Brosis Shield B12SM is a shallow Mount type hydraulically driven road blocker which requires maximum 400mm excavation depth for shallow Mount installation. SHIELD B12 SM uses clever linkage to open and close,not only does this provide much smoother, quieter operation than chain driven blockers. It also protects the potentially vulnerable hydraulic ram during impact.
Drainage system is provided so that accumulated dirt and water can be drained out and hence does not affect the mechanism of road blocker and its working efficiency.
