Renting a Boom Lift for Sign and Banner Installation

The new storefront letters mount 20 feet up on a fascia that sits behind an awning, or the 30-foot banner has to span the building face for the weekend, and the sidewalk and the parking lot are right below either one. A ladder is not an option at that height, and a scissor lift cannot park under the awning. Renting a boom lift for sign installation is how the job gets done, and the right machine depends on what sits between where you can park and where the sign mounts. Here is how to choose articulating versus telescopic, size the height and reach to the mount, work within the platform's capacity with a sign on board, handle wind on a banner, keep clear of power lines, and secure the ground below.

Why signage needs a boom, not a scissor

Signs mount on fascias, parapets and walls that are usually above or behind an obstacle, so the platform has to go up and over, which is what a boom lift does and a scissor lift cannot. Straight-up reach is rarely enough for a sign.

Awnings, canopies, entry roofs, landscaping beds and parked cars all sit between where a machine can park and where the sign goes, and a boom reaches past them while a scissor lift only works when it can park directly below the mount on a flat, clear surface. The exception is interior signage in a mall or a lobby, where a scissor or a one-person lift often does fit. Read more about a scissor lift versus a boom lift; the job is different but the logic is the same.

Articulating or telescopic

An articulating boom bends to reach up and over an obstacle and in to the wall, which suits most storefront and building-face signs. A telescopic boom reaches straight out and very high, which suits tall pylons, towers and open faces. Pick by what is between the machine and the mount.

The articulating, or knuckle, boom is the sign installer's usual choice because it can rise over an awning or a parapet and then position the platform flat against the fascia where the work is. The telescopic, or stick, boom gives the most height and horizontal reach on an open face where nothing is in the way, which is a pylon sign or a tall blank wall. Both come electric, which is quiet, exhaust-free and non-marking for pavement and indoor work, and diesel, which handles rough ground and offers four-wheel drive. For storefront work on pavement, an electric articulating boom is the common answer. Route sizes and configurations to the listing.

Size height and reach to the mount

Measure the mounting height, the horizontal distance from where the machine can park to the wall, and the height of whatever sits in between, then pick a lift whose working height and outreach cover all three with margin. Platform height is not the same as the height you can work at.

Working height is usually the platform height plus about 6 feet, the reach of a standing worker, so compare that figure, not the platform height, to where the sign mounts. Then check horizontal outreach from the machine's realistic parking spot to the fascia, remembering that on most booms the outreach shrinks as the platform rises, so read the range diagram rather than the headline numbers. Finally, confirm the up-and-over clearance past the awning or parapet. Measure the site with a tape and a laser; do not estimate from across the parking lot.

Platform capacity: people plus the sign

The platform rating has to cover everyone on it plus the sign, the hardware and the tools, and a set of channel letters with a raceway or a cabinet sign adds up faster than people expect. Capacity is the number that gets ignored on sign jobs, and it is the one that tips a boom.

Common boom platforms are rated somewhere in the 500- to 1,000-pound range depending on the machine and the configuration, and two installers with tools can use most of the lower figure before the sign goes up. Weigh the sign and the hardware, add the people and the tools, and compare to the placard. For a heavy cabinet, plan a separate lift, a telehandler with a jib or a crane, and use the boom to position and fasten rather than to carry. Never hang anything from the rails or the boom, and check whether the platform rating changes with the jib extended or at full reach. Your harness and lanyard clip to the platform's anchor point whenever the lift is in use. Read more about what fall protection you need on a rented boom lift.

Wind on a banner

A banner is a sail, and unfurling one at height on a windy day loads the platform and the boom far beyond what the machine's wind rating assumes, so check the rating, check the forecast and keep the banner furled until it is anchored. Signs with large flat faces do the same thing.

Outdoor boom lifts carry a maximum wind rating, commonly 28 miles per hour, that assumes a bare platform, and most manufacturers restrict or prohibit handling sheet materials in wind for exactly this reason. The method that works is to keep the banner rolled on the way up, anchor the top edge first, then unroll and anchor it section by section with a helper on the ground managing the lines. Wind is stronger at the mount than on the sidewalk, and a gust is what moves a machine, so stop and come down when the wind picks up rather than finishing the last corner. Read more about how wind affects boom lift operation and when to stop.

Power lines, sidewalks and the ground below

Fascias and building faces often have service drops and overhead lines nearby, and the ground below is a sidewalk or a parking lot, so the two site hazards are electrical contact and whatever you drop. Both get planned before the boom goes up.

Look up before you set up. Keep the platform, the boom, the sign and every tool at least 10 feet from any overhead line, more at higher voltage, and if the mount is closer than that, call the utility before you rent anything. Set the machine on firm, level ground, deploy outriggers where the machine has them, and chock the wheels. Cone or barricade the sidewalk and the parking spaces beneath the work, because a dropped letter or a drill from 25 feet is a serious injury to someone who never looked up. And check whether your city requires a sidewalk-closure or encroachment permit for the hours you will be working over public space.

Indoor and mall signage

For interior signage in a mall, a lobby or a big-box store, an electric lift with non-marking tires that fits through the door is the answer, and often a scissor or a one-person lift does the job a boom would overdo. Different rules apply inside.

Check doorway and elevator fit, floor loading and the center's rules on after-hours work, which most require. A compact electric articulating boom earns its place indoors when the sign hangs over fixtures or a storefront bulkhead a scissor cannot reach past.

What about insurance and damage protection?

Before operating rented equipment, contact your insurance provider to ask whether your policy covers liability for heavy equipment operation on your property or job site.

Eligible rentals booked through Big Rentals also include Basic Rental Protection at checkout. This added protection can help limit your financial responsibility for certain damage or theft events during the rental period.

For full details on how Basic Rental Protection works, including deductibles, exclusions and renter responsibilities, review our FAQ and platform terms.

The Short Version

• Signs mount above or behind awnings, parapets and cars, so you need a boom that goes up and over, not a scissor that only goes up
• Articulating booms suit storefronts and building faces; telescopic booms suit pylons and open walls; electric for pavement and indoors
• Size by working height (platform plus about 6 feet), outreach at height, and up-and-over clearance, measured on site
• Platform ratings run roughly 500 to 1,000 pounds; weigh the sign plus people and tools, and lift heavy cabinets separately
• A banner is a sail: respect the wind rating, keep it furled until anchored, and come down when gusts pick up
• Stay 10 feet from power lines, set up on level ground with outriggers and chocks, and cone off the sidewalk and spaces below
