Proctor/Core Cutter Extruder Frame & Hydraulic Jack

Proctor/Core Cutter Extruder Frame & Hydraulic Jack – Soil Sample Extraction System

The Proctor/Core Cutter Extruder with Hydraulic Jack is a versatile, manual extrusion system designed to remove compacted soil specimens cleanly and efficiently from 100 mm (4 in.) diameter Proctor, CBR, Core Cutter, and Marshall Moulds. With a 20 kN maximum extrusion force, the robust steel frame and hydraulic system offer safe and consistent specimen ejection for geotechnical testing and compaction analysis.

Key Features of Proctor/Core Cutter Extruder Frame & Hydraulic Jack

• Multi-Mould Compatibility: Supplied with adaptor plates to extrude samples from BS Compaction Moulds, 100 mm Proctor, Core Cutter, and Marshall Moulds.

• Manual Hydraulic Jack: Reliable jack mechanism applies up to 20 kN force for controlled, uniform sample extrusion.

• Durable Construction: Heavy-duty steel frame ensures long-term durability and stability during operation.

• Precision Sample Removal: Prevents damage to samples, ensuring accurate downstream testing for bulk density and moisture content.

• User-Friendly Design: Simple operation for both laboratory and field use; requires minimal training.

Applications

• Soil Sample Extraction: Cleanly removes compacted or undisturbed specimens from cylindrical moulds for further analysis.

• Moisture Content Testing: Facilitates moisture determination by allowing easy handling and weighing of soil specimens.

• Bulk Density Determination: Supports sample extraction for in-situ density and compaction tests.

• Quality Control in Construction: Used in geotechnical labs and site investigations to prepare test samples for compaction, CBR, and Marshall testing.
