Tiger Teeth
"Wrong-Way" Exits

Tiger Tooth Traffic controllers enforce "One Way" traffic flow for parking facilities or other single direction vehicle lanes. The torsion spring actuated Tiger Teeth positively control traffic in one direction while permitting free flow in the other direction. The Tiger Teeth will puncture all pneumatic tires including steel belted radial and large truck tires.

The TC28 incorporates Tiger Teeth that are rotated into position in less than 1.5 seconds by a highly reliable electro-mechanical system. The TC28 motorized traffic controller, with teeth sharp enough to cut paper, severely damages or deflates even the new generation of steel-belted tires.



General Notes:

TC28 traffic controllers are designed for standard vehicle traffic where the maximum axle load is less than 40,000 pounds and the tires are low pressure pneumatic.

IMPORTANT CONSIDERATIONS

1) The maximum vehicle crossing speed must be 5 MPH or less.

• Speeds above 5 MPH across the controller can result in tread or sidewall damage.
• Speed can be controlled by properly designed speed bumps, signs, stop/go signals, etc.

2) Traffic must cross the controller at 90 degrees.

• Crossing the controller at other than 90 degrees or turning directly over a controller can cause damage to the tread or sidewalls of vehicle tires.
• Proper selection and placement of the controller or the use of boundary posts, curbs, etc. can prevent turning or crossing at other than 90 degrees.

3) Traffic controllers should be located in a flat section of the roadway where there is minimal possibility that surface water will drain into the unit.

• Surface water draining into a controller can carry debris and trash that will potentially limit or restrict free actuation of the unit.
• Raising the controller slightly above the adjacent roadway can help this situation.

4) Pedestrians access to the area around the controller as well as the path of vehicles must be tightly limited.

• Proper site selection, cautionary signs, pedestrian banners, raised walls, etc. are some of the means of limiting pedestrian access to the area of a controller.

5) Where there is night-time vehicle or pedestrian traffic, or where visibility is limited, safety or auxiliary lighting should be provided.

6) After installation, a program of periodic inspection of the unit should be undertaken.

• Important in the proper continued operation includes checking and clearing debris that might have accumulated in the unit.
• Check to insure that water entering the unit is free to drain through the gravel bed.
• During the first 60 days of operation, weekly inspection should be conducted. Thereafter, monthly, or as needed.

Debris buildup within the body of the traffic controller can restrict the free movement of the teeth and result in tread or sidewall damage.

7) USR will be pleased to answer any general questions concerning the installation or maintenance of traffic controller, including technical recommendations concerning the design of foundations, roadways, placement of controllers, vehicle traffic routing, traffic pattern design, matters relating to pedestrian safety, lighting or other safety matters.
