K-Rated Vehicle Restraints in Minneapolis Gallery

What Minneapolis K-rated vehicle restraint options are available today?

Since the tragic events of September 11, 2001, the high security industry has continually grown, with more and more effective commercial security means coming down the pipeline. This is especially true of gates, fencing, cable restraint, fixed barriers, and access control. To get you started in the right direction, we’re listing just a few of the most popular installations utilized today.

Vehicle Barriers in Minneapolis

Vehicle barriers are categorized as one of two kinds: passive or active. Both can be movable or fixed, depending on how they are operated, used, or engineered. Some Minneapolis vehicle barriers are dual-classified — meaning they’ve been designed to meet the requirements for both passive and active barriers (e.g., portable passive, fixed-active, etc.) No industry-wide standard terminology exists for vehicle barriers, so the following definitions will be used:

Passive Barrier Systems

Passive barrier systems are classified as such due to a distinct lack of moving parts. The effectiveness of this barrier system depends on energy absorption and the transfer of the energy to its foundation. Examples of passive barrier systems include: ditches, bollards, highway medians, guardrails, posts, tired, and reinforced fences.

Active Barrier Systems

Active barriers require some form of action — by equipment, personnel, or both — to grant/deny entry. Moving parts are, thereby, required for this type of barrier system. Examples of active barrier systems include barricades, bollards, gates, beams, and active tire shredders.

Fixed Barrier Systems

Fixed barrier systems are permanently installed, requiring heavy equipment to be disassembled or transported. Fixed barrier systems can be either passive or active. Examples include pits, hydraulically-operated rotation or retracting systems, and barriers made of concrete or steel.

Portable Barrier Systems

Portable barrier systems can be passive or active and can be moved and relocated — though heavy equipment may still be required. Examples of portable barrier systems include: hydraulically operated, sled-type, barricade systems, highway medians, or filled 55-gallon drums not set in foundations.

Hydraulic Pop-Up Barriers

Hydraulic pop-up barriers are large, immovable barriers typically running the length of the drive, set at or below ground level, and designed to rise quickly in diverting fast-moving vehicular threats. Once given a signal to rise, hydraulic pistons quickly elevate the large steel road surface. These barriers can be easily installed on a temporary basis in less than 15 minutes.

Cable Restraint Systems

Cable restraint systems typically consist of ¾” to 1 ¼” diameter cables. They are installed at heights intended to stop and capture a vehicles. These systems may be either certified or uncertified. Certified cable restraint systems carry a K-Rating, which boils down to how far a vehicle of specific weight and size traveling at a specific speed will stop after running into the cables. The cables are strewn between posts in order to keep the vehicle restraint system at a certain height. At specified lengths, the cables are terminated with the use of a deadman system.

Hydraulic Bollards

Hydraulic crash bollards are ground-level steel bollards that rise up within a span of three seconds to stop fast-moving vehicular threats. Bollards are easy to operate: able to work in tandem with a simple three-button station or a sophisticated security system. Hydraulic bollards are used to protect United States embassies and federal facilities throughout the U.S. and abroad.

Crash Barrier Gates

Crash barrier gates help stop both foot traffic and fast-moving vehicular threats. These gates are popular in airport settings, helping prevent anyone or anything approaching grounded aircrafts. These gates require an electrical gate operator to move the gate at a speed of two feet per second to meet FAA requirements.

Barrier Arm Gates

Barrier arm gates raise and lower with a large tubular steel boom that has a cable assembly running through. Once in the closed position, the cable automatically loops over a large steel saddle horn. Barrier arm gates are designed to stop fast-moving vehicular threats. These gate arms are available for electrical/mechanical or manual operation.

High-Security Prison Gates

The requirements for prison fencing are many. Among the necessities are: extra vertical height, an absolute lack of gaps, and 100% foolproof. Operated from a remote site, a high-security prison gate—with its unique locking column and fully enclosed track and chain assemblies—cannot be overrun by hands-on intervention.

Gate Automation

Fingerprint scanners, retina scans, anti-passback, three strikes and tail gating, etc. Today’s gate automation devices are vast in number. Today, you can not only decide if people can access your perimeter but determine how often they can have access and at what time of the day — with the use of a personal PC and telephone entry device.

Concertina Wire

A severe form of “razor wire,” concertina wire can be found as a security application at nearly every American nuclear power plant and correctional facility. Available in a variety of diameters and types, this wire is also finding its way into the private sector as an impenetrable threat. Special consideration must be given to public safety prior to installation of concertina wire in Minneapolis.
