SDLG RD730 vs RD7100 vs RD7120: Tandem Roller Selection Guide
Three machines, one ladder: the RD730, RD7100 and RD7120 span Kenyan asphalt work from estate patches to highway carriageways. Choosing between them is not about which is "best" — it is about which class your programme actually sustains. A roller undersized for its work polishes instead of compacting and fails density checks; oversized, it burns fuel and logistics on capability it never uses. This guide maps the full ladder with the confirmed price anchor where one exists, the application bands for each class, and the selection logic that places your programme on the right rung.
Quick answers if you are choosing a tandem: the SDLG RD730 vs RD7100 vs RD7120 Kenya ladder runs from light to heavy: the RD730 Kenya — now confirmed as a 3-tonne light tandem at KSh 4,500,000 inclusive on the October 2026 dealer price list (indicative, subject to change) — serves footpaths, patches and estates; the RD7100 Kenya class serves municipal roads, surface dressing and mid-size paving support; the RD7120 Kenya class serves highways and heavy paving trains. Tandem roller selection Kenya starts from your layer schedule: thin seals and small patches point down the ladder; full-width wearing courses and paving-train support point up it. The RD730 price Kenya buyers can anchor is the KSh 4.5M list figure; RD7100 price Kenya and RD7120 price Kenya are written quotations against verified datasheets. For compactor selection Kenya buyers ready to buy tandem roller Kenya stock through the authorized channel, the desk on +254 718 686 967 places programmes on this ladder honestly and quotes the chosen class with its datasheet attached.
| RD730 | 3 t light tandem (confirmed by Oct 2026 price list at KSh 4,500,000 incl., indicative) — patches, footpaths, estates |
| RD7100 | 10 t class — municipal roads, surface dressing, paving support |
| RD7120 | 12 t class — highways, heavy paving trains, full-width finishing |

The ladder at a glance
| Class | Applications | Typical buyer | Guide |
|---|---|---|---|
| RD730 (3 t) | Footpaths, pothole patches, estate roads, trench reinstatement | County maintenance units, small contractors, plant hire | Confirmed price on list |
| RD7100 (10 t) | Municipal asphalt finishing, surface dressing, mid-size paving support | Road contractors, municipal fleets | Datasheet-verified quote |
| RD7120 (12 t) | Highway wearing courses, heavy paving trains, full-width finishing | Highway and paving contractors | Datasheet-verified quote |
The pattern across the ladder is workload matching: each class earns its premium only where the programme genuinely sustains it. Buyers whose work spans two bands should say so to the desk — pairing advice is cheaper than the wrong single purchase.
Choosing by layer schedule
| Your programme | Points to |
|---|---|
| Trench reinstatement, pothole patches, estate access | RD730 — light, trailer-friendly, confirmed at KSh 4.5M incl. |
| Municipal roads, urban repairs, mid-size surface dressing | RD7100 — the class's natural home |
| Highway wearing courses, full-width seals, paving-train support | RD7120 — production pace the class exists for |
| Programme spans two bands | Run the pair conversation with the SDLG desk |
Borderline cases settle by trial section, not by table: compact a demonstration strip at the intended thickness and test it, then adjust the class or the pass plan from the result. The worksheet is available from the desk with either quotation.
Pass-count reality across the ladder
Illustrative planning figures with stated assumptions (your mix design and trial section remain the authority):
| Layer scenario | RD730 class | RD7100 class | RD7120 class |
|---|---|---|---|
| 25 mm surface dressing finish | Capable at slow pace | Production pace | Production pace with reserve |
| 50 mm wearing course | Under-class; polish risk | Breakdown and finish window | Production window |
| 75 mm+ base layers | Not suitable | Stretch; verify by trial | Coordinated breakdown role |
Fewer passes per layer saves fuel, water, operator hours and retest risk; the compounding across a programme season is the real business case for choosing the right rung rather than the nearest one.
Operating-cost notes across the classes
The disciplines are shared; the budgets scale. Water systems and scrapers decide surface quality at every class — clean bars and full tanks are production equipment, not accessories. Vibration management protects drum bearings at every weight — never on rigid surfaces, never stationary. Tyre and drum wear lines scale with class, and the 12-tonne class meets them sooner. Transport runs from cheap and frequent (RD730) to planned and corridor-based (RD7120). Budget these four at purchase and no class surprises you at month six.
Hire versus ownership on the ladder
Hire suits single short programmes at any rung; ownership pulls ahead at sustained utilisation, and the pull-ahead point arrives earliest at the light end (the RD730's low fixed costs) and latest at the heavy end (the RD7120's programme-length placements). Contractors building county relationships across seasons typically find the 10-tonne class the natural first ownership rung, with the light class added as utilisation proves out — the desk will run your actual pattern through the calculator rather than a national average.
Three buyer profiles, three answers
| Profile | Ladder position | Reasoning |
|---|---|---|
| County maintenance unit, patches and estate work | RD730 | Confirmed KSh 4.5M entry point; trailer-friendly; the work never exceeds its class |
| Growing road contractor, municipal-dominant pipeline | RD7100 | The natural first ownership rung; hires the extremes as programmes demand |
| Highway and paving specialist, kilometre programmes | RD7120 | Production pace the class exists for; placements long enough to amortise |
Profiles overlap, and the desk sees every hybrid: the county unit that wins a highway contract, the municipal contractor crossing into sealing. The ladder does not change with the profile — only the rung does. When the programme moves, the hire-versus-own analysis moves with it, and the calculator conversation is free.
Transport and logistics across the ladder
Transport behaviour differs enough across the classes to belong in the selection arithmetic. The RD730 moves frequently and cheaply — that is part of its design value, and single-operator trailers keep mobilisation costs low across scattered patch work. The RD7100 moves at moderate cost and benefits from batching by district. The RD7120 moves as a planned event: corridor batching, route surveys and season-long placements are its natural habitat, and ad-hoc weekly moves quietly consume the margin the class exists to earn. Contractors whose programmes scatter geographically should weigh the light class's logistics advantage honestly before stepping up.
Resale and fleet-sequencing notes
Tandem rollers resell on documented history as the rest of the range does, and the ladder rewards a sequencing discipline: buy the class your pipeline sustains, keep the file complete, and let the trade-in conversation start from the machine's documented programme rather than its hours. Fleets that step up the ladder over years typically fund each step from the last machine's documented exit value — the file is the currency at every rung.
The pairing conversation: when one class is not enough
Programmes that genuinely span the ladder deserve the pairing conversation rather than a compromise machine. The common Kenyan pattern: hold the 10-tonne class as the ownership anchor, hire the RD730 for patch-heavy seasons, and hire the RD7120 for highway windows. The economics usually beat owning two classes outright, because the extremes' utilisation is seasonal while the middle rung earns all year. The desk runs the three-way utilisation model against your pipeline; the answer is arithmetic, not instinct — and it changes as the pipeline grows, so revisit it annually rather than at crisis points. Owners who schedule that review find the ladder works for them; owners who skip it usually discover the mismatch at the worst moment of the season — typically the week the highway contract starts and the patch fleet is still on the books at full finance cost every idle month.
What the ladder means for finance structures
The three classes also finance differently in practice. The RD730's confirmed price and low fixed costs make it the most accessible financed machine on the ladder — small deposits, short tenors, quick payoffs. The RD7100 follows the standard asset structure. The RD7120's programme-length placements argue for seasonal repayment profiles matched to the earning calendar, negotiated before signing. The finance conversation should ride the same ladder as the machine selection, and the desk structures both in one file.
Frequently asked questions
1. What does the RD730 cost in Kenya?
The dealer price list effective October 2026 shows KSh 4,500,000 inclusive as a 3-tonne light tandem — indicative and subject to change; a written quotation confirms the current figure within 24 hours of inquiry.
2. Which tandem do I need for chipseal work?
The kneading pass belongs to the pneumatic RP6300; the tandels seat the chip beforehand. On layer thickness alone, municipal chipseal points to the RD7100 class and full-width highway seals to the RD7120 — read the RP6300 guide for the sealing train.
3. RD7100 or RD7120 for a growing road contractor?
Current municipal-dominant programmes point to the RD7100; committed highway pipelines point to the RD7120. If the pipeline is moving upward within two years, buying the heavier class once usually beats trading up later.
4. Can the RD730 handle asphalt at all?
Thin seals and small patches, yes — that is its design purpose. Wearing courses beyond 25 mm exceed its class and risk polishing instead of compacting.
5. Do I need all three classes?
Rarely. Most contractors own one class and hire the others as programmes demand; fleets that genuinely span the ladder typically hold the 10-tonne class and hire the extremes.
6. Can I finance a tandem roller purchase?
Yes — asset finance applies at every class, with the RD730's confirmed list price anchoring the light end. The documents checklist covers the file.
7. What warranty comes with a new tandem?
One year or 2,000 hours standard factory cover at every class, honoured in Kenya and extendable to two years per the dealer's packages — issued in writing with the delivery documents.
8. Where do I start the selection conversation?
Send the desk your layer schedule, programme types and counties — the team will place you on the ladder, run the trial-section worksheet and quote the right class with the datasheet attached.
