PART II – PRODUCTS

2.1 CANTILEVER SLIDING CRASH GATE

A.	Application

1.	Cantilever gate shall be an above grade assembly consisting of a heavy steel structure capable of being opened and closed in a linear motion without the use of roadway track. When in the closed position it shall present an obstacle to an approaching vehicle. Upon impact, the force shall be first absorbed by the gate assembly and then transmitted to the end buttresses and foundations.

B.	Features

1.	Height of the barrier shall be 108 inches (2.74 M) as measured from the roadway surface to the top of the gate leaf.

2.	The standard clear opening shall be 144 inches (3.66 M) as measured inside buttress to receiver buttress supports. (The Barrier can be specified with a clear opening from 120 inches (3.66 M) to 360 inches (9.14 M)).

3.	The cantilever crash gate shall be positioned and locked in place by an electro-hydraulic rack and pinion drive mechanism.

4.	The Gate Leaf shall consist of a heavy steal I beam structure designed to withstand a vehicle impact of 15,000lbs at 50mph and carry a crash rating of K12 per D.O.S. Specification SD-SDT-0201.

5.	The hydraulic pumping unit will be designed to operate the gate with field adjustable speed controls.

6.	The receiver buttress will be constructed of two steel weldments, which are designed to direct the gate leaf to the hydraulic locking pin mechanism.  

7.	All serviceable parts will be easily accessible without the removal of the gate leaf.

8.	The buttress supports and sliding gate shall be coated Black with Sherman Williams Macropoxy 646 for superior corrosion protection. 

C.	Functional Specifications

1.	Unit shall consist of an electrically driven hydraulic pump which shall pressurize an accumulator.

2.	Power System

a.	The electric motor shall be capable of producing a minimum 3 horsepower.

b.	The unit shall be made available as 208/230 single-phase or 208/230/460 three-phase AC power. The motor shall be of the high starting torque, continuous duty, and industrial type, protected against overload by either a thermal or current sensing overload device.

3.	Control Circuitry

a.	A built-in PLC controller shall interface between the gate control stations and the hydraulic power unit. The PLC shall include all necessary inputs, outputs, timers and logic necessary for gate operation. Relays or proprietary control boards shall not be acceptable.

b.	The control circuit inputs shall operate from a 24 volts DC. An internal transformer and rectifier shall provide 24 volts DC for the control panel and customer dry contacts.

c.	There shall be 120 volts AC power available in the control cabinet for accessories requiring 120 volts.

d.	The control circuit shall be mounted in an enclosure with the hydraulic pumping unit. The enclosure shall be of sufficient size and rating to accommodate accessory devices.  All accessory device wiring shall connect to the included terminal strips.
