Hydraulic Road Blocker
Karen Systems Hydraulic Road Blockers are designed especially for entrance points which have a threat of vehicle attack or for the ones that have high security requirements. If there is a threat of vehicle attack in addition to the control of vehicle access in high security applications, hydraulic road blockers are the unique solution and the most secure systems. Even though the attack is from high tonnage vehicles with high speeds, it's not possible for the vehicle to keep on moving because of the damage given to front, wheels and the bottom of the vehicle.
Inflatable Dock Shelter
Karen HSYK-150 Inflatable dock shelters are used at the loading docks of warehouses and food manufacturing plants equipped with freezing rooms. Keeping strict control of temperature at the desired level is crucial. During loading/unloading operations a trailer partially backs into the dock shelter while the top and side airbags inflate around the truck body's top and sides providing tight sealing. When not in use the airbags deflated.
