2. SPECIFICATIONS
APPLICATIONS
The CR-25 Electromechanical Crash Beam Barrier Gate will typically be used as a safety barrier. Typical applications will include embassies, nuclear facilities, "High-Risk" At- Grade crossings, government facilities where safety is an important consideration.
ENERGY ABSORPTION CAPACITY
The manual version of the CR-25 crash beam with 3/4" cable has been successfully crash tested per U.S. Navy specifications (OR-98-09-88 and M-56-86-05 with a level 1/L2 rating) and Department of the Army rating level of KN1-LN2. It is also listed by the U.S. Army Corps of Engineers in their document Protection Against Malevolent Use of Vehicles at Nuclear Power Plants (NUREG/CR-6190 Vol. 2, Rev. 1).
HOUSING
The housing will be fabricated from 3/8-inch steel plate and will be hot dip galvanized after fabrication. Formed, channel shaped side plates will be used to produce a strong configuration without welded corners. The housing will receive a finish coat of aluminum paint.
Access doors will be provided to service the operating mechanism and electrical equipment. The doors will be sealed with neoprene strip gaskets and bolted in place with corrosion-resistant, hex-head bolts.
The housing base will provide twelve 1-1/4 inch holes for mounting on the customer's foundation. Anchor bolts and template will be supplied by the gate manufacturer. Standard anchor bolts size will be 1.125-7 UNC X 2’-9” Long hot dip galvanized.
ARM
The beam arm will be constructed from 4-inch 6061-T6 aluminum pipe which will contain the wire rope assembly. Maximum arm length will be 25 feet.
Dimension "A", Shall be measured from the centerline of the pivot to the centerline of the bollard, will not exceed 322 inches. See Installation drawings for arm lengths.
Gate arms will be covered with 16-inch alternating red and white engineering grade reflective sheeting.
ARM MOUNTING TUBES
Arm mounting tubes will be hot dip galvanized carbon steel. The roadway arm shaft centerline will be 30-1/2 inches above the base line of the gate housing.
COUNTERWEIGHTS
Each gate will be equipped with suitable hot dip galvanized steel counterweights of the sectional, bolt-on type.
