It has become recognized that is testing laboratory the best performance can only be obtained if all the springs of a uniform type possess the same mechanical properties. Special testing machines for dealing with tension and compression springs of helical pattern are to be made use of the machines of very simple designs used for statical tests on springs cannot be used for compression and tensile tests. Spring testing machine is an earnest effort in this direction. Machines enable load deflection tests of tension and compression springs to be carried out accurately and quickly.
The cabinet contains the hydraulic unit the hand wheel of the pump and the release valve handle are outside the cabinet for easy operation. This compact base carrier two fixed upright and four horizontal plates. The first and the third plates with two small uprights from an adjustable frame. The second and the fourth plates are fixed. A square threaded wheel arrangements provided for adjusting the height of the springs.
A bourdon type gauge is fixed for direct load measurements. One fixed upright is graduated to denote the deflections or tension of the springs for direct readings. A thimble with on arrow mark is provided to facilitate the readings. The machine is capable of accommodating 8" length 1/2" dial. Rod up to 4" dia. Springs for tension, 6" length 1/2" dia. Rod, 4" springs for compression. Scale
