Sigma Portable Spike Strip – Controlled Vehicle Stopping and Tire Deflation System

The Sigma Portable Spike Strip is a professional, portable, and reusable tire deflation and vehicle stopping system developed for use at checkpoints operated by law enforcement agencies, police forces, gendarmerie units, military organizations, and authorized security personnel.

The system is designed to interact with the tires of appropriate vehicle classes through specially engineered stainless-steel spikes when a vehicle fails to comply with a stop order, attempts to evade a checkpoint, or makes an unauthorized passage. This interaction helps reduce tire pressure in a controlled manner.

The primary purpose of the Sigma Portable Spike Strip is to support the gradual reduction of a vehicle's mobility rather than causing an immediate and uncontrolled loss of tire pressure.

Thanks to its portable and foldable design, the Sigma Portable Spike Strip can be easily transported and prepared for use at temporary checkpoints where permanent vehicle barrier infrastructure is unavailable. Different length options allow the system to accommodate various road widths and operational requirements.

Controlled Tire Pressure Reduction System

At the core of the Sigma Portable Spike Strip is a specially developed stainless-steel spike system.

When a vehicle tire comes into contact with the system, the spikes may penetrate the tire. Their hollow construction allows air inside the tire to escape in a controlled manner.

The objective is to gradually reduce the mobility of the target vehicle and support the ability of authorized security personnel to manage the intervention.

The behavior and stopping distance of a vehicle after contact with the system depend on several variables, including:

• Vehicle speed,

• Vehicle weight,

• Tire type and construction,

• Road surface,

• Weather conditions,

• Driver response,

• Degree of contact between the tires and the system.

For this reason, a fixed or guaranteed stopping distance should not be assumed for any vehicle.

Portable and Foldable Body Design

One of the key advantages of the Sigma Portable Spike Strip is its compact and foldable body design.

After use, the system can be folded inward from both ends toward the center, reducing its overall size for transportation and storage.

Once the deployment/retrieval rope has been properly wound onto the reel, the main unit, spare parts, and other accessories can be placed in the dedicated carrying case.

This design allows the Sigma Portable Spike Strip to:

• Be easily transported in operational vehicles,

• Be transferred between different checkpoints,

• Be stored in areas with limited storage space,

• Be deployed to different locations during mobile security operations.

Unlike permanently installed vehicle barriers, the system does not require permanent infrastructure, providing an important operational advantage in mobile and temporary security applications.

Operating Principles of the Sigma Portable Spike Strip

The Sigma Portable Spike Strip must only be used by personnel who have received the necessary training and have been authorized by the relevant organization.

Before deployment:

• The target vehicle should be positively identified,

• The vehicle class should be assessed,

• Road and traffic conditions should be evaluated,

• A safe position for operating personnel should be established,

• Communication with pursuit and support units should be maintained,

• Non-target vehicles and other road users should be taken into consideration.

The deployment/retrieval rope and supporting equipment must only be used in accordance with the manufacturer's instructions and the operational procedures of the relevant organization.

The system should not be deployed if the target vehicle cannot be reliably identified, communication is lost, or adequate safety for personnel and surrounding road users cannot be maintained.

The different length options allow the appropriate model to be selected according to the physical characteristics of the road and the operational requirements of the organization.

Replaceable Spike and Spare Parts System

The Sigma Portable Spike Strip features a modular structure designed for maintenance and repeated use.

During an operation, some spikes may remain embedded in vehicle tires or separate from the main body. Missing spikes can be replaced with compatible spare parts designed for the relevant Sigma Portable Spike Strip model.

During maintenance, the following components should be inspected:

• Stainless-steel spikes,

• Lower seals,

• Upper protective caps,

• Body modules,

• Connection components,

• Deployment/retrieval rope,

• Winding reel.

Missing or damaged components should be replaced with suitable compatible parts.

The system should only be considered ready for operational use after all necessary maintenance and safety inspections have been successfully completed.

Sigma Portable Spike Strip Inspection and Maintenance

Before each operation, the Sigma Portable Spike Strip should be fully opened and subjected to a general inspection.

Particular attention should be given to:

• Loose spikes,

• Missing or damaged spikes,

• Cracks or deformation in the body,

• Hinges and modular connection points,

• Lower and upper seals,

• Condition of the deployment/retrieval rope,

• Functionality of the winding reel,

• Carrying case and spare parts.

Any missing or damaged components should be replaced with compatible spare parts before the system is used.

Modular Repair Advantage

The modular design of the Sigma Portable Spike Strip allows individual sections of the body to be assessed separately if damage occurs.

If a damaged module is replaced or the system configuration is modified, the equipment must be inspected by authorized personnel before being returned to operational service.

The inspection should include:

• Connection integrity,

• Mechanical safety,

• Current system length,

• Suitability for the intended road width,

• Compliance with the organization's operational procedures.

Removing one or more modules and shortening the system does not automatically mean that the resulting configuration is suitable for operational use.

Cleaning and Storage

After an operation, foreign materials accumulated on the Sigma Portable Spike Strip should be removed, including:

• Stones,

• Soil,

• Mud,

• Grass,

• Dust,

• Other debris.

Petroleum-based cleaning products or chemicals that have not been approved by the manufacturer should not be used on plastic or rubber components.

After cleaning, the system should be completely dried and carefully folded.

Spare spikes, the spike installation tool, deployment/retrieval rope, winding reel, and other accessories should be placed neatly in their designated compartments inside the carrying case.

The equipment should be stored in a clean, dry, and secure environment that is inaccessible to unauthorized persons.

Periodic Inspection

Sigma Portable Spike Strip systems that are not actively used should also be inspected periodically.

Unless a different maintenance interval is specified in the manufacturer's technical documentation or the organization's procedures, a system that has remained unused for an extended period should be fully opened and subjected to a general inspection at least once a year.

Intensive operational use, high humidity, extreme temperatures, dust, mud, and other demanding environmental conditions may require more frequent inspection and maintenance.

Applications of the Sigma Portable Spike Strip

Thanks to its portable design, the Sigma Portable Spike Strip can be used in a variety of authorized security applications, including:

• Police and law enforcement checkpoints,

• Gendarmerie road control operations,

• Military facilities and controlled entrances,

• Border crossings,

• Customs areas,

• Critical public facilities,

• Temporary security checkpoints,

• Controlled vehicle entry and exit points,

• Authorized professional security operations.

Where permanent vehicle barrier infrastructure is unavailable or a mobile security solution is required, the system can be deployed as a portable vehicle stopping and tire deflation system.
