SDLG RS7220H vs RS8200H: Two 20-Tonne-Class Compactors Compared
Two machines, one weight class, two different answers to the question of how a 20-tonne roller should put its energy into the ground. The SDLG RS7220H and RS8200H both serve Kenya's heavy embankment and road programmes, but they configure their weight, amplitude and drivetrain differently — and those differences decide which one earns its keep on your lift schedule. This comparison discloses the class data honestly, works the pass-count scenarios for both, and shows the soil and programme situations where each machine is the right answer.
Quick answers if you are weighing the two: the SDLG RS7220H vs RS8200H Kenya decision turns on lift thickness, material and programme tempo. RS7220H Kenya buyers typically run high-production road embankments where amplitude and drive configuration favour granular lifts; RS8200H Kenya buyers typically run the heaviest deep-lift schedules where the alternative weight and energy configuration earns its premium. 20 ton roller Kenya planning starts from verified datasheets for both machines — the RS7220H specs and RS8200H specs below are class-level data, with the quotation required to carry the official documents. For soil compactor comparison Kenya purposes the pass-matching arithmetic here is the honest starting point. Both machines are quoted in writing by the SDLG roller dealer Kenya desk on +254 718 686 967; class-adjacent context: the 22-tonne RS8220H sits on the October 2026 price list at KSh 13,000,000 — a related machine, not either of these two.
| RS7220H | ≈22 t-class single-drum soil compactor (per its dedicated guide); high-amplitude configuration for production embankments — datasheet governs |
| RS8200H | 20-tonne-class single-drum compactor; alternative weight, amplitude and drivetrain configuration for heavy deep-lift work — datasheet governs |
| Shared | H-series support, padfoot shell options for cohesive soils, the same dealer backing and warranty terms |
| Guardrail | All figures are configuration-dependent ranges; never mix the two machines' specification sheets |

What the two configurations actually differ on
| Dimension | RS7220H configuration | RS8200H configuration |
|---|---|---|
| Weight class | ≈22 t class per its guide | ≈20 t class per its listing |
| Amplitude/energy | High-amplitude class for granular production lifts | Alternative energy class configured for deep-lift schedules |
| Drivetrain | All-wheel-drive class with crab/steering features per configuration | Configured drivetrain per its datasheet |
| Padfoot option | Yes — cohesive-soil shells | Yes — cohesive-soil shells |
| Natural habitat | Production road embankments, high-tempo programmes | Heaviest deep-lift embankments, dam cores, strict-testing projects |
Pass-count scenarios: where each configuration wins
| Layer scenario | RS7220H configuration | RS8200H configuration |
|---|---|---|
| 300 mm granular subbase, optimum moisture | Production pace; the natural home | Capable; possibly over-configured for the lift |
| 500 mm embankment lift, sandy gravel | Strong; competitive pass counts | Strong; competitive pass counts — trial sections decide |
| 600 mm+ deep lift, mixed fills, strict density gates | Workable; verify by trial | The configuration's natural home; premium converts here |
| Cohesive clay lifts, padfoot shell fitted | Capable, moisture-critical | Capable, moisture-critical — trial sections decide |
Fewer passes per layer saves fuel, water-cart support, operator hours and retest risk; the compounding across a kilometre of embankment is the real business case for choosing correctly. Trial sections remain the authority — the table orients the decision, the site verifies it.
When the RS7220H is the right machine
- Your programme is production-graded road embankment work at high tempo
- Lifts sit in the 300–500 mm band on granular materials
- You value the heavier-class configuration's pace on balanced lifts
- Your support fleet — water cart, testing schedule — is sized for production cycling
The RS7220H heavy-embankment guide covers that machine's own case.
When the RS8200H earns its premium
- Your lift schedule genuinely runs deep — 500 mm and above on a regular basis
- Testing regimes are strict and failed-layer costs dominate the economics
- Material mixes reward the alternative energy configuration's depth behaviour
- The programme is long enough that the premium compounds into passes saved
The RS8200H guide covers that machine's own case; this comparison exists so the choice between them is made before either quotation is requested.
The ownership-economics angle
Both machines share the RS line's operating disciplines — vibration management, scraper and water-system care, scheduled service — and the padfoot option that opens cohesive-soil work. The step between them prices in purchase, transport, fuel and tyres, and returns passes saved on deep lifts. The honest test is the same as every class decision in this campaign: what fraction of your annual layer schedule genuinely sits in the deep-lift band, and what is a failed-layer retest worth on your programme? Model both in the cost estimate calculator with your real numbers.
A season with each machine: two realistic programmes
| Programme element | RS7220H season | RS8200H season |
|---|---|---|
| Programme type | County highway embankment, 40 km, granular fills | Dam and access-road programme, deep mixed fills |
| Lift schedule | 300–500 mm lifts at production tempo | 500–600 mm lifts with strict field-density gates |
| Testing regime | Standard verification, steady rhythm | Layer-by-layer verification; failed-layer costs dominate |
| Daily pattern | High pass counts absorbed by tempo; water cart and tester keep pace | Fewer passes per lift; moisture conditioning critical |
| End-of-season position | Kilometres completed on schedule; wear parts as planned | Deep lifts certified; retest risk avoided |
Neither season is a caricature; both describe working Kenyan programmes. The RS7220H's season monetises tempo and breadth — many kilometres, balanced lifts, steady testing — while the RS8200H's monetises depth and certainty, where a failed layer costs more than any rolling premium. The discipline is identical at both: match the machine to the lift schedule that actually exists, and let trial sections rather than brochures settle borderline cases.
Aligning the roller, the water cart and the tester
Whichever machine wins the comparison, one discipline decides real-world performance: the roller, the water cart and the testing schedule must work as one system. Moisture outside optimum turns the heaviest roller into an expensive smoothing iron; density checks that arrive after a failed layer cost more than checks that guide the next pass. Align the three so field results inform the same day's moisture conditioning and pass planning — on tested projects this feedback loop saves more money than any machine-level decision, and it is entirely within your control from the first lift.
Operating costs across both configurations
The shared cost lines dominate either machine. Vibration-system discipline: vibration only on the mat, never stationary or on rigid surfaces — the bearing-protection rule is absolute on both configurations. Scrapers and water systems: a clean drum compacts, a clogged one polishes; daily scraper adjustment and reliable spray bars cut defect rates on both machines. Scheduled service: modest if honoured, with dusty embankment air punishing skipped filters faster than any other negligence. Transport: both machines move at similar cost; batching mobilisation by corridor converts logistics into planning. Budget these four at purchase and neither machine surprises you at month six.
For buyers ready to buy compactor Kenya stock at the heavy classes, the purchase conversation carries the same datasheet discipline as every campaign article — and the compactor for sale Kenya market rewards documented machines: a roller with its service file, PDI records and trial-section history outsells an identical hours-only unit measurably, because serious embankment buyers read files before they phone.
The trial-section discipline
One practice separates contractors who never fight their compactors from those who do: the trial section. Before production rolling begins, compact a short demonstration strip at the intended lift thickness, moisture and pass count — then test it. The trial answers the question no brochure can: how does this material, at this moisture, respond to this machine's energy? Adjust the pass plan from the result, document the parameters, and the production schedule inherits a verified baseline rather than a guess. The dealer supports trial-section planning as part of the commissioning conversation; ask for the worksheet when you request the quotation — it is the single document that turns a compactor purchase into a compactor programme, and it costs nothing but the discipline to run it before the first production lift — the cheapest insurance either machine carries on any embankment programme.
Frequently asked questions
1. What is the difference between the RS7220H and RS8200H?
Both are single-drum soil compactors in the 20–22-tonne band, but they configure weight, amplitude and drivetrain differently for different lift schedules. The official datasheets state the exact figures for each quoted unit — never mix the two documents.
2. Which is better for deep-lift embankments?
The RS8200H's configuration targets the heaviest deep-lift schedules; the RS7220H targets production embankments at tempo. Trial sections on your material decide the honest answer for your site.
3. Can both machines run padfoot shells?
Yes — both offer padfoot options for cohesive soils, subject to fitment verification and weight recalculation in writing.
4. Is the RS8200H the same as the RS8220H on the price list?
No — the RS8220H is a 22-tonne machine listed at KSh 13,000,000 on the October 2026 price list; it is class-adjacent context only and neither machine's price. Written quotations for the RS7220H and RS8200H carry their own verified configurations.
5. Which is cheaper to run per hour?
Per hour, the two are close; per tonne compacted on their matched lifts, the correctly chosen machine wins materially. Match the machine to the lift schedule and the economics resolve themselves.
6. Can I finance either machine on the same structure?
Yes — both follow standard asset finance with deposits and tenors scaled to the loan. The documents checklist covers the file.
7. What if my programme spans both lift bands?
Mixed schedules favour one machine with disciplined lift planning, or the pairing conversation with the SDLG desk — two compactors on one programme is common on dam and highway jobs.
8. Where do I start the comparison for my programme?
Send the desk your lift schedule, materials and testing regime — the team will run both machines' pass-matching worksheets and quote whichever wins with the datasheets attached.
