B.Approved substitution – All other systems must be submitted to the design team in accordance with substitution requirements as set forth in the general provisions of the specification manual for approval prior to the bid date. Products submitted after the bid date will not be approved.

2.02Vehicle BARRIER:

A.The TCRB-360is a crash rated pivot arm certified to meet ASTM 2656-07 M50 crash rating. The complete TCRB-360 assembly consists of a receiver stanchion, hinge stanchion, aluminum arm, stanchion covers, and pumping unit. This unit was designed using the latest technology in parts and assembly including the use of engineered cables, stainless steel shafts, and details such as self-aligning bearings.

B.Mechanical Components:

  1. Buttresses (stanchions): The hinge and receiver buttresses are manufactured of steel components and welded steel elements.
  2. Hinge Buttress: The hinge buttress assembly includes internal bearings and stainless steel axle allowing the beam arc from 0 degrees up to 83 degrees (+/- 2 degrees) when in fully open position. A cushioning device is included to reduce beam oscillation. Covers are included to conceal operating system and prevent debris, ice or snow accumulation.
  3. Receiver Buttress: Receiver buttress is designed to guide the beam into place when lowered and retain the beam during vehicle impact. The receiver buttress includes a locking pin to prevent unauthorized operation of the unit when unattended.
  4. Beam: Beam is constructed of rectangular aluminum extrusion. The beam is finished in mill finish and reflective red and white safety tape to increase visibility. Reinforcement provided by a custom nylon cable installed in the beam and anchored with stainless steel rods
  5. Concrete: All concrete for installation is at or below grade. Above ground concrete/forming for buttresses/stanchions is not permitted allowing stanchion placement in close proximity to adjacent objects, walls etc.
  6. Hydraulic Cylinders: Clevis mounted within hinge side stanchion (buttress) and the beam arm. Clevis pins are designed to be easily removed and lubricated during normal maintenance.

C.Electrical and Hydraulic Components:

  1. Barrier Operation: The Power Unit is designed to operate from 220/230 single phase or 208/230/460V three phase 60 Hz; 50 Hertz is available.
  2. Power Unit: The Power Unit is housed in a separate cabinet and completely self-contained. Cabinet construction is of 14 gauge steel and is rated to NEMA 12. Outer cabinet contains all hydraulic components including a three gallon oil tank, up speed control valve, down speed control valve, manual release down valve, pump, manifold, connection hoses and fittings. Also included is an internal electrical cabinet to isolate and provide additional protection for the electrical components which include PLC (programmable logic controller), motor starter, motor overload, power disconnect, transformer, rectifier, and two loop detector bases. The electrical cabinet is rated to NEMA 3R. The Power Unit comes with one (1) pressure hydraulic hose at 15 feet in length and one (1) vent hose at 15 feet in length.
  3. Motor: The 1.5 HP motor is housed outside the electrical cabinet.
  4. A manual hand pump for operation in the event of a power failure is included standard.
  5. Hydraulic oil heater.
  6. Controls: TCRB-360 unit is provided with one set of “up” and “down” micro-switches supplied in the Power Unit cabinet for installation and testing purposes only. These testing controls are mounted in the control enclosure. TCRB-360 units require activation controls such as a card reader, keypad, push button, etc. (typically by others) for normal operation.
  7. Built in cycle counter to assist with maintenance scheduling.
  8. Built in auxiliary limit switches.
  9. Barrier lights.

D.Finishes:

  1. TCRB-360 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.
  2. The beam finished in mill Aluminum finish and striped with reflective red and white safety tape to increase visibility. ThePower Unit is painted industrial gray.
