SDLG RS7120H Soil Compactor Kenya: Specs, Price and Availability

Published 2026-10-25 · Equipment, Technology & Fleet Management · Reviewed by the SDLG Product Desk, Trust Partners Geo-Group Ltd

The SDLG RS7120H is a soil compactor — a heavy single-drum vibratory roller that compresses soil, gravel and road-base material in layers until it reaches the density the engineer specifies. It is the 12-tonne-class machine in the SDLG compaction line sold in Kenya by Trust Partners Geo-Group Ltd, sitting between the lighter compactors and the heavy embankment rollers. If your project has a compaction specification — a road subgrade, a dam lift, a building platform — this is the class of machine that meets it. This guide sets out the RS7120H's verified specification status, how pricing works in Kenya, the smooth-drum and padfoot decision, and the applications where this class earns its keep.

SDLG RS7120H Specifications: Verified Status

The Trust Partners range listing places the RS7120H in the 12-tonne soil compactor class. Exact operating weight, engine output, amplitude, centrifugal force and drum dimensions are published on your quotation from the official configuration-specific datasheet and stock-unit nameplate — not averaged from brochures. Until that datasheet is in hand, the table below states what is confirmed and what is pending.

Verification date on quotation: the SDLG desk records the datasheet revision and stock-unit nameplate against every RS7120H quote. If you are comparing the RS7120H against a competing compactor, ask us for the datasheet and we will send the exact configuration sheet.

Price and Availability in Kenya

We do not publish a headline price for the RS7120H because a responsible compactor price depends on the exact machine: configuration, drum type and any padfoot fitment, delivery county, and the current import and exchange-rate position at the time of quotation. What we can state plainly is how the quotation is built, so you can compare like-for-like:

• Machine and configuration — the base unit as per the verified datasheet, quoted per unit.
• Drum options — smooth drum as standard; padfoot shells and any amplitude options quoted separately.
• Delivery — Ruai yard collection or delivered to your county, quoted by destination.
• Commissioning and operator familiarization — included; confirm scope on the quote.
• Warranty — SDLG warranty terms as supplied by the dealer, stated in writing on the quotation.
• Financing — dealer-introduced asset finance; approval and terms rest with the lender. See our SDLG financing hub and use the cost-estimate calculator for a project budget figure.

Any price figure discussed verbally or by message is indicative only and is not a firm offer. Product and Offer structured data is applied on this site only where a genuine, visible sale offer with matching price, condition and stock exists; this guide is a specification and selection resource, not a live offer.

Applications: Where the RS7120H Earns Its Keep

1. Road subgrade and base compaction

The core workload: compacting subgrade and graded crushed layers to the density specified in the road design, ahead of the surface course. The method — lift thickness, moisture and pass count — is set by the specification and proven by testing, which our earthworks QA and compaction testing guide and proctor and field-density testing guide explain.

2. Embankments and dam lifts

Farm roads, causeways and dam embankments are built in compacted lifts; the compactor works in sequence with the excavation and hauling fleet. Our dam and water pan earthworks cost guide shows how compaction fits the programme.

3. Building platforms and hardstandings

Structures start with a certified platform. The RS7120H compacts platform fill to the engineered density before foundations are cast — the same discipline set out in our subgrade preparation and quality-control guide.

4. Trench backfill

Water, sewer and fibre trenches are backfilled in layers and compacted to protect the installed line and restore the surface. Our trench backfilling and compaction standards guide covers layer thickness and the failures that testing catches.

5. Farm roads, feedlots and yards

Ranches, dairies and feedlots compact access roads, loafing pads and yard areas where mud and dust are production problems, not just maintenance ones. Compacted, well-shaped surfaces drain faster, hold up under feed trucks and cut the vet bills that come with standing water. Our asphalt versus murram guide helps decide the surface, and the road maintenance guide covers the grading cycle that keeps farm roads usable between compaction passes.

Smooth Drum or Padfoot?

Drum choice follows the soil. Smooth drums suit granular material — sands, gravels and crushed stone — where kneading is not required. Padfoot (sheepsfoot) shells act on cohesive soils — clays and silts — where the feet knead material from the inside of the lift outward. Many Kenyan projects mix both, so the RS7120H's padfoot option is quoted as a configuration rather than an afterthought. Our vibratory versus static roller guide explains the selection logic by soil type.

The Compaction Method Matters More Than the Machine Badge

A compactor does not guarantee compliance; the method does. Lift thickness, moisture within the specified range, pass count and field-density testing decide whether the layer passes &mdash and roller passes alone prove nothing. The RS7120H is specified against the project's target density, and the dealer can advise on method, but the verification is the engineer's test regime. For the hire-and-ownership economics around compaction fleets, see our vibratory roller hire pricing guide, the hire cost calculation guide and current hire pricing. Moisture conditioning typically pairs the compactor with a water bowser, covered in our water bowser hire guide.

Ownership, Service and Support

Buying through an authorized dealer matters most after the invoice. Trust Partners Geo-Group supports RS7120H owners with genuine SDLG filters, drum scrapers, bearing and vibration-system parts through the Ruai workshop, technician call-out for county fleets, operator familiarization at handover, and warranty administration documented in writing. Daily care is deliberately simple — scraper adjustment, drum and bearing checks, fluid and filter inspections — and the handover pack states the service intervals from the official manual for your unit's configuration. For crews weighing a compactor purchase against hiring per project, the SDLG vs CAT and Komatsu comparison hub explains how we build evidence-based brand comparisons, and the backhoe, dozer and compact equipment range covers the utility machines smaller contractors pair with a hired compactor.

Delivery is quoted to county level, and commissioning includes a walk-through of the vibration controls, scraper settings and daily checklist with your operator before the machine starts its first lift. If your programme spans multiple counties, the desk can sequence delivery with your works calendar so the compactor arrives when the layers are ready — not before.

RS7120H vs Other Compaction Machines

Single-drum soil compactors work soil and base layers; tandem rollers finish asphalt; compactors below this class suit footpaths and small works. If your programme is surfacing rather than earthworks, the SDLG compaction roller range page and our single-drum versus tandem roller guide map the split. The wider fleet context — SDLG equipment, excavators, wheel loaders and motor graders — covers the machines the compactor works alongside on road and dam jobs.
