crash beam, bearing assembly, hinge end support column locking end support column with
provisions for a locking pin with padlock provision, mounting hardware, with other options as
defined herein.
1.1
U.S. PATENT LICENSE. The CRASH CERTIFIED DROP ARM BEAM BARRIER
SYSTEM shall be fully licensed for manufacture under U.S. Patent Number 4,844,653
dated July 4, 1989.
2.0
SYSTEM CONFIGURATION
2.1
Barrier Construction. Barrier shall be an above grade assembly containing a crash beam
hinged at one end, which can be rotated manually. When in the closed position the beam
shall present a formidable obstacle to approaching vehicles.
2.2

from the roadway surface to the centerline of the crash beam. Height can be varied during
installation to suit local security requirements.
2.3
Barrier Clear Opening. The standard clear opening shall be 144 inches (3,66 M) as
measured inside to inside of the buttress supports. The Barrier can be specified with a
clear opening up to 360 inches [9,14 M].*
2.4
Finish. The foundation base of the Barrier shall be asphalt emulsion coated for corrosion
protection. Exposed barrier surfaces shall be painted with a gloss white, two-part epoxy
high weather resistant paint (or optional galvanized finish). The drop arm beam shall be
finished with reflective tape (red and white diagonal stripes) across the front and back
faces of the crash beam.

with a locking pin with padlock locking point to secure the Barrier in the guard position.
Padlock (7/16 inch [11mm] or smaller shackle) to be furnished by others. (Note: When not
attended, locking pins provide resistance to opening of the barrier by unauthorized
personnel. The Crash Rating of the Barrier System (3.1.2) is without locking pins).
6.0
QUALITY ASSURANCE PROVISIONS Testing. Upon completion, the Barrier system will
be fully tested in the manufacturer's shop. The following checks shall be made:
6.1
Identification. A nameplate with manufacturer's name, model number, serial number and
year built shall be located at the hinged end structure.
6.2
Workmanship. The Barrier shall have a neat and workmanlike appearance.

DISCLAIMER
8.1
Please note - careful consideration must be devoted to the selection, placement and
design of a Drop Arm Barrier System installation. Just as in the case of any Barricade
system, perimeter security device or security gate those blocks a roadway or drive, care
must be taken to ensure that approaching vehicle as well as pedestrians are fully aware of
the Barriers and their operation. Proper illumination, clearly worded warning signs,
auxiliary devices such as semaphore gates, stop-go signal lights, audible warning devices,
speed bumps, flashing lights, beacons, etc. should be considered. Delta has information
available on many such auxiliary safety equipment not specifically listed herein. It is
strongly recommended that an architect and or a traffic and or safety engineer be
consulted prior to installation of a Barricade system. Delta will offer all possible assistance
in designing the operating equipment, controls and the overall system but we are not
qualified nor do we purport to offer either traffic or safety engineering information.
