Digital Compression Testing Machine

Introduction

The digital compression testing machine has been designed to meet the need for a simple, economic and reliable means to test concrete for its compressive strength. The design expressive of simplicity, both of construction and operation, makes the machine easy to use and maintain. The unit is compact, making it useful for site and Laboratory applications. The digital machines are provided with a pace rate controller, to enable maintain a constant of loading.

Features

  • High stability four column load frame
  • Each frame tested for stability and alignment to avoid tension failure during a test and to ensure centre loading
  • Standard Platens for 3 X 6”/ 4 X 8” and 6 X 12” cylinders included.
  • A precise large diameter spherical upper platen for optimum results
  • Variety of optional accessories for cubes, blocks, bricks and flexure test available
  • Motorized hydraulic power pack or pumping unit with rapid approach and automatic overload protection
  • Comes standard with safety Guards on all four sides.

The Complete unit comprises a Loading Unit which is of fully welded or two pillar model construction having a cross-head with a spherical seated platen. The lower platen is attached to the top of the piston. The Loading capacity is of 2000 KN, Cubes up to 200 mm & Cylinders up to 150 mm Dia X 300 mm Height can be tested using the appropriate spacers.

Pumping Unit with choice of compact power pack attached closely to the loading unit or separate hydraulic pumping unit, attached to the loading unit by high pressure hydraulic flexible hose pipe. The pump facilitates rapid approach of the platens for daylight closure and also provides comprehensive control over the application of load. A control valve provides fine control over the loading rate for accurate pacing.

Maximum load is held and retained for approx. 15 min, unless cancelled, using the panel mounted reset switch. Pace rate set for running the test can be maintained manually.
