The Road Spike Tire Spike System By PMG

Click here to read about the history of the Road Spike. The Road Spike was designed with officer safety first and foremost. It is the only system in the world which removes the officer from the direct line of traffic and can be pre-deployed. Since the Road Spike tire spike, or spike strip,will not puncture tires until activated, it can be pre-deployed any time before the target vehicle is in sight. Other vehicles can travel over the Road Spike with no damage to their tires.

The officer can be safely removed 30 feet from the side of the road and stand behind his or her vehicle or another protective barrier. When the target vehicle is in sight, the officer activates the spike with a simple hand level. The spike will come out of their protective pads and embed themselves into the tires of the target vehicle.

The tire spikes are hollow which deflates all tires, even run flat tires, but with a controlled rate of deflation so not to cause the target vehicle to become unstable and endanger nearby officers or other vehicles who happen to be on the road at the same time.

The officer then de-activates the tire spikes and the spikes retract back into their protective pads. This allows for the Road Spike, spike strip to remain on the road while the officer apprehends the people in the target car. Once the person or persons are in the control of the police officer, then the office can go back and retieve the Road Spike at any time that it is safe for him or her to do so.

The pre-deployment and removal of the officer from the side of the road eliminates the risk to other vehicles, but most importantly to the officer deploying the Road Spike. Gone are the days of having to stand on the side of the road with a potentially dangerious person behind the wheel of a car driving 80, 90, 120 mph head first at you, and you having to stand there trying to time throwing a spike strip in front of that car, trying to yank it back and hope you don't get hurt, or hope that another vehicle doesn't get involved.

Road Blade Tire Shredding System by PMG

tire shredder and tire spike for two way road control

The Road Blade by PMG is a versatile multi-directional, on demand tire spike or tire shredding system. The Road Blade is an aggressive tire killer designed to bring a vehicle to its rims immediately. This does a great job in protecting high worth areas such as embassies, military bases, parking lots. The road blade is multi-directional and on demand, meaning that unlike one way tire spikes, the Road Blade can be activated when needed, and when activated, the road is shut down from either direction. The Road Blade has been used at intermodals and auto auction sites to stop theft of vehicles and property where thieves were either driving the wrong way, or laying down  covers over spring loaded one way tire spikes.

By bringing a car to its rims immediately, the Road Blade provides vital reaction time to base security personnel, when they need to determine intent. The Road Blade provides final denial for controlled perimeters per the Unified Facilities Criteria

The Road Blade can be installed in any of three different configurations; flush with the road surface, laying on top of the road, or portable. With the flush mounted units there is an option of installing covers which lay on top of the system when the blade are down to help protect the system from debris or build up. For those in areas of the country where snow is expected, an optional heating element can be installed to melt the snow around the Road Blade for year round service.

The surface mounted Road Blade Tire Shredding system can be affixed directly to the road. It can be laid on top of asphalt, concrete or even dirt roads. It will stay secure and will not move. This configuration allows for semi-permanent installs. This is a perfect compliment to military gate and road control. It is also very effective for any application where the goal is to control road access with the lowest possible budget.

When the blades at retracted, they are recessed in the modules and the system serves as a mini speed bump. Both the flush mounted and surface mounted systems can be operated manually or integrated with arms, lights, access key pads and other accessories.

The Road Blade Tire Shredding System can also be used as a portable road access control measure. The individual modules can be stacked and transported to the site when needed. Each module will interlock with the next module and either operated with a manual arm, or integrated with gates, arms and lights. This is what DESRON 22, the US Naval squadron which includes the U.S.S. Cole does when they go from port of call to port of call.

One Way Tire Spike Treadle Systems By PMG

surface mounted directional close up

One way tire spike systems are an economical method for controlling traffic in and out of lots. These systems are manufactured in the United States by PMG and can now be used with arms, gates, key pads and other accessories. These are the spring loaded one way systems most are familiar with at car rental lots.

Our systems are contrusted from high grade 3/8" steel plates and include replaceable teeth and springs. These system can be made in varying lengths to meet the specific lane profile.

Just as with the Road Blade Tire Spike Systems, the Directional One Way Tire Spikes can either be flush or surface mounted.

Our flush mounted One Way Tire Spike system has uniquely designed teeth. These teeth were specifically designed by PMG to allow cars traveling in the correct direction to roll over the teeth and the teeth not to 'clip" the tire. Most systems have a straight blade, the problem with this is that certain car's tires will touch the top of those blades, causing the blade to 'clip' the tire and take a small piece out of the tire. Many people have had to replace tires because of this design flaw found in most other's tire spikes.

The systems designed by PMG today solve this problem, while also being aggressive to deflate tires on any vehicles coming the opposite direction.

The one way directional, or sometimes known as treadle systems, tire spikes system can be used with manual or automatic arms, gates, key pads, barriers, heating elements and other accessories. The modular design allows great flexibility to protect your unique access points.

The removable cover plates allow for easy maintenance for the changing of springs or teeth as needed. The heavy duty plates, and special teeth provides the highest quality product available.
