Description

The WG 4400 Road Tyre Shredder Blade is a heavy duty tyre disabling device, tested to 50,000kg load capacity and over 1 million cycles.

The operator can safely and remotely raise or lower the tyre shredding blades in a matter of seconds from a safe vantage point.

It is available in both permanent and portable options it can be integrated with other smart systems such as ANPR and access control devices.

It can be integrated with other systems and extended to cover large road sections, designed to prevent multiple or single vehicles entering or leaving a given boundary without authorisation.

A discrete permanent tyre shredding system designed for locations or fixed sites with high volume traffic flows or locations.

It is currently used at many different and varied facilities including major airports, oil & gas refineries, military bases, hotels and a range of other high value premises and is also used by the UK Border Force.

Standard Package

The system is supplied as standard with a fully in-cased powder coated steel electrical Control Panel that can be either wall or pole mounted.
The standard package contains 4 metres of Road Blade spike modules and the equivalent length of cast resin concrete trenches and steel in ground actuator casing that houses the actuator itself, as well as the necessary power and control cables. These are generally supplied to the customer’s requirement and additional charges may apply for extra long cable runs.
1 x 1.1KN torque electro mechanical actuator
1 x Actuator housing
1 x Electronic housing / Control Panel

1 x Back up battery pack (located in the above)
1 x Power connection cables*
1 x Control connection cables*
1 x Two push button activation control box
8 x 50.8 cm Road Blade modules
4 x Prefabricated Road Blade trenches
Cables are provided to suit individual system requirements additional cable costs may apply.

Optional Packages

System Lengths

The WG4400 is modular and can be extended in 1meter lengths up to a maximum of 8m of Road Blade spikes per actuator. Extending the system simply requires the installation of 2 additional Road Blade Spike modules and one trench per extra meter. A 4 meter standard Road Blade installation requires an area of approximately 5 meters in length to incorporate the in ground actuator housing and cables runs. Shorter non standard systems are also possible.

Thermostatic Heated System

To suit certain geographical environments the WG4400 can be provided with fitted heating elements to help prevent the build up of ice and snow on the Road Blade modules. This is recommended for areas where consistent or prolonged periods of snow and ice build up occur or with systems that are remotely situated and not able to be frequently maintained.

Remote Wireless Activation

For locations where the Road Blade may need to activated away from the activation control box or outside for instance the WGRB4400 can be supplied with remote wireless key fobs. This involves the factory installation of a transceiver to the Road Blade electrical package and the fitting of an external aerial to provide up to 200m of line of sight remote operation.

Lights and Barriers

Commonly many applications require additional features such as stop/go lighting or simple red warning lights that are actuated simultaneously with the Road Blade, likewise Siren alarms and rising arm barriers can also be provided in conjunction with the Road Blade package.

Covers

For situations where the Road Blade is likely to remain in-active for long periods of time, to prevent build up of debris in the trench beneath the Road Blade modules individual sacrificial rubber covers are available which can be fitted to the surface of each Road Blade spike module. However If the Road Blade is activated in a live scenario, the covers over the module in contact with the vehicle may have to be replaced afterwards.

Paint

The standard paint finish is powder coated matt or gloss black but other colours can be provided at the time of order.
