Triaxial Test Apparatus

Section Description
Loading Frame Features
  • Two pillar type construction.
  • Enclosed motor and gear system.
  • Jewel lamps indicating direction of motion.
  • Simple and easy operation.
Universal Triaxial Cell Stationary bushing type triaxial cell suitable for testing specimens of 38 mm diameter × 76 mm long.

The triaxial cell consists of a Perspex chamber fitted with an anvil and loading plunger.
The chamber can be easily opened by releasing four tie rods and is leak-proof up to 10 bar pressure (10 kg/cm²).
Triaxial Electronic Conversion Kit Used for maintaining constant lateral pressure on triaxial test specimens throughout the testing period.

The system is provided with two air-water interface chambers having individual pressure regulators for accurate outlet pressure control at desired pressure levels.

Suitable air compressor should be supplied separately with the apparatus.
Measurement System
  • Direct reading of strain, load, and pore pressure.
  • External Load Cell – 10 kN capacity.
  • Pore Pressure Transducer – 20 bar (20 kg/cm²) capacity.
  • LVDT (Displacement Sensor) with 0–20 mm measuring range.
Power Supply Suitable for operation on 220 V, 50 Hz, Single Phase AC supply.

Description

Section Description
Loading Frame The Motorized Loading Frame (50 kN capacity) is highly versatile and specially designed for conducting triaxial shear tests on soil and rock specimens.

The unit consists of a sturdy cabinet housing the motor and gear system mounted on a heavy-duty angle iron frame.
Loading is applied through the bottom loading platen carried on a lead screw arrangement moving upward.

The top load bracket slides over two upright pillars and can be adjusted to any required height and securely locked in position.
The bracket is fitted with a screw adaptor suitable for standard proving rings or load cells.

The loading section is detachable from the main unit for convenient transportation and protection of tension rods from damage.
Rates of Strain 6 fixed strain speeds provided for accurate testing operations.
Power Supply Suitable for operation on 220 V, 50 Hz, Single Phase AC supply.
