Articulating booms bend. Telescopic booms (stick booms) shoot in a straight line. That single difference decides whether you can work over a parapet from the parking lot or whether you need a clear shot at the work from farther away. Height class is the second question, not the first.

Quick comparison
Articulating boom
Up-and-over access from a tight or obstructed setup.
Strengths
- Reaches over parapets and equipment
- Parks closer to the building
- Jib options for fine positioning
Watch-outs
- Less max outreach than a stick
- More joints to manage for new operators
Best for
- • Rooftop mechanical
- • Industrial interiors with obstacles
- • Tree and sign work over objects
Telescopic boom
Maximum straight-line height and outreach on an open setup.
Strengths
- Longer horizontal reach
- Faster to a far work point
- Simple geometry on open facades
Watch-outs
- Cannot knuckle over obstacles
- Needs a clear setup lane
Best for
- • Steel and tilt-up
- • Long building faces
- • Open-site high work

| Typical rental heights here | 45–46, 63, 80 ft classes | 40, 45, 60–66 ft classes |

Figures below are typical ranges for this equipment class — not a spec sheet for one serial-numbered unit. Used rental inventory rotates; we confirm height, capacity, width, and weight on your quote.
Articulating (knuckle) booms
Machines like a 45–46 ft articulating with jib, a 63 ft articulating, or a Genie Z-80/60 exist to reach up and over. Rooftop units, theater grids, industrial mezzanines, and trees are classic jobs. You can park closer to the building and still get the basket to a point that is not in a straight line from the turret. You give up some maximum outreach compared with a stick of similar height.
Telescopic (stick) booms
A 40 ft, 45 ft, or 60–66 ft telescopic boom is the faster machine when you can set up with a clear path — tilt-wall, steel, stadium lighting, long facades. Stick booms typically win on horizontal reach at a given height. They do not “knuckle” over a roof edge. If the only parking is on the far side of a canopy, you wanted articulating.
Jibs and range charts
A jib is extra wrist at the end of the boom. It is not free: capacity can drop and the range chart still rules. If your work is 40 ft up and 30 ft out, do not rent a 45 ft articulating and hope. Bring the numbers; we will check the chart for the class we send.
Who should rent which
Articulating for up-and-over and cluttered sites. Telescopic for open outreach and speed. Then pick height with the 40 vs 60 and 60 vs 80 guides. Call (801) 880-8800 with height, offset, and what sits between the machine and the work.
FAQ
Is a Z-80/60 a telescopic boom?
No. The Genie Z-80/60 is an articulating boom in the 80 ft class. Stick booms in our fleet are the S-40/S-45/S-65 and Skyjack “T” classes.
Do I still need a harness on both?
Yes. Boom lifts require a harness and lanyard to the manufacturer’s anchor, articulating or telescopic.
Can I put a glazier kit on either?
If the machine and capacity allow it. Glass is a capacity and wind problem — tell us the pane weight.
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.

Call or text — we'll match height, width, and capacity to the job instead of renting you a bigger machine than you need.
