(K4) ATCRB-4 Crash Rated Articulating Barrier Arm & Hydraulic Operator System ASTM F2656 M30-P2/K4
Product Notes
- Closes single clear opening widths up to 40’.
Product Summary
The ATCRB-4 crash rated beam features an articulating drop arm, the ability to clear openings up to 40′, and is ASTM F2656-07 M30 P2 certified (equivalent to Department of State K4). The unusually large clear opening provided by this K4 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 30mph 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 M30 crash rating. The complete TYM-ATCRB-4 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-4 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 (K4) ATCRB-4 Crash Rated Articulating Barrier Arm & Hydraulic Operator System ASTM F2656 M30-P2/K4, 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.
What articulation geometry enables clearance in low-headroom sites?
The ATCRB-4 articulating barrier arm is designed to fold or pivot during deployment, allowing it to clear overhead obstructions that would prevent a straight-rise barrier arm from operating. This makes it suitable for covered parking structures, underpasses, and building-integrated access points where standard upright barrier arms would conflict with ceiling or canopy height restrictions.
What hydraulic pressure set-points and sensors prevent over-travel?
TYMETAL’s ATCRB-4 hydraulic system incorporates pressure relief valves and limit switches that prevent the arm from exceeding its designed range of travel. These components protect the structural arm, hinge system, and operator from damage due to over-extension or obstruction, ensuring consistent operation within the parameters validated by the ASTM F2656 M30/P2 crash certification.
What compatible safety devices are required for P2 installations?
P2 installations of the ATCRB-4 should include vehicle detection loops, photo eyes, and edge sensors as required under UL 325 for automated vehicular barriers, ensuring the system does not lower the barrier arm onto a vehicle occupying the lane. Emergency stop controls and access control interfaces should be specified per the site’s security design and safety compliance requirements.
