All-Terrain vs Truck-Mounted Cranes — UAE Edition
Why SAC/XCA all-terrains hold value better than QY/STC truck cranes, what 'all-terrain' actually buys you on a UAE jobsite, and when a truck crane is the smarter buy.
The model prefix on a Chinese mobile crane tells you exactly what format it is. QY = truck-mounted (Qi-zhong Yi-dong). STC = same thing in Sany's nomenclature. XCT = a more modern XCMG truck crane line. SAC / XCA = all-terrain. RT / QRY / SRC = rough-terrain. Each format has a different intended job, a different depreciation curve, and a different acceptance pattern at UAE sites.
The three formats in plain language
Truck-mounted (QY / STC / XCT)
A road truck chassis with a crane on top. Drives at highway speeds. Good for jobs where the crane is on tarmac or compacted ground for the whole lift. Cheapest to buy, cheapest to road-tax, easiest to find operators for. Compromised on rough or soft ground because the truck-style steering doesn't crab-walk and ground pressure is high.
All-terrain (SAC / XCA / LTM)
Purpose-built carrier with multiple steering modes (front-only, front+rear, crab, 4-wheel) and big high-flotation tyres. Designed to drive at highway speed AND work on graded but unsealed sites. Heavier and more complex than a truck crane — the carrier has its own engine on bigger units, the cab is taller, and the parts cost is materially higher. Holds value better.
Rough-terrain (RT / QRY / SRC)
Low road speed, four big tyres, two-axle carrier. Lives on site for months at a time. Doesn't drive between jobs on its own — you load it on a low-bed and move it. Excellent on soft ground and tight pad-to-pad work in plant facilities. Niche in the UAE — we sell maybe one in fifteen.
What changes about the buying decision
| Question | Truck-mounted | All-terrain |
|---|---|---|
| Upfront price (same year + capacity) | Baseline | +30–60% |
| 5-year residual | 30–40% | 45–55% |
| Mobilisation cost between jobs | Low (drives itself) | Low (drives itself) |
| Soft ground / matting | Needs full matting plan | Light matting often enough |
| Operator cost | Standard | Modest premium |
| UAE parts | Excellent | Good (longer lead on some hydraulics) |
| Tier-1 site acceptance | Often need newer year | Easier |
Why all-terrain holds value better — in numbers
From our own resale data over five years across about 90 transactions: a 2014–2016 XCMG SAC1600 (160T all-terrain) loses on average about 37% of its first-sale price by year five. A same-year 80T QY80K loses 52%. Both numbers are higher than for new equipment, because most of these units come into the UAE used. But the all-terrain depreciation curve is meaningfully shallower.
Why: bigger projects justify all-terrain rentals at premium day rates, the supply pool is smaller (so a clean used unit has many buyers), and capacity tiers above 130T are mostly all-terrain anyway — so the format and the high-margin work segment are correlated.
When the truck crane is the smarter buy
- You own a fixed yard or factory. If your work is on paved or compacted ground 90% of the time, you're paying the all-terrain premium for a feature you barely use.
- You need 25–80T and your projects are city-centre or industrial. A truck-mounted QY/STC will do everything required.
- Budget is the binding constraint. A clean 2018–2020 truck crane is materially cheaper than an equivalent all-terrain.
- You're entering rental and want maximum unit count. Two truck cranes for the price of one all-terrain may move more revenue.
When all-terrain is worth the premium
- You're working on graded but unsealed sites. Power stations, oil & gas, large precast yards, infrastructure cuttings.
- Your contracts demand 130T+ capacity. Above 130T, all-terrain is essentially the only Chinese-sourced option in the UAE second-hand market — XCMG SAC1600, SAC2000, SAC2200 and XCA220.
- Tier-1 site work. Some EPC clients explicitly require all-terrain formats for crane lifts above 60T, regardless of capacity-rating sufficiency of a truck crane. Read the contract.
- You plan to hold the unit 7+ years. The depreciation gap pays you back over a long hold.
Reading model numbers without a manual
A few rules of thumb that hold for both XCMG and Sany:
- Number after the prefix = capacity in tons. QY50K = 50T truck. SAC1600 = 160T all-terrain.
- Letter suffix usually = generation. QY50K earlier than QY50KA earlier than QY50KB. K-I means revision I (one).
- XCMG XCT series = newer-generation truck cranes with improved cab and electronics, sit between QY and SAC in price.
- XCMG XCA series = compact all-terrain. XCA220 = 220T compact all-terrain.
The format–brand–year stack
Pick in this order: (1) format, driven by the worst-case site you'll work on; (2) capacity, driven by your heaviest expected lift with margin; (3) brand, driven by parts and resale (see XCMG vs Sany); (4) year, driven by site acceptance and budget (see year guide and age limits). Doing it in the other order — picking on a price tag first — is how rental fleets end up with cranes that don't fit the work.
