Motorised CBR Machine
Product Code : LSK-SM-10662
Motorised CBR Machine (SKU LSK-SM-10662) is a twin column load frame with a motorised drive for the California Bearing Ratio (CBR) test, which rates the bearing capacity of subgrade and base soils for road and pavement design. Civil engineering colleges, polytechnics and highway training labs use it. Institutes, tender contractors and distributors can source the machine from Science Lab Supplies, whose quotations are issued from Ambala, India.
Specifications
Every figure given for the 50 kN CBR frame appears as its own row below. In short, the twin column frame offers 800 mm vertical and 255 mm horizontal clearance, and its 133 mm platen travels 105 mm under a motorised drive with two selectable load speeds, listed as 1.27 mm and 1.0 mm.

Applications and Experiments for the Motorised CBR Machine
The machine pushes a plunger into a compacted or soaked soil specimen at a steady rate while the load for set penetrations is recorded. Compared with a standard crushed stone, that load gives the CBR value used to size pavement layers in highway engineering.
- B.Tech / B.E. civil and transportation engineering: laboratory CBR of subgrade soils, soaked and unsoaked, on specimens prepared with the Automatic Mechanical Soil Compactor.
- Diploma civil engineering: highway materials practicals on soils and granular bases.
- TVET road construction modules: checking fill and subgrade materials, and comparing laboratory values with in-situ results from the Field CBR Equipment.
Standard Scope of Supply
The machine is supplied as the twin column frame with its motorised drive, 50 kN capacity and 133 mm platen. CBR moulds, a penetration piston, a load measuring device and dial gauges can be requested on the same quotation, which names every item included in the offer.
Packing, MOQ and Lead Time
We quote anything from one machine to a full highway materials lab, and every quotation shows the packing, delivery time and price for the quantity asked. Moulds and a compactor can be priced alongside, so vocational training equipment for road courses can be sourced in one order.
Science Lab Supplies is a registered exporter with an Importer-Exporter Code and can ship to buyers in South Africa, Qatar, Sri Lanka, Vietnam, Malaysia and Peru. Technical points about speeds or clearances can be put to the team on the contact page, the frame can be listed in the enquiry cart, and tender documents go through the lab tender page.
Frequently Asked Questions
What does a CBR machine measure?
It measures the load needed to push a plunger into a soil specimen at a set rate. The load at standard penetrations, as a percentage of a reference material, is the California Bearing Ratio used in pavement design.
How does it differ from a hand-operated CBR machine?
The motorised drive keeps the penetration rate steady without manual winding. This frame offers 50 kN and two selectable speeds, while the hand-operated machine in the same range uses a 5000 kg manual frame with high and low rates of travel.
Who supplies the Motorised CBR Machine?
Science Lab Supplies supplies this CBR frame from Ambala, India. Engineering colleges, polytechnics, TVET centres and contractors deal directly with its team, and the quotation confirms the drive, speeds and any accessories included.
Can it be quoted for a tender?
Yes. Share the tender specification, quantity and delivery location, and the quotation will respond item by item, including any moulds or accessories the tender asks for.
