Can the barrier pole in the parking lot be lifted up?
2 Answers
No, the relevant explanations are as follows: Reason: Generally, the barrier pole in the parking lot has a self-locking device. Either manually open the clutch and then lift the pole, or manually crank the motor. The barrier, also known as a vehicle blocker, is a specialized management device used at the entrances and exits of roads to restrict vehicle movement. It is now widely used at highway toll stations and parking lot systems to manage vehicle access, controlling the entry and exit of vehicles. Additional information: Electric barriers can be operated individually via wireless remote control to raise and lower the pole, or they can be managed automatically through a parking management system (i.e., an IC card management system). Vehicles are allowed entry by taking a card, and upon exit, they are automatically released after paying the parking fee.
The parking lot barrier arm can indeed be manually lifted, as I've seen maintenance personnel operate it several times. The base of the arm is designed with an emergency release mechanism, usually a hidden lever or knob, which can be unlocked with special tools during power outages or system failures. However, you should never attempt this yourself - those arms are extremely heavy, and improper lifting could damage your car roof. Last time a car owner forced it open and ended up breaking the motor gears, costing over a thousand yuan in repairs. Nowadays, most decent parking lots have backup power supplies. If the arm won't rise, the safest approach is to press the call button and wait for staff assistance.
