Rock shear box apparatus Mesin Uji Geser Langsung 45-D0548/D

Rock shear box apparatus - Mesin Uji Geser Langsung (Rock Direct Shear test)

Merk : Controls – Italy

Kode Barang : 45-D0548/D

Standard : ASTM D5607

1.1 This test method establishes requirements and laboratory procedures for performing direct shear strength tests on rock specimens. It includes procedures for both intact rock strength and sliding friction tests which can be performed on specimens that are homogeneous, or have planes of weakness, including natural or artificial discontinuities.[ASTM D5607 ]

Fitur Utama Mesin :

• Shear box made in aluminium alloy
• Maximun axial and shear load capacity: 50 kN
• Reversable shear action with 48 mm stroke
• Double version available: analogic and electronic
• Data processing template available as accessory for the digital version
• 2 mould formers included in the testing configuration 

General Description :

This apparatus was originally developed at Imperial college, London, by Professor E. Hoek. It is a simple and practical method of determining the strength and slope stability of rock, both in the field and in the laboratory. The apparatus consists of a shear box designed to accept samples not larger than 115x125 mm, or alternatively cores up to 102 mm dia. The shear box consists of two halves, the upper being connected to two rams for reversible shearing action and the lower connected to a ram for normal load application. The loads are recorded by Bourdon tube load gauges or by pressure transducers (in this case external datalogger is needed).
The normal loading system is complete with an adjustable low friction pressure maintainer to absorb volume changes of the specimen during the shearing action and to ensure a constant vertical stress.
It is conforming to ASTM D5607.

Technical Specifications :

• Max. axial and shear load capacity (for both models): 50 kN
• Manometers range (for both models): 50 kN x 1 kN
• Displacement reading (for Basic model): 5 digital gauges 25x0.001 mm 
• Displacement reading (for Electronic model): 5 potentiometric transducers with 25mm travel 
• Max. sample dimensions: up to dia. 102 mm (for core specimens) and 115 mm x 125 mm (for prism specimens)
• Overall dimensions (loading frame only): 460x250x600 mm
• Weight approx.: 45 kg
