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. Science Lab Supplies offers the machine from Ambala, India to institutes, tender contractors and distributors.
Specifications
The frame has a 50 kN capacity with 800 mm maximum vertical clearance and 255 mm horizontal clearance. Its 133 mm diameter platen travels up to 105 mm, driven by the motor at one of 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.
- Diploma civil engineering: highway materials practicals on soils and granular bases.
- TVET road construction modules: checking fill and subgrade materials before construction.
Standard Scope of Supply
The listing describes the twin column frame with its motorised drive, 50 kN capacity and 133 mm platen. It does not list CBR moulds, a penetration piston, a load measuring device or dial gauges, so request these on the same quotation, which will name every item included.
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. Reach the team on the contact page, build a list in the enquiry cart, or open the lab tender page for tender work.
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, so readings are more consistent between operators. This frame offers 50 kN capacity and two selectable speeds.
Who supplies the Motorised CBR Machine?
The machine comes from Science Lab Supplies in Ambala, India, which quotes it to engineering colleges, polytechnics, TVET centres and contractors.
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.
Related CBR and Pavement Soil Testing Equipment
A CBR result depends on how the specimen was compacted and how the field soil compares, so these four Soil Mechanics items are often ordered with the machine. They cover specimen preparation, a manual alternative and in-situ bearing tests on site.
- Automatic Mechanical Soil Compactor — compacts specimens in 152 mm moulds.
- CBR Test Machine Hand Operated — manual frame for smaller labs.
- Field CBR Equipment — in-situ CBR tests on site.
- Plate Bearing Test — field bearing capacity of prepared ground.
