A Guide To Boom Lift Rentals for Electrical and Overhead Line Work

Electrical and overhead line work happens up high and often out of easy reach: a service drop at the weatherhead, parking lot lights, an overhead conduit run. A ladder won't get you there safely, and a scissor lift only goes straight up.

Reaching those spots means getting a worker and their tools to height, sometimes out over an obstacle, and doing it near power lines where a mistake is serious.

A boom lift is the tool for that reach. This guide covers renting one for overhead and electrical work, choosing the right boom type and working safely near lines.

What a Boom Lift Does for Overhead Work

A boom lift raises a worker in a platform to height, and unlike a scissor lift, it can reach out horizontally and around obstacles to a work point. That reach is what gets a worker to a service drop, an overhead light or a high conduit run that a ladder can't reach safely and a scissor lift can't get out to.

The platform carries the worker plus tools and some material, so the work happens at height instead of from a ladder you keep climbing down to reprovision. Done right, that's steadier and faster than working overhead off a ladder. You'll also hear a boom lift called a cherry picker or man lift; it's built to position one worker precisely where the work is, not to move heavy loads, so match it to access work rather than material handling.

Articulating vs Straight Boom

Straight (telescopic) boom: maximum reach in a line

A telescopic, or straight, boom extends in a straight line for the most height and horizontal reach. It's the pick when you can position the base with a clear, open line to the work: tall parking lot lights, long overhead runs and open sites where nothing's in the way. A straight boom needs more room to set up, and often outriggers, so it wants space around the base.

Articulating boom: up and over obstacles

An articulating, or knuckle, boom has jointed sections that reach up and over obstacles and into tight spots. It's the pick for congested sites and up-and-over access: reaching over a building edge, around structures or past landscaping to get to a service drop. It's the more maneuverable of the two where space is tight.

Which one for your job

The short rule: open and far means straight, while over or around an obstacle means articulating. If you're deciding among lift types more broadly, read more about how to choose the right lift for your project.

Common Overhead and Electrical Jobs

Service drops and masts

Reaching the weatherhead, mast and connection point where an overhead service drop meets a building. The boom positions the worker at the connection while keeping the platform clear of the utility's energized conductors. This is customer-side work on the mast, weatherhead and service entrance, and depending on where the utility's responsibility ends, some of it may need to be coordinated with the power company first.

Overhead lighting

Installing, relamping and servicing parking lot and area lights, high-bay fixtures and building-mounted lighting that sits too high to reach from the ground. For lights inside a facility, an electric model keeps the work quiet and fume-free.

Overhead runs and signage

Running and supporting overhead conduit, cable and festoon, and installing or servicing signage that's out of a ladder's range.

Sizing the Lift

Height and reach

Match the boom's working height to how high you need to reach, and its horizontal outreach to how far the work sits from where the base can go. Working height is higher than platform height, since it counts a worker's reach from the platform, so check which number the listing is quoting. If the work calls for fine positioning at the end of the reach, look for a model with a jib.

Capacity and terrain

Confirm the platform capacity covers the worker plus tools and any material. Pick a rough-terrain unit for uneven outdoor ground and a smaller electric one for smooth indoor floors, since diesel machines aren't suited to enclosed spaces. Check the setup footprint too, since some booms deploy outriggers and need clear, level space around the base, and for outdoor sites four-wheel drive helps a rough-terrain unit reach the work across the ground.

Working Safely Near Power Lines

A standard boom lift is not insulated

A standard rental boom lift is not an insulated aerial device, and it offers no protection against electrical contact. Work on or in direct contact with energized lines is for qualified line workers using rated, insulated equipment, not a general-purpose rental lift.

Keep your distance and treat every line as live

Maintain the required safe clearance, the minimum approach distance, from energized power lines at all times, and treat every line as live unless it's confirmed otherwise. That clearance applies to the whole machine and everything in the platform, including tools and material you're handling, not just your body. Where you can, have the line de-energized and coordinate with the utility before working near it.

Look up, and use qualified people and a spotter

Look up and locate every overhead line before you position the lift, and keep watching them as you move the boom, since contact usually happens during positioning. Operating an aerial lift requires training and authorization, so use qualified operators, a ground spotter and clear communication throughout.

The rest of the basics

Wear fall protection tied off to the platform, stay inside the rails, don't exceed the platform capacity, set up on firm level ground away from soft spots, holes and drop-offs, and don't operate in high wind. Wind limits are lower up high than they feel at ground level, so check the machine's rated wind speed and come down if it turns gusty. Inspect the machine before each use, and know where the ground-level emergency lowering controls are so someone can bring the platform down if they need to.

Getting It to Your Site

Boom lifts are heavy and are often delivered, so many renters have the machine dropped at the site rather than hauling it themselves. They range widely in size, and larger models run well into the tens of thousands of pounds, which is part of why delivery is common. If you are moving it, use a trailer rated for its full weight and secure it properly for the drive. Read more about how to load a trailer for securing.

What about insurance and damage protection?

Before towing a rented trailer, contact your auto insurance provider to ask whether your policy covers liability and towing-related damage claims.

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.

The Short Version

• A boom lift reaches up and out to overhead work a ladder can't reach safely and a scissor lift can't get out to
• A straight, telescopic boom gives the most reach in a clear line; an articulating boom reaches up and over obstacles and into tight spots
• Use it for service drops, overhead lighting, overhead conduit and cable runs, and high signage
• Size it by working height, horizontal outreach and platform capacity, and match the machine to the terrain
• Near power lines, a standard boom lift isn't insulated, so keep the required clearance, treat every line as live, de-energize and coordinate with the utility where you can, and use qualified operators and a spotter
• Wear fall protection, stay within capacity, set up level and don't operate in high wind
