A plain-language map of the aerial work platform (AWP) market: which type to choose for which height, which job and which site — with real models for scale.
Short Answer
Choose by how you get to the work: self-propelled boom lifts drive themselves around one site and top out below about 30 m; truck-mounted platforms mount on a commercial chassis and reach 30–65 m while travelling between sites at road speed; hybrid-boom truck mounts combine an articulated boom with a telescopic section to work over obstacles and below grade. If your work is spread across one plant or venue, buy self-propelled. If your crews serve many sites, buy truck-mounted.
| Type | Typical working height | Travels between sites | Example in our catalogue |
|---|---|---|---|
| Self-propelled electric boom lift | 22–29 m | By trailer | XGS28ACK-Li |
| Truck-mounted telescopic boom | up to 40 m | Yes, road-legal | GKS40A |
| Truck-mounted hybrid boom | up to 65 m | Yes, road-legal | GKH65 |
1. Self-Propelled Boom Lifts: The Site Workhorse
Self-propelled booms (straight or articulated) are battery-driven machines that drive, steer and elevate from the platform. They are the default for work concentrated in one location: venues, bridges, plant construction and maintenance.
In our catalogue, the XCMG XGS22ACK-Li reaches 22.9 m working height with 15.4 m outreach and up to 460 kg platform capacity, and the XGS28ACK-Li extends that to 28.8 m height with 22 m outreach. Both are offered with lithium battery drive; operating weights are 10,300 kg and 16,600 kg respectively, which matters for trailer selection and floor loading on indoor jobs.
Key selection points:
- Working height vs platform height: manufacturers quote working height (platform height plus ~2 m operator reach). Match it to your tallest task.
- Outreach: how far horizontally the boom carries you past obstacles.
- Platform capacity: whether the basket carries one worker with tools or two with materials (the XGS models above switch between 300 kg and 460 kg configurations).
2. Truck-Mounted Telescopic Booms: Reach at Road Speed
A truck-mounted platform puts the boom on a commercial truck chassis, so one crew and one machine serve an entire region. The XCMG GKS40A is a typical example: 40 m working height, 26.5 m outreach, 400 kg basket capacity, a 7-section synchronously telescoping boom and a Foton Cummins 156 kW chassis engine.
Truck mounts win when:
- your projects are geographically scattered;
- you need working heights beyond what self-propelled machines reach;
- road mobility between jobs is daily business.
Trade-offs: you need a licensed truck driver, stable outrigger set-up ground at each stop, and the working envelope is anchored to where the truck parks.
3. Hybrid Boom Truck Mounts: Over Obstacles and Below Grade
A hybrid boom combines an articulated (knuckle) section with telescoping sections in one boom. The XCMG GKH65 uses this structure to reach 65 m working height with 40 m outreach, 500 kg platform capacity, and a distinctive advantage: 14 m of below-ground working depth for bridge undersides, shafts and embankment work.
Choose hybrid boom when:
- the work point is behind or above obstacles a straight boom cannot clear;
- you need both high reach and down-reach in one machine;
- jobs include bridge inspection, facade work over canopies, or embankment maintenance.
4. Capacity, Load Charts and Platform Options
Across all types, three numbers decide whether the machine fits the task:
| Number | Why it matters |
|---|---|
| Platform capacity | Workers + tools + materials; exceeding it trips load-limiting systems |
| Outreach at load | Capacity drops as the boom extends; check the chart at your working geometry |
| Below-ground depth | Only hybrid/articulating types offer it — critical for bridges and shafts |
Modern machines add load-moment limiting, dual control stations, soft-leg detection and interlocks — treat these as baseline expectations for export fleets, not upgrades.
5. Chassis, Battery and Emissions Choices
- Self-propelled: battery options (lead-acid vs lithium — the XGS22ACK-Li offers both) affect runtime, charging speed and weight.
- Truck-mounted: the carrier chassis determines road licensing, parts availability and service network in your country — confirm chassis support before ordering. The GKS40A uses a Foton Cummins 156 kW engine; the GKH65 uses a Sinotruk 254 kW chassis.

Frequently Asked Questions
Q: What is the difference between a boom lift and a truck-mounted aerial platform?
A boom lift is self-propelled and battery-driven, working within one site at up to roughly 30 m. A truck-mounted platform carries its boom on a road-legal chassis, travels between sites at road speed and reaches 40–65 m. The GKS40A (40 m) and GKH65 (65 m) are truck-mounted examples.
Q: Which aerial platform type works below ground level?
Hybrid boom machines such as the XCMG GKH65 reach up to 14 m below grade, making them suitable for bridge undersides and shaft work. Straight telescopic booms generally do not offer below-ground reach.
Q: How high do self-propelled boom lifts go?
Typical self-propelled straight booms reach the high-20s of metres. The XCMG XGS28ACK-Li reaches 28.8 m working height with 22 m outreach; beyond that, truck-mounted platforms are the standard answer.
Q: What platform capacity do I need?
One operator with tools usually fits in a 230–300 kg basket; two operators or one with materials need 400–500 kg. The XGS22ACK-Li and XGS28ACK-Li offer 300/460 kg configurations, the GKS40A 400 kg, and the GKH65 500 kg.
Q: Can MachForce help me compare aerial platform configurations?
Yes. We can compare working height, outreach, platform capacity, chassis and battery options across the machines in our catalogue and provide a current quote.
