The Mid-Autumn Festival and National Day fall close together this year, and for most sites that means two things at once: a burst of traffic at the entrance, and then several quiet days when almost nobody is on site. An automatic bollard that runs all year rarely fails on an ordinary Tuesday. It tends to fail when the entrance is busy, or the day everyone comes back. Half an hour of checking before the holiday, and a shorter pass when you return, is the cheapest insurance you can buy for an entrance control system. Here is the checklist our own service teams work through.

Why the holiday is a turning point

Two states punish a neglected bollard. Before the break, vehicles queue and the columns cycle more than usual, which exposes weak terminals and tired batteries. During the break, the system sits almost untouched, often through autumn rain, with nobody watching, so water, grit, and corrosion do quiet damage. A check on both sides of the holiday keeps a small issue from turning into an emergency call-out.

Before the holiday: the thirty-minute walk-around

Start with the power. Open the control box and confirm the supply is stable, the breaker is not warm, and every terminal screw is tight. Loose terminals are the most common cause of intermittent faults we see, and they stay invisible until a column refuses to rise.

Check the backup battery. In a power failure the system relies on the small lead-acid battery in the control box to release the columns and keep the entrance usable. A battery that is two or three years old can still light the panel while lacking the capacity for a full cycle. If it is near the end of its life, replace it now rather than during the holiday.

Rehearse the emergency release. With the columns raised, confirm you can open the manual release and let them settle flush with the ground. This is the step that saves you when the grid goes down, and it is easier to practise while there is no pressure.

Test the remote control. Press every button and watch the response. Most remote faults are a flat handset battery or a receiver that has been shadowed by new metalwork. Range also drops in rain, fog, and wind, which is normal.

Clear the gaps. Grit, sand, and leaves collect in the narrow slot around each column. Sweep it out, and make sure nobody fills that gap with sand or debris, because it is exactly what stops a column travelling fully.

Check the drainage. In regions with heavy autumn rain, confirm the pit and the drainage route are clear so water cannot stand around the base. Standing water is the beginning of every rust and short-circuit story.

Finish with a full cycle. Raise and lower every column at least twice, listen for unusual noise, and stop immediately if a motor keeps running after the column has reached its limit.

While the site is quiet

You do not need to babysit the system, but two habits help. Avoid repeated up-and-down operation in a short time, because the motor heats quickly and there is nothing to gain from cycling the columns for fun. If the entrance is staffed, remind the guards to press stop if anything looks wrong, instead of letting a fault develop over the break.

After the holiday: a second, shorter pass

When the site fills up again, do a quick second pass. Clean the column surfaces and the control box, and dust off the electrical and mechanical areas. Lubricate the moving parts and the column as recommended, and re-tighten the mechanical fixings. If it rained heavily while you were away, look for any sign of water near the terminals.

Then return to the normal rhythm. Check the switches, buttons, and indicator lights once a month; check the terminal screws and electrical components once a month; and keep the surfaces free of dust. None of it takes long, and all of it is cheaper than an emergency repair.

When something is not right

If a column stops short, runs on, or makes a noise it did not make before, press stop and call a professional. Do not open the mechanism yourself, and do not keep operating it hoping it will settle. A ten-minute diagnosis now is cheaper than a burnt-out motor later. To confirm the right model or spare part before the holiday, our automatic bollards page lists the current range and control options.

A holiday is meant to be a break. Fifteen minutes at the control box before you leave, and another fifteen when you come back, is usually all it takes to keep an automatic bollard quiet and reliable through the busiest week of the autumn.
