Electric Roller Shutter Power Supply Requirements

A powered door often reaches site before anyone has confirmed what will feed it. The installer then asks a question that belongs at order time: does this motor run on the building’s single-phase supply, or does it need a three-phase feed? Asked late, the answer costs a breaker swap, a new cable route, or an ... <a title="Electric Roller Shutter Power Supply Requirements" class="read-more" href="https://www.raxdoors.com/blog/electric-roller-shutter-power-supply-requirements/" aria-label="Read more about Electric Roller Shutter Power Supply Requirements">Read more</a>

Electric Roller Shutter Accessories You Actually Need

Every supplier page lists the same parts for an electric roller shutter: a motor, a remote, some guides, a few seals. What the lists rarely explain is which parts have to be chosen together. A remote that shares the frequency but not the coding pairs with nothing. A motor sized without the curtain weight runs ... <a title="Electric Roller Shutter Accessories You Actually Need" class="read-more" href="https://www.raxdoors.com/blog/electric-roller-shutter-accessories/" aria-label="Read more about Electric Roller Shutter Accessories You Actually Need">Read more</a>

Why Motorized Security Shutters Need a Manual Override

The power fails on the late shift and the shutter freezes half open. Outside, the yard keeps moving; inside, a steel curtain hangs in its guides and the control panel is dead. Nobody on the floor knows that the box hides a drive socket, where the crank is stored, or that the brake they are ... <a title="Why Motorized Security Shutters Need a Manual Override" class="read-more" href="https://www.raxdoors.com/blog/manual-override-security-shutters-guide/" aria-label="Read more about Why Motorized Security Shutters Need a Manual Override">Read more</a>

Industrial Door Locks: Types, Grades and Fit

A roller shutter at the back of a warehouse was attacked overnight. The curtain panel has already been replaced, and the paint is fresh. The only trace of the incident is a punched hole at the bottom rail where a bullet lock used to sit. Nobody ordered a new lock with the panel, so the ... <a title="Industrial Door Locks: Types, Grades and Fit" class="read-more" href="https://www.raxdoors.com/blog/industrial-door-handles-lock-guide/" aria-label="Read more about Industrial Door Locks: Types, Grades and Fit">Read more</a>

Industrial Door Counterweight Systems: How They Balance

The leaf in the overhaul bay needed two people to move it, and the maintenance log said only that it had “got heavier” over the winter. Nobody had touched the balance. That entry hides the real problem. An industrial door is never meant to feel heavy, because an industrial door counterweight system or its spring ... <a title="Industrial Door Counterweight Systems: How They Balance" class="read-more" href="https://www.raxdoors.com/blog/industrial-door-counterweight-balance/" aria-label="Read more about Industrial Door Counterweight Systems: How They Balance">Read more</a>

Guide Rails and Brackets for Industrial Doors

A door that was commissioned three months ago starts grinding at the same point of travel. The maintenance log already reads replaced rollers twice, the spring balance was re-checked, and the work order still has no line for the guide rails. Nobody has put a level on them, so the door keeps wearing out rollers ... <a title="Guide Rails and Brackets for Industrial Doors" class="read-more" href="https://www.raxdoors.com/blog/industrial-door-guide-rail-brackets/" aria-label="Read more about Guide Rails and Brackets for Industrial Doors">Read more</a>

Industrial Door Bottom Seals: Fit, Wear and Replacement

A sectional door closes at the end of the shift, and a bright strip of daylight still runs along the floor beneath it. By morning there is a dust line on the slab, a wet patch after the first rain, and a supervisor asking whether the floor has settled again. The panels get inspected, the ... <a title="Industrial Door Bottom Seals: Fit, Wear and Replacement" class="read-more" href="https://www.raxdoors.com/blog/industrial-door-bottom-seals-guide/" aria-label="Read more about Industrial Door Bottom Seals: Fit, Wear and Replacement">Read more</a>

Industrial Door Hinges: Types, Wear and Replacement

A loading dock door starts to bite its latch. The lock side has dropped half an inch, and the top edge scrapes the frame head every cycle. Nobody suspects the two pieces of steel holding the whole leaf: the hinges. The delay is expensive, because a sagging door points to worn hinge knuckles or pins, ... <a title="Industrial Door Hinges: Types, Wear and Replacement" class="read-more" href="https://www.raxdoors.com/blog/industrial-door-hinges-guide/" aria-label="Read more about Industrial Door Hinges: Types, Wear and Replacement">Read more</a>

Industrial Door Tracks and Rollers: A Working Guide

The call comes at two in the morning. A sectional door is stuck two thirds of the way up its guide track. A forklift is queued behind it, and the maintenance supervisor asks one question before any other: is it the roller or the track. Ordering the wrong side means a second downtime event to ... <a title="Industrial Door Tracks and Rollers: A Working Guide" class="read-more" href="https://www.raxdoors.com/blog/industrial-door-tracks-rollers-guide/" aria-label="Read more about Industrial Door Tracks and Rollers: A Working Guide">Read more</a>

Industrial Door Torsion Springs: An Overview for Buyers

A crate of springs arrives on a loading dock, and the delivery note says the part number was copied straight from the old door. The depot fits one, winds it, and the door slams down hard enough to shake the track brackets. Nothing was wrong with the spring; the order was wrong, because nobody on ... <a title="Industrial Door Torsion Springs: An Overview for Buyers" class="read-more" href="https://www.raxdoors.com/blog/industrial-door-torsion-springs-overview/" aria-label="Read more about Industrial Door Torsion Springs: An Overview for Buyers">Read more</a>

Industrial Door Springs: Types, Performance, Uses

A torsion spring is the only component on an industrial door that ships with its own odometer. The cycle rating stamped on the wire counts down every time the door moves, yet most facilities never read it until the door dies half open over a busy dock. The motor gets the blame, and the worn ... <a title="Industrial Door Springs: Types, Performance, Uses" class="read-more" href="https://www.raxdoors.com/blog/industrial-door-springs-guide/" aria-label="Read more about Industrial Door Springs: Types, Performance, Uses">Read more</a>
