POINT LOAD INDEX TESTER:

AS PER IS: 8764, 1978.

Introduction: Used for testing rock, aggregate and core samples as well as out crop specimen in their original shape. Very useful for rock classification. This is a portable instrument and is useful in the field also. Uniaxial compressive strength for rock specimen can also be predicted approximately.

Features:

• Equipment is light and portable
• Rock core specimens can be tested without any preparation
• The instrument can be used in the laboratory as well as at the drilling site
• The results of the test may also be used to predict the uniaxial compressive strength of rock
• With this instrument, a wide range of core sizes can be tested
• The frame has adequate adjustments to align perfectly the loading axis passing through the centre of the bearing plates and loading platens at position of the ram of the hydraulic jack.

General Description and Specifications: The instrument comprises of:-

• Loading Frame: A pillar type load frame on the base of which at the centre is fixed a 10 Ton (100 KN) capacity hydraulic jack with a conical platen at the top of jack.
• Conical platen: is fixed to the top plate of the frame at its centre. The distance between two conical platen is fixed to the top plate of the frame at its centre. The distance between two conical platens is adjustable by vertical movement of the upper plate of the load frame. Loading jack with integral hand operated pump
• Load / Pressure gauge 0-2500 kgf x 25 kgf & 0-10000 kgf x 50 kgf.
