# What Size Scissor Lift Do I Need? Working Height Explained

Quick answer: measure the height of the actual work point, then choose the smallest machine whose working height covers it and that also fits your narrowest access point and your floor. The "19ft" or "26ft" in a scissor lift's name is its size class, which describes the platform height, not the working height. Width, floor loading and the surface rule out more machines than height does.

## Feet classes versus working height

- Platform height is where the deck floor sits at full elevation. The feet class in a machine's name describes this figure: a 19ft class machine has a platform at about 5.8 m.
- Working height is platform height plus about 2 m for a person standing on the deck. Plan against this figure.

So a 19ft class machine gives roughly 7.8 m working height. Do not add your own reach on top, because it is already in the working height. Measure the work point itself (the cable tray, the fitting, the sign) and choose a machine that covers it with a sensible margin. The working height vs platform height guide explains the two figures in more detail.

## Heights on the current fleet

The table below is read from the verified machine records, so it changes when the fleet does.

Each machine page carries the manufacturer specification sheet. Confirm the figures for the exact machine before you book.

## Indoor and outdoor limits

Many scissor lifts carry a lower rating outdoors than indoors, because wind changes what the machine may safely do. The outdoor rating can mean less height, fewer people on the platform, or both. For example, the LGMG SC0610EL-2 is rated to 8.8 m working height indoors with up to two people, and 7.5 m outdoors with one person. If any part of the job is outside, plan to the outdoor figure for that machine.

## Width and doorways rule out more than height

Measure your narrowest access point (door, corridor, gate, lift car) and the stowed height on the way in before you settle on a height. Examples from the fleet:

- LGMG S0607E II: 0.79 m wide
- JLG ES1932: 0.81 m wide
- Zoomlion ZS0808AC: a 26ft class narrow machine; check its width and stowed height on the machine page against your opening
- LGMG S1212E-2: a 40ft class machine that needs a much wider opening and a clear travel path

A narrow machine is not guaranteed to fit a particular doorway. Measure the clear opening with the door open, any door closer or frame that projects, and the turn on either side, then compare those measurements with the machine's width and length. The scissor lift width and site access guide shows what to measure.

Ceilings cut the other way: the stowed height must clear the way in, and full elevation must clear sprinklers, lights and services above.

## Floor loading and weight

Bigger machines are much heavier, and the weight column in the table above shows how much. On suspended slabs, mezzanines and older floors, confirm the floor's rating before you hire a heavier unit. See ground conditions for access equipment and the floor loading guide linked from it.

## Surface and power

Sizing assumes the machine can actually stand at the work point:

- Firm, level indoor slab: a wheeled electric scissor lift is usually the right machine.
- Uneven ground, compacted fill or site ground: look at rough terrain or tracked machines, and tell us the surface. A slab machine is not built for it.
- Power: electric machines need a charging plan, and some tracked machines run on mains power or diesel. See electric vs diesel scissor lifts.

## Platform load and occupants

Platform capacity and the number of people allowed are set by each machine's plate, and they can differ indoors and outdoors. The extension deck always carries less than the main deck. Count people, tools and materials honestly against the plate for the machine you are hiring, not against a size class.

## Why "biggest just in case" backfires

Bigger machines cost more, weigh more, need wider access and are slower to reposition. Over-sizing adds floor load and manoeuvring risk without making the job faster. If you are between sizes, tell us the actual work-point height and we will tell you which machine covers it.

## Selection checklist

- Work-point height measured, not guessed from the building type
- Candidate machine's working height covers it with margin, using the outdoor figure if any work is outside
- Narrowest access point measured against the machine's width, and stowed height clears the way in
- Ceiling, sprinklers and services clear full elevation
- Floor rating checked against machine weight, especially suspended floors
- Surface known: slab, fill, uneven ground
- People, tools and materials within the plate for that machine
- Charging, mains power or refuelling plan for the hire

## FAQs

What does "19ft" mean on a scissor lift? It is the size class, which describes the platform height (about 5.8 m). Working height is about 2 m more.

Is a 19ft scissor lift enough for warehouse lights? Often for lower warehouse and retail lighting, but size from the actual fitting height. High-bay areas usually need a larger class.

Should I size to the highest point on site? Size to the real task areas. If one task is much higher, a second machine for that task can cost less than one oversized machine for the whole job.

Will a narrow scissor lift fit through my door? Only measurement answers that. Compare the clear opening and the turns with the machine's width and length on its page.

Can I use a slab scissor lift outdoors? Some are rated for limited outdoor use, often with fewer people and a lower height. Check the machine's outdoor rating, and never set one up on soft or uneven ground.

When should I choose rough terrain or tracked instead? When the surface, or the route to the work area, is unsealed or uneven. See the tracked scissor lift hire guide.

What if the work point is off to the side? A scissor lift works directly overhead, plus its deck extension. Offset or up-and-over work is boom territory. See scissor lift vs boom lift.
