AZA 0909 LOAD FRAME, MOTORISED, 30 SPEEDS

Description

The Load Frame, Motorised, 30 Speeds is an advanced and versatile soil testing machine designed to apply controlled vertical loads for various geotechnical tests. Whether you’re performing California Bearing Ratio (CBR), Unconfined Compressive Strength (UCS), triaxial shear, or consolidation tests, this load frame delivers consistent performance with precision and efficiency.

With its 30-speed gearbox and motorised drive system, the frame enables fine-tuned adjustment of loading rates, supporting both slow consolidation tests and high-rate CBR tests. It offers unmatched control over displacement rates, ensuring full compliance with national and international test standards.

Applications

This motorised load frame is used extensively in laboratories for:

• California Bearing Ratio (CBR) testing

• Triaxial compression tests (UU, CU, CD)

• Unconfined compressive strength (UCS) of soil

• One-dimensional consolidation (Oedometer) testing

• Soil and rock mechanical behavior studies

Its digital or analog loading interface and adjustable speed selection make it ideal for academic institutions, geotechnical labs, and civil engineering test centers.

Construction & Features

Built on a rigid steel structure, the frame minimizes deflection and vibration during operation. The gearbox-integrated motor drive ensures smooth and progressive application of load, avoiding jerks or uneven pressures. Features include:

• 30 selectable speeds, ranging from 0.05 mm/min to 60 mm/min

• Reversible drive to reset piston position quickly

• Digital displacement control with optional load cells

• Fixture compatibility with standard test accessories (CBR moulds, triaxial cells, UCS platens)

• Overload protection and emergency stop for operator safety

Compliance and Standards

This machine complies with major geotechnical testing standards, including:

• ASTM D1883 – CBR Testing
