600*219mm automatic bollards stainless steel bollard security retractable hydraulic rising bollard

Feature 1. Anti-collision：It can be used normally after being hit by a 12-ton vehicle. 2. Anti-destructive power：After being hit by a 16-ton vehicle, Hydraulic road bollards deformation. 3. internal structure：With load-bearing steel beam and column, anti-collision steel beam column, 4 navigation rods 4. Can be manually lowered in the event of a power outage 5. Linkage interface 6. Reversible operation according to requirements during ascent and descent 7. Noise during operation of the device≤60 dB 8. Waterproof integrated hydraulic drive 9. Control solenoid valve 24V 10. Control box display text adjustable (up, down, start, time control adjustment) 11. Display text in English 12. Water immersion performance：no leakage during 48 hours and normal lifting 13. Anti-corrosion performance level: 9 Detail 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. Drainage method: 1. Use artificial drainage or electric pumping mode, need to dig a small pool near the column, regular manual and electric drainage. 2. Use the natural drainage mode to connect directly to the sewer. A. At the installation junction (two), dig out two square grooves square grooves: (user-defined)mm (L)* 1000mm(W)* 1330mm(H) B. Fill the bottom of the groove with 200mm-high concrete, the precision requirement of the horizontal plane is high(Lifting column rack can be subjected to force), and at the middle of the side of the trough, leave a PVC# for drainage.
