Salient Features of load frame and its accessories

The Load Frame is extremely versatile and designed to conduct Triaxial Unconfined test and Unconfined compression test on rock specimens with diameters from 38mm to 100mm and AX, BX, NX specimens.
The Loading frame consists of a cabinet that houses the gear system and motor with sturdy angle iron frame.
Loading is done through the bottom loading platen, which is carried on a lead screw that advances upwards.
The top load bracket, which slides over two upright pillars, can be positioned at any desired height and locked. It carries a screw adaptor for standard Proving Rings or Load Cells.
Load frame, 200 kn capacity 12 speed from 0.0064 to 1.25 mm per min

FAQs of UNCONFINED COMPRESSION TESTER WITH PROVING RING and DIAL GAUGE:

Q: How does the Unconfined Compression Tester measure rock core strength?

A: The tester measures rock core strength using a manually operated screw mechanism to apply load, a calibrated proving ring to quantify force, and a dial gauge to monitor specimen deformation. The precise load and displacement readings help determine unconfined compressive strength.

Q: What specimen sizes are compatible with this tester?

A: This equipment is compatible with standard core specimens, typically measuring 38 mm in diameter and 76 mm in length. Other sizes can be tested as per industry standards and specific requirements.

Q: When should I use this tester in my laboratory or field work?

A: This tester is ideal whenever you need to assess the unconfined compressive strength of intact rock samples, particularly in geotechnical investigations, site assessments, and academic research projects.

Q: Where is the tester typically used and mounted?

A: The Unconfined Compression Tester is designed for both laboratory and field use. Its table-top mounting and portable construction make it suitable for workbenches and temporary field setups alike.

Q: What is the process for operating the manual compression tester?

A: To operate, mount the specimen between the upper and lower platens, center using adjustable end platens and pins, then apply load using the hand screw. Observe load and deformation increments via the calibrated proving ring and dial gauge until specimen failure.

Q: What are the benefits of using a manual, analog testing device?

A: Manual operation removes the need for electrical supply, ensuring portability and ease of use in remote locations. The robust mechanical components deliver high accuracy (1%) and instantaneous response, making maintenance and troubleshooting straightforward.

Q: How is corrosion prevented given high humidity conditions?

A: The testers structure uses corrosion-resistant painted steel and is recommended for use in environments with humidity up to 90% non-condensing to extend its lifespan. Regular cleaning and proper storage further help avoid corrosion-related damage.
