Dia 219mm In Ground Bollard 1500 Cycles / Day 3s Raise Hydraulic Security Bollards

Hydraulic automatic bollard mainly consists of oil pump unit and steel frame construction. It use soil pressure as dynamic to realize the rise/fall of bollard.As a moving device, it is usually installed at vehicle entrance/exit. It rises to block the vehicle and falls the ground level to authorize free passing.

1. Automatically raise/lower/stop.The automated bollards adopt a heavy duty hydraulic power pack and operate by integrated control.Easy to install and operate. Built-in led flashing lights and reflective tap in the bollard head to ensure visibility and safety.
2. Variable frequency controller. Adopt variable frequency controller,the raise/lower speed 3-6s is adjustable.It can stop emergently during raising/lowering process. The control signal is electric transmission, quick and reliable.
3. Firm foundation plate.Thicken seamless 304 stainless steel with strong bearing capacity more than 40 tons. Rust protection and distortion resistance.
4. Built-in valve.In case of emergent issue for example power failure, the obstacle can be lowered by relief valve manually to make sure the passage of pedestrians and vehicles in not affected.
5. Adopt high quality great power motor, the bollards can raise/lower speedy,work stable and durable with 1500 cycles working frequency per day.The motor can be disassembled for easy maintenance.
6. Multiple security protection.Use high pressure air rifle to seal up the vent,the motor can work when soaked in water with electricity leakage protector.
