CBR Test Machine Hand Operated
Product Code : LSK-SM-10649
CBR Test Machine Hand Operated (SKU LSK-SM-10649) is a laboratory set for the California Bearing Ratio test, in which a 50 mm piston is pressed into soil compacted in a 150 mm mould and the load for set penetrations is recorded. Soil mechanics and highway engineering labs in engineering colleges, polytechnics and TVET institutes use it. Science Lab Supplies offers it from Ambala, India to colleges, training centres, tender contractors and distributors.
Specifications
A hand-operated load frame of 5000 kg capacity, with high and low rates of travel on the load screw, drives the penetration piston. Mould and plates are gun-metal or brass, and the set includes the spacer disc, surcharge weights, swell plate and rammers needed to prepare and test specimens.

Applications and Experiments for the CBR Test Machine
The machine measures the CBR value of subgrade, sub-base and base materials compacted in the laboratory, the figure used to design flexible pavement thickness. Specimens can be tested unsoaked or after soaking, with swell read on the tripod, in degree, diploma and TVET highway engineering practicals.
- B.E./B.Tech civil engineering: laboratory CBR test for pavement design.
- Diploma civil engineering: compacting soil in the CBR mould and penetration testing.
- TVET road construction modules: testing subgrade soil and granular materials.
Standard Scope of Supply
One of each listed item: load frame, mould with base plate and collar, spacer disc, piston, annular and slotted weights, perforated swell plate with tripod, cutting collar and rammers. The set is supplied without proving ring and dial gauge, which are chosen separately and can be quoted with it.
Packing, MOQ and Lead Time
Ask for a quotation for one machine or for several for a highway lab or vocational training centre; the quotation gives packing, delivery time and price for your quantity. A proving ring and dial gauges can be added to it.

Frequently Asked Questions
Are the proving ring and dial gauge included?
No. The machine is supplied without proving ring and dial gauge, so they can be matched to the loads in your tests and added to the same quotation.
What mould size does it use?
A gun-metal or brass mould of 150 mm internal diameter and 175 mm height, with a perforated base plate, a 50 mm extension collar and a 148 mm spacer disc.
How is swelling measured?
During soaking, the perforated plate with adjustable stem rests on the specimen and a dial gauge held on the metal tripod records its rise. The dial gauge is ordered separately.
Who supplies the CBR Test Machine Hand Operated?
Science Lab Supplies supplies it from Ambala, India, and its quotation lists every part above.
