Semi-Automatic Bollards

Bollard Structure:The bollard consists of three parts: a tin casing, sleeve and bollard. The protruding bollard allows passage of 5-ton wheels. The post and the piston, including the piston casing, can be removed from the casing, which enables treatment of the gas piston. The cover screws are made of stainless steel. The sides of the posts base move through tracks that are part of the casing. The bollard sleeve fits exactly into the casing. The casing includes a fluid drain. The casing connects to the concrete and is galvanized and hardened to prevent warping during casting. Gas Piston:The bollard is designed around a compressed gas piston system. The top of the foundation protrudes approximately 30 mm above ground to reduce the amount of water entering the bollard base. The bollard is 6 or 8 in diameter. Installation:The bollard sleeves with the tin outer casings are incorporated into the mold of the concrete, while maintaining strict leveling and proper connection to the concrete and the reinforcement. The top of the bollard and the cover are level with the concrete.The top of the bollard base is raised 30 mm above the level of the road in the area in which the bollard is located. Digging for the concrete foundation is carried out in coordination with the construction of the road. The bollards rise and lower perpendicular to the ground. Each group of bollards forms a straight line. Bollard Activation:To lower, turn the key and step on the bollard.The bollard lowers and locks automatically.To raise, simply turn the key and the bollard rises automatically.The bollards serve as security barriers that prevent intrusion of vehicles at high speeds.
