PART 2 PRODUCTS

2.1 SYSTEM DESCRIPTION

2.1.1 Performance Requirements

Provide manufacturer’s standard safety devices as follows:

a. Provide pressure relief valve to avoid crushing obstruction encountered in either direction of travel.

b. Provide shut off power device if balance system fails.

Provide a manual bypass system which allows barrier to be opened and closed in event of power failure.

Design system to all for a minimum 2900 open and close operations per day.

Gate Height: Gate height shall match fence height as indicated on the drawings.

Gate Width: Gate width shall be as indicated on the drawings.

2.1.2 Additional Features

The following addition features shall be provided:

a. Cold Weather Package

b. Stanchion

c. Radio Controls – Provide standard open-close-stop commercial transmitters/receivers systems.

d. Provide detector system to allow free exit/safety, safety or close gate operation; system to be factory wired inside electrical box and tested.

e. Reversing Edge - Provide manufacturers standard reversing edge system.

f. Locks – Provide magnetic lock to secure gate in closed position

g. Photo Eye

h. Stainless steel fasteners

i. Heater for Electrical Box

j. Ice Scrappers

k. Weather Guard Package

2.2.3 Access Control Systems

The following access control shall be incorporated into the system:

a. Key switches

b. Pedestals

2.2 COMPONENTS

2.2.1 Hydraulic Power Unit

Hydraulic pump, motor, and reservoir will be all as one unit with fluid thermometer and fluid level sight gauge. The hydraulic system shall be designed to keep the gate locked in the closed position preventing a person from lifting the gate open when it’s in the closed position.

2.2.2 Hydraulic System

The hydraulic system shall consist of a 3000 psi hydraulic cylinder, limit switches and cushioned slow down on each end of travel, and adjustable stops with lock down in any position. Hydraulic fluid shall be the manufacturers standard fluid, factory checked, filled, and tested.

2.2.3 Balance System

Balance system shall be designed to allow barrier to be hand raised and to be hand lowered with 12 to 15 pounds of pressure. Provide built-in safety control switch capable of stopping barrier in any position should the balance system fails. Factory test and adjust the balance system to ensure gate may be manually raised and lowered with specified pressure. Signage to be added to the gate barrier must be declared at the time of order so the manufacturer can add the signs on the barrier to ensure the manufacturer can balance the operator correctly at the time of manufacturing.

2.2.4 Electrical System

Wire shall be oil and gas resistant. Provide Overload Protection relay to protect motor. Provide a Reversing Controller as required to operate motor and solenoid valves. Limit Switches shall be adjustable snap action style capable of stopping barrier at each end of travel. Provide a programmable logic board with manufacturer’s full range of available functions. All gates shall be equipped with a dry contactor to accommodate all types of access equipment.

2.2.5 Barrier System (Gates)

The gate system shall be designed to resist twist and sway.

Type: Manufacturer’s standard steel barrier (up to 20-foot-wide opening per gate leaf); minimum 9 gage galvanized chain link fence fabric, with sway bracing. Leading member of a steel barrier 4” schedule 20 round tube, sway braces- 1 ¼ x 1 ¼ x .087 square tube, uprights- 2 x 2 x .120 square tube. Sway braces bolted to barrier.

Type: Manufacturer’s standard aluminum barrier (up to 25-foot-wide opening per gate leaf), nominal 3.125” by 2.875” diamond 6063-T5 alloy aluminum screen fabric (amplimesh) welded both sides completely, with sway bracing.

Leading member of an aluminum barrier 4” schedule 40 round tube, sway braces- 1 ¼ x 1 ¼ x 1/8 square tube uprights- 2 x 2 x .188 square tube.

Sway braces bolted to barrier.

Type: Custom barrier as indicated on Drawings, with sway bracing.

Options: Provide stanchion to contain free end for severe crash applications; match barrier.

2.2.6 Accessories

Provide any additional accessories as required for a complete operational installation.

2.3 MATERIALS

2.3.1 Finishes

Finish shall be factory applied using a DTM epoxy prime coat and acrylic urethane topcoat.

2.3.2 Concrete

Provide concrete conforming to ASTM C94/C94M and obtaining a minimum 28-day compressive strength of 4,000 psi.

PART 3 EXECUTION

Submit manufacturer's erection/installation drawings and instructions that detail proper assembly and materials in the design for fence, gate, hardware and accessories.

3.1 PREPARATION

3.2 INSTALLATION

Installation shall be in accordance with manufacturer’s recommendations and installation instructions. Install vertical pivot gate system to provide rigid and secure installation as indicated, straight and true to lines and grades indicated, for free, easy operation. Install components square and level, accurately fitted and free from distortion and free from defects.

3.3 PROTECTION

Protect vertical pivot gate system form damage during all construction operations, replace components damaged by subsequent construction operations. Touch up minor scratched and/or damaged surfaces using the same primer and finish system applied by the manufacturer.

3.4 TRAINING

Provide training to owner personnel regarding programmable features and controls and preset controls according to Owner requirements. Provide training on proper operation, maintenance, and reprogramming of system.
