe
valves are used to lock the cylinder in
place if a control valve should fail or a
hydraulic line is ruptured or damaged.
The geomotry of the lifting cylinders is set
so that when the door becomes fully
open the hydraulic cylinders will be at the
end of their stroke. This allows the fluid
pressure to build and locks the cylinder in
position. When the door closes fully the
hydraulic cylinder becomes fully
compressed, allowing the fluid pressure
to build locking the cylinder in place.
Door closing speed is adjustable through
the factory installed speed control valve.
Simply adjust the valve until the door
closing speed meets your requirements.

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.

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
operating speed. Variable frequency
drives come with variable speed buttons
with 3 adjustable speed settings
standard, 5 speeds as an option.

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
(for ground mounted doors), explosion
proof drive system, electric safety eye,
12VDC backup hydraulic pump, engine
driven backup hydraulic pump. 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.
