The latest model of HVM Terra Blocker with Shallow Mount Technology, successfully impact tested to the new International IWA 14 specification stopping a 7.2t vehicle travelling at 80kph (50mph).

The test resulted in the vehicle being stopped with zero penetration. The Blocker remained fully functional after impact illustrating the outstanding protection the blocker can provide from the threat of VBIED’s (vehicle borne improvised explosive devices).

As a foundation type B, with an embedment depth of only 300mm required, the Shallow HVM Blocker offers protection to sites where minimal foundation depths are available.

The footprint and weight has been reduced by approximately 60% from its predecessor. The new shock absorber dampening springs are designed to absorb and damp shock impulses. This specialist system designed by Frontier Pitts converts the kinetic energy of the shock into other forms of energy which are then dissipated.

Simulated to stop 12t@ 80kph, the high carbon struts work on 3 axis and may allow the MKII blocker to be pre tested for energy absorption prior to delivery.

Hydraulically driven. Designed for ease of installation and maintenance. The Blocker can be interfaced to any access control systems. Traffic Light System included as standard.

The Terra Shallow Blockers top plate can be finished with Frontier Pitts Lifetime Paint; an anti skid resistant treatment which has been fully tested under laboratory conditions for at least 12 months.
