A 40–45 ft boom (Genie S-40/S-45, Skyjack SJ40, 45 ft articulating) is the everyday exterior rental. A 60–66 ft stick (S-65 class, SJ61T/SJ66T) is for work that a 45 simply cannot chart. The jump is expensive in rate and in trucking — do not buy it as a comfort blanket.

- Enough for most two-story work
- Articulating and telescopic options
Watch-outs
- Range chart fails on taller walls at outreach
- Not a 60 ft substitute
Best for

- • Light mechanical
- • Painting and signage at modest height
60–66 ft boom
The step-up stick class for real commercial height and outreach.
Strengths
- Working height and outreach that 45 ft cannot fake
- Better for steel and warehouse walls
- S-65 / SJ66T class familiarity
Watch-outs
- Higher rental and trucking
- Needs more room to set up
- Overkill for a 24 ft eave
Best for
- • Three-story exteriors
- • Steel erection support
- • Jobs with large standoff distances
| Spec | 40–45 ft boom | 60–66 ft boom |
|---|---|---|
| Nominal height class | 40–45 ft | 60–66 ft |

What 40–45 ft actually reaches
Two-story facades, storefronts, many church exteriors, and a lot of mechanical on low-slope roofs if you can get the machine close. Articulating 45–46 ft with a jib is often more useful than a 40 ft stick on a cluttered site even if the brochure height is similar.
When 60–66 ft is the honest answer
Three-story work, warehouse exteriors, steel that sits far off the pad, and any job where the 45 ft range chart leaves you 8 feet short. Genie S-65 XC class and Skyjack 61/66T class are the common rental answers. Outreach at height is why people miss — you may need 60 ft of machine to hold 45 ft of height at 30 ft of reach.
Delivery and site size
60 ft class machines are longer, heavier, and need more room to unload. If the lot is a downtown pad with a 20-foot gate, talk to us before you order the bigger boom. Sometimes an articulating 63 ft or a different setup angle beats brute height.
Who should rent which
Stay in 40–45 ft if the work is two stories and you can park close. Move to 60–66 ft when the chart says the 45 cannot do it. Call (801) 880-8800 with wall height and how far you can park from the building.
FAQ
Is a 45 ft boom enough for a 40 ft wall?
If you can park against the wall, maybe. If you must stay 20 ft back for landscaping or power lines, it may not chart. Measure standoff.
Articulating 63 ft or telescopic 66 ft?
Obstacles = articulating. Open facade and max outreach = telescopic. See the geometry guide.
Can I trailer a 60 ft boom myself?
Usually no. These go on our truck. Towable booms are a different product (T350/T500 class).
Machines on the lot
Live inventory rotates. These are current machines in the related rental collections — not a promise that a specific used unit is still here.
