Boom Lift Size Guide: What Size Boom Lift Do I Need for My Job?
Choosing the right boom lift starts with more than asking how high you need to go. The correct machine also depends on horizontal reach, platform capacity, terrain, access, power source, and whether you need a telescopic or articulating boom lift.
Boom lifts range from compact machines for commercial maintenance to 100-foot-plus boom lifts designed for major construction, industrial facilities, steel erection, infrastructure, and other high-reach applications.
Leading boom lift manufacturers include Genie, JLG, Niftylift, Skyjack, Haulotte, JCB, and other major aerial equipment manufacturers. JCB has expanded its powered-access lineup with electric, hybrid, and diesel boom lifts, adding another manufacturer for contractors and fleet owners to compare.
This boom lift size guide explains the most common boom lift sizes, how platform height differs from working height, and what specifications matter when choosing the right boom lift for your job.
What Size Boom Lift Do I Need?
Start with four basic questions:
- How high is the work area?
- How far horizontally do you need to reach?
- Are there obstacles between the machine and the work area?
- What type of terrain will the boom lift operate on?
The tallest boom lift is not automatically the best machine for the job.
A properly sized boom lift should provide enough platform height, working height, and horizontal reach while still fitting the jobsite, terrain, access restrictions, and type of work being performed.
Platform Height vs. Working Height
One of the most important boom lift specifications to understand is the difference between platform height and working height.
Platform height is the maximum height of the platform floor.
Working height estimates how high an operator can reach while standing in the platform. As a general rule, working height is approximately 6 feet higher than platform height.
When comparing boom lift sizes, always determine whether a listed specification refers to platform height or working height.
Common Boom Lift Sizes
40 Foot Boom Lifts
A 40 foot boom lift provides approximately 46 feet of working height and is a popular option for commercial maintenance, building exteriors, electrical work, signage, lighting, painting, and lower construction applications.
Common models include the Genie S-40 and S-40 XC, JLG 400S, and Niftylift TM40S.
For contractors who regularly work on lower commercial structures but still need meaningful horizontal reach, the 40-foot class can provide a good balance between reach and overall machine size.
45 Foot Boom Lifts
A 45 foot boom lift provides approximately 51 feet of working height and is one of the most versatile size classes for construction and maintenance.
Common applications include commercial buildings, warehouses, structural work, signage, electrical work, lighting, property maintenance, and exterior construction.
Examples include the Genie S-45 and S-45 XC, JLG 450AJ, Niftylift SP45E and SP45 4x4, and JCB A45E and A45EH.
The JCB A45E is a battery-electric articulating boom, while the A45EH uses a hybrid power system. Both provide a 45-foot-3-inch maximum platform height and a 660-pound unrestricted platform capacity.
60 Foot Boom Lifts
The 60 foot boom lift is one of the most versatile boom lift size classes in construction equipment.
With approximately 66 feet of working height, these machines provide considerably more height and horizontal outreach while remaining manageable on many commercial and industrial jobsites.
Popular examples include the Genie S-60 and S-60 XC, JLG 600S, Niftylift SP64E and SP64 4x4, and JCB A60E and A60EH.
JCB's newer A60E and A60EH articulating boom lifts expand its access-equipment range into the 60-foot class. The A60E uses an electric drivetrain, while the A60EH combines electric operation with an engine for extended runtime. JCB lists approximately 60 feet of platform height, along with both unrestricted and higher restricted platform capacities. Availability may vary by market.
The 60-foot class is frequently used for steel construction, industrial maintenance, warehouses, building exteriors, signage, mechanical work, and other applications where both height and outreach are important.
65 Foot Boom Lifts
A 65 foot boom lift provides approximately 71 feet of working height and is commonly used for larger commercial construction, industrial maintenance, steel erection, roofing, infrastructure, and high-access projects.
Popular models include the Genie S-65 and S-65 XC, JLG 660SJ, Niftylift SP65SE, and JCB T65D.
The JCB T65D is JCB's diesel telescopic boom lift in this class. It provides approximately 65 feet 4 inches of platform height, 71 feet 11 inches of working height, and 56 feet 6 inches of horizontal outreach.
JCB also rates the T65D for 661 pounds throughout the full working envelope and up to 1,000 pounds within a restricted portion of the envelope, making it another high-capacity option for contractors who regularly carry additional workers, tools, or materials.
80 Foot Boom Lifts
An 80 foot boom lift provides approximately 86 feet of working height and significantly more horizontal reach than smaller machines.
These boom lifts are commonly found on large commercial construction projects, industrial sites, warehouses, manufacturing facilities, infrastructure projects, stadiums, and large building exteriors.
Examples include the Genie S-80, Genie S-80 J, and JLG 800S.
At this height, transportation requirements, machine weight, turning radius, ground conditions, and jobsite access become increasingly important parts of the buying decision.
85 Foot Boom Lifts
A typical 85 foot boom lift provides approximately 91 feet of working height.
This class is well suited for high-rise exterior work, industrial maintenance, large commercial facilities, steel erection, mechanical systems, and applications requiring substantial horizontal outreach.
Examples include the Genie S-85 and S-85 XC, JLG 860SJ, and Niftylift SP85 4x4.
100 Foot and Larger Boom Lifts
For extreme reach applications, manufacturers offer 100 foot, 120 foot, 135 foot, 150 foot, and even 180 foot boom lifts.
Examples include:
Genie: SX-105 XC, SX-125 XC, SX-135 XC, SX-150, SX-180
JLG: 1200SJP, 1350SJP, 1500SJ, 1850SJ
These machines are designed for major construction projects, industrial plants, stadiums, infrastructure, large distribution centers, power facilities, and other applications where extreme platform height and horizontal reach are required.
These are common examples rather than a complete list of every boom lift available. Manufacturer lineups, specifications, and regional availability can change, so always verify the exact model and configuration before purchasing.
Horizontal Reach Matters as Much as Height
One of the most common mistakes when choosing a boom lift is focusing only on how high the machine goes.
Horizontal reach, sometimes called horizontal outreach, determines how far the platform can extend away from the machine.
Imagine the work area is 60 feet high, but the boom lift must sit 35 feet away because of landscaping, equipment, a building setback, a loading dock, or another obstruction.
Platform height alone does not tell you whether the machine can reach that location.
Before purchasing a boom lift, determine both:
How high do you need to reach?
How far away will the machine need to be positioned?
The machine's reach chart or working envelope is often more useful than a single maximum-height specification.
Telescopic vs. Articulating Boom Lift
Another major decision is choosing between a telescopic boom lift and an articulating boom lift.
Telescopic Boom Lift
A telescopic boom lift, also commonly called a straight boom lift, extends primarily outward and upward in a relatively direct line.
These machines are a strong choice when you need:
- Maximum horizontal reach
- Fast positioning
- Open access to the work area
- High platform heights
- Large outdoor working envelopes
Models such as the Genie S-60, Genie S-65, JLG 600S, JLG 660SJ, and JCB T65D are examples of telescopic boom lifts.
Straight booms are especially useful when there is a relatively clear path from the machine to the work area and horizontal outreach is a priority.
Articulating Boom Lift
An articulating boom lift uses multiple boom sections that bend or articulate.
This gives the machine the ability to position the platform up and over obstacles.
Articulating boom lifts are commonly used around:
- Buildings
- Rooflines
- Structural components
- Industrial equipment
- Mechanical systems
- Signage
- Warehouses
- Congested jobsites
Models such as the JLG 450AJ, JCB A45E, JCB A45EH, JCB A60E, and JCB A60EH fall into the articulating boom category.
If something blocks a direct path between the machine and the work area, an articulating boom may provide better access than a comparable straight boom.
Consider Platform Capacity
Platform capacity determines how much combined operator, tool, equipment, and approved material weight the platform can carry.
This specification deserves more attention than it often receives.
A standard platform capacity may be perfectly adequate for routine elevated work. Other applications involve multiple workers, welders, tools, equipment, or heavier materials and can benefit from a high-capacity boom lift.
Restricted vs. Unrestricted Platform Capacity
This distinction is important when comparing high-capacity boom lifts.
Unrestricted capacity means the machine can carry that rated load throughout its approved working envelope.
Restricted capacity means the higher load is available only within a specified portion of the working envelope.
That means the largest capacity number on a specification sheet does not necessarily tell the whole story.
When comparing a Genie XC boom lift, JLG HC or HC3 boom lift, JCB high-capacity boom, or another increased-capacity machine, consider:
- Unrestricted platform capacity
- Restricted platform capacity
- Number of operators
- Weight of tools and materials
- Required platform height
- Required horizontal outreach
- Where the higher-capacity working zone is available
For certain crews, platform capacity can be just as important as platform height.
Do You Need a Jib?
A boom lift jib is the smaller articulating section near the platform at the end of the main boom.
It may not add a dramatic amount of overall reach, but it can make positioning the basket considerably easier.
A jib is especially useful when working around:
- Roof edges
- Structural steel
- Mechanical systems
- Signs
- Building corners
- Overhead obstacles
When comparing two boom lifts with similar height and reach, the amount of jib articulation can affect how effectively the operator can position the platform at the final work point.
Platform Rotation Can Make a Big Difference
Another specification buyers sometimes overlook is platform rotation.
A platform rotator allows the basket to rotate horizontally at the end of the boom.
That can help an operator line up with a wall, structural component, sign, piece of equipment, or other work area without repositioning the entire boom lift.
For jobs that require frequent precise positioning, this seemingly small feature can have a noticeable effect on productivity.
