A boom lift reaches high and around obstacles in ways a straight ladder cannot
A boom lift — sometimes called a cherry picker, boom truck, or articulating lift — is a vehicle with a long arm that extends upward and outward to lift a worker or small load to a height. The arm bends in the middle (that bend is the articulation), so it can reach over obstacles, around corners of buildings, or into spaces a straight vertical lift cannot access. The operator controls the arm from a platform at the end, or from ground controls, depending on the model.
The vehicle itself is usually mounted on a truck chassis, a trailer, or a self-propelled base. A boom lift differs from a scissor lift — which goes straight up and down — because the boom can extend horizontally and bend. This makes it useful for work on the sides of buildings, in trees, on bridge work, or anywhere the work is not directly above the base of the machine.
Key Takeaways
- Boom lifts reach heights from 30 feet to over 150 feet depending on the model, and the arm can extend outward to reach work that is not directly overhead.
- Operating a boom lift requires training and often a certification, because the machine is heavy, the platform moves, and mistakes can cause serious injury or death.
- Boom lifts are rented by the day, week, or month from equipment rental companies, and rental cost depends on the height, reach, and how long you need it.
- Setup requires a flat, stable surface, enough space for the base and the extended arm, and sometimes outriggers or stabilizers to keep the machine from tipping.
- Common uses include building maintenance, tree trimming, electrical line work, signage installation, and construction work above ground level.
How boom lifts are classified by size and reach
Boom lifts come in different sizes, and the size determines how high they reach and how far out the arm extends. A small boom lift might reach 30 to 40 feet and extend 20 feet horizontally. A large boom lift can reach 150 feet or more and extend 60 feet or more from the base. The height and reach you need depend on the job — a tree trimming job on a residential street needs less reach than work on a multi-story building or a bridge.
Boom lifts are also classified by whether they are truck-mounted, trailer-mounted, or self-propelled. A truck-mounted boom is bolted to a truck chassis and moves with the truck. A trailer boom is towed behind a vehicle. A self-propelled boom has its own engine and wheels, so it can move around the job site under its own power. Self-propelled booms are slower but do not require a separate truck or towing vehicle.
The weight capacity of the platform also varies. Most booms carry one or two workers plus tools, but some are rated for heavier loads. The rental company will tell you the weight limit for the specific machine you are renting.
Operator training and certification requirements
Operating a boom lift is not a casual task. Most states and many job sites require the operator to hold a certification showing they have been trained on the specific type of lift. The certification is usually issued by the equipment manufacturer or by an accredited training organization, and it typically involves classroom instruction and hands-on practice.
Training covers how to inspect the machine before use, how to operate the controls safely, how to recognize hazards like power lines or unstable ground, and what to do if something goes wrong. The operator learns the weight limits, the reach limits, and the conditions under which the machine should not be used — such as in high wind or on a slope.
If you do not have a certification, you can hire a certified operator to run the machine, or you can take a training course before you rent. Many rental companies offer training or can recommend a training provider. The cost of training is separate from the rental cost.
Renting a boom lift and what to expect on delivery
Boom lifts are rented from equipment rental companies, not purchased for one-time use. You can rent by the day, week, or month. Daily rates vary widely depending on the size of the boom, your location, and current demand, but a small boom might cost $200 to $400 per day, and a large boom might cost $500 to $1,000 or more per day. Weekly and monthly rates are usually lower per day than daily rates.
When you contact a rental company, tell them the height you need to reach, how far out the arm needs to extend, how much weight the platform will carry, and how long you need the machine. The rental company will recommend a model and give you a price. They will also ask about the job site — whether the ground is level, whether there are power lines nearby, and whether you have a certified operator or need to hire one.
Delivery usually takes one to three days after you place the order, depending on the rental company's schedule and your location. The company will deliver the boom to your site, and a technician will set it up, test it, and show you or your operator how to use it. Setup can take an hour or more, depending on the complexity of the machine and the site conditions.
Site preparation and safety setup
Before a boom lift can operate, the job site must be prepared. The ground must be level and stable — soft ground, gravel, or slopes can cause the machine to tip. If the ground is not stable, you may need to place steel plates or mats under the wheels or outriggers to spread the weight.
Outriggers are legs that extend from the sides of the machine to prevent tipping when the boom is extended. Most booms require the outriggers to be fully extended and locked before the boom can be raised. The rental company will explain how to set the outriggers for your specific site.
You also need to check for hazards around the work area. Power lines are the most serious hazard — a boom or the person on the platform can conduct electricity if they touch a live line. The operator must maintain a safe distance from all power lines. Other hazards include buildings, trees, vehicles, and pedestrians. The area around the boom should be cordoned off so no one can walk into the path of the extended arm.
Common uses for boom lifts on job sites
Boom lifts are used for many types of work. Building maintenance and repair — such as cleaning windows, repairing facades, or painting — is one of the most common uses. Tree trimming and removal often uses boom lifts because the arm can reach into the canopy and position the worker safely.
Electrical work, such as installing or repairing power lines, street lights, or traffic signals, frequently uses boom lifts. Signage installation — putting up large signs on buildings or along highways — is another common process. Construction work, such as installing roof trusses, exterior walls, or HVAC equipment, often requires a boom lift to position workers and materials at height.
Boom lifts are also used for inspection work, such as bridge inspections or building surveys, where a worker needs to reach a specific spot and stay there for a period of time. The platform of a boom lift is more stable and comfortable for extended work than a ladder or a rope system.
Boom lifts versus other lifting equipment
A boom lift is not the only way to reach high places. A scissor lift goes straight up and down and is useful when the work is directly above the base. A scissor lift is usually cheaper to rent and takes up less space, but it cannot reach around obstacles or extend horizontally. A ladder or scaffolding can be used for lower heights but requires more setup time and is less stable for extended work.
A personnel lift or man lift is a smaller, lighter version of a boom lift, often used indoors or in tight spaces. A crane is used for heavier loads and greater heights but is more expensive and requires more setup. A rope and harness system can reach almost anywhere but requires trained climbers and is slower than a mechanical lift.
The choice of equipment depends on the height, the reach, the weight to be lifted, the duration of the work, the site conditions, and the budget. The rental company can help you choose the right equipment for your job.
Frequently Asked Questions
Do I need a special license to operate a boom lift?
A boom lift does not require a driver's license, but most job sites and many states require a certification from the equipment manufacturer or an accredited trainer. The certification shows you have been trained on that type of machine. If you do not have one, you can hire a certified operator or take a training course.
Can a boom lift work in the rain or high wind?
Most boom lifts should not be operated in high wind — the rental company will tell you the wind speed limit for the specific machine. Rain is usually acceptable if the platform has good traction and the operator can see clearly. Always check with the rental company and follow the manufacturer's guidelines for your job site conditions.
What happens if the boom lift tips or fails?
Boom lifts have safety systems, including load sensors, tilt alarms, and emergency descent controls. If the machine tips or loses power, the operator can manually lower the platform to the ground using a hand pump or emergency valve. This is why training and regular inspection are critical — failures are rare if the machine is maintained and operated correctly.
Can I rent a boom lift for just a few hours?
Most rental companies have a minimum rental period of one day, even if you only need the machine for a few hours. Some companies may offer half-day rates, but this is less common. Ask the rental company about their minimum rental period and whether they offer shorter-term options.
What is the difference between a boom lift and a bucket truck?
A bucket truck is a smaller boom lift mounted on a utility truck, often used by power companies and tree services. A bucket truck usually reaches 40 to 60 feet and is designed for one worker. A boom lift is larger and can reach higher and farther, and some models carry two workers or small loads. Bucket trucks are faster to deploy but have less reach and capacity.
