Mechanical Creep and Rupture Testing Machine

  • GB/T2039, GB/T 10120, EN ISO 204 and ASTM E139 etc

    • Free standing load frame features a small footprint that optimizes laboratory floor space, with shock absorbing and vibration isolation. 

    • Specimen rupture switch senses when the specimen fails and stops the timer

    • Compact load frame with one lever arm with a load accuracy of less than ±0.5% 

    • Hardened knife edges and V-blocks for long life fulcrum point

    • Over travel limit switch assembly

    • The draw head is designed to automatically adjust during a test to compensate for specimen elongation and keep level horizontal.

    • This adjustment keeps the lever arm level and provides an accurate lever arm ratio. This process provides an accurate and constant load on the specimen.

    • Interface can be connected to computer and the testing graph of Strain-stress, temperature display and data can be displayed and processed by computer.

    • Standards: GB/T2039, GB/T 20120, EN ISO 204 and ASTM E139, ISO 7500-1etc.

    • The loading frame is with four columns and single-lever beam with free standing feature. The loading system of the testing machine is lever and weight loading. Grade 1 lever: the lever ratio is 50:1 (optional is 20:1), load accuracy is within 0.5%.

    • Fulcrum material is high strength tool steel, heat treated to 50-55HRC.

    • The material for frame is IS226 mild steel (MS).

    • Spirit level is mounted to indicate beam position.

    • There are two modes for unloading, one is manual, and the other is motorized.

    • Lever horizontality-adjusting system control: optical fibre sensor adopted for upper & lower main generation signal source.

    • Manual unloading mechanism: it can be adjusted manually when power failure happened suddenly, which can effectively protect the machine and specimen during test.

    • Free standing load frame with small footprint optimizes floor space and no special foundation.
