Automatic hydraulic bollards with a 219mm diameter are devices engineered to regulate vehicle entry and exit, often placed in sites such as roadways and parking areas.
Structural Features
The electrically operated bollards body is usually made of 304 or 316 stainless steel, featuring impact resistance and corrosion resistance.
Its wall thickness generally ranges from 6mm to 12mm and can be customized to meet different customer needs.
Working Principle
automatic hydraulic bollards operate based on hydraulic transmission technology and mainly consists of a hydraulic pump, hydraulic cylinder, control valve group, and sealing components.
When hydraulic oil enters the lower chamber of the hydraulic cylinder, it pushes the piston upward, driving the bollard to rise to the preset height.
During descent, the hydraulic oil flows back to the oil tank, and the bollard resets smoothly with the help of gravity or an accumulator.
Performance Parameters
Lifting speed: Typically 2 to 5 seconds.
Operating voltage: Usually 110V, 220V, or 380V.
Some products are equipped with a movement (core mechanism) with an IP68 waterproof rating, allowing them to adapt to extreme environments ranging from -30℃ to 75℃.
Typical Applications
It is suitable for locations that require vehicle access control, including government buildings, airports, shopping malls, hospitals, schools, and parking lots. It can prevent vehicles from forcing entry and ensure safety and order within the area.
