(K12) ATCRB-12 Crash Rated Articulating Barrier Arm & Hydraulic Operator System ASTM F2656 M50-P2/K12
Product Notes
- Closes single clear opening widths up to 40’.
Product Summary
The ATCRB-12 crash rated beam features an articulating drop arm, the ability to clear openings up to 40′, and is ASTM F2656-07 M50 P2 certified (equivalent to Department of State K12). The unusually large clear opening provided by this K12 crash beam boasts a breakthrough in vehicle crash testing. This combined with its ability to operate continuously or remain either deployed or retracted indefinitely regardless of local weather conditions presents perimeter security designers with an exciting new option for preventing vehicle intrusions. Finally, multiple drive lanes can be safely closed down with complete 15,000lb 50mph vehicle barrier protections without requiring huge adjacent recess area to store the barrier while not in operation.

Specification Features & Benefits
The TYM-ATCRB-12 is a crash-tested, hinged pivot arm system tested to meet ASTM 2656-012 M50 crash rating. The complete TYM-ATCRB-12 assembly consists of
- (1) pivot stanchion
- (1) receiver stanchion
- (1) aluminum arm
- (1) arm hinge
- (2) stanchion covers
- (1) hydraulic motor driven gearbox.
This unit was designed using the latest technology in parts and assembly including the use of engineered cables, high tensile, modified alloy shafts, and details such as self-aligning bearings.
The Drive Units are designed to operate from 230/240v single phase or 208/230 three-phase 60 Hz; 50 Hertz is available. The Power Unit is mounted directly to the stanchion completely self-contained. Cabinet construction is of 14 gauge steel and is rated to NEMA 3R. The outer cabinet contains all hydraulic components including a properly sized oil tank, up speed control valve, down speed control valve, manual release down valve, pump, manifold, connection hoses and fittings.
TYM-ATCRB-12 is delivered painted black (buttresses) with a three-part epoxy paint process: First mechanical and then chemical cleaning followed by a high- density zinc primer application and completed with 2-part epoxy paint for corrosion resistance. Other colors available, contact manufacturer for details. The beam shall be powder coated white and striped with reflective red and white safety tape to increase visibility. The Power Unit is painted industrial gray.
Frequently Asked Questions
TYMETAL has been in the perimeter security solutions market since 1985. With more than three decades of experience designing, manufacturing, and installing the (K12) ATCRB-12 Crash Rated Articulating Barrier Arm & Hydraulic Operator System ASTM F2656 M50-P2/K12, we have encountered many questions along the way. Explore a few of the common questions we are asked below. If you don’t find the answers you’re looking for, feel free to contact us by phone at 888-978-4283 or online.
How does DoS K12 compare against ASTM F2656 M50/P1 and what are the implications for penetration distance?
The U.S. DoS K12 designation is equivalent to ASTM F2656 M50/P1, requiring the barrier to stop a 15,000-lb vehicle at 50 mph within 1 meter of the barrier face. The P1 penetration class is the most restrictive, making the ATCRB-12 appropriate for standoff-critical installations where minimal intrusion beyond the barrier line is required after a vehicle strike.
How does this beam integrate with crash-rated gates and bollards for unified perimeters?
TYMETAL’s ATCRB-12 is designed to work within a comprehensive K12-rated perimeter system alongside TCG-12 cantilever slide gates, TCSG-12 swing gates, and K12 bollard products. The beam’s certified lane width and mounting system are engineered to align with adjacent rated barriers, ensuring the perimeter has no downgraded transition points between barrier types.
What is the mean time between service for hinges, pins, and hydraulic pivots?
Service intervals for the ATCRB-12’s articulating hinge system, pivot pins, and hydraulic actuator depend on operating cycle frequency and environmental conditions. TYMETAL provides model-specific maintenance schedules in the product installation documentation. High-cycle installations should follow the more frequent service intervals specified for continuous-duty applications.
What documented acceptance tests and commissioning checklists are required by owners?
TYMETAL provides commissioning documentation including functional test procedures, safety device verification checklists, and post-installation certification records. Owners and facility security managers should retain these records along with the original crash test certification documentation to support ongoing compliance audits and security accreditation requirements.
