The major feature of our products is very small thickness (from 10 to 27 cm). Due to this feature, all our blockers can be mounted right on the road surface. The construction of all the devices is unified, and in case of such mounting.
By this kind of mounting, all our devices perform two functions at once:
1. While “closed”, act as “sleeping policeman” (the device for forced speed lowing).
2. While “open”, entirely block the driveway. Transmission of all this equipment is hydraulic. Like bollards, one hydrostation can control several devices. It should be noted that in case of blocking devices, which corresponding to certain anti-ram classes, there is a need in the arrangement of «foundation» - reinforcement cages, onto which the device will be installed. Thus, underground concreted part becomes integral with the actuator and due to significantly increased area and weight provides proper protection class.
Nevertheless, this road blocking system still requires excavation works to be performed, but with full than devices requiring immersion of the executive part to a big depth. At the same time, it is important to remember that works to arrange reinforcement cages doesn’t requires special qualification and made of local materials (excluding the additional costs of transport) according to provided schemes, drawings, instructions and recommendations.
