Can the barrier pole in the parking lot be lifted up?

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.

I observe this barrier pole every day when entering and exiting the parking lot. Actually, its internal mechanism is quite simple - just a motor driving a connecting rod. If the system fails, you can lift the pole by flipping the emergency switch at the base. However, ordinary car owners are advised not to tamper with it. Firstly, improper operation might scratch the vehicle body, and secondly, it could easily trigger the alarm system. Recently in our neighborhood, a car owner forcibly lifted the pole and was caught on camera attempting to evade payment. When encountering abnormal barrier pole behavior, it's recommended to directly contact the management office - they can remotely reboot the system within two minutes.

Manually lifting the barrier arm requires both skill and strength. The maintenance technician taught me the correct method: first locate the small wrench inside the hidden panel on the side of the pillar, turn it counterclockwise three times to release the motor lock, then use both hands to support the bottom of the arm and push upward. When lifted to 90 degrees, make sure to secure it with the positioning pin. To be honest, it's nearly impossible for us ordinary people to handle - the arm is as heavy as a barbell, and a single slip could smash the rear windshield. Nowadays, smart barrier arms come with self-diagnostic functions; if it really won't move, just ask security to handle it with the remote control.
