<p>The invention relates to providing a solution with a combination of hydraulic lifting and mechanical holding mechanism, wherein the invention specifically provides a combination of a jacking mechanism and a holding mechanism whereby the load is lifted hydraulically and retrogression of the hydraulic piston is obviated by mechanical means. The system comprises of a loading frame with four column and platens one at top and another at bottom and lockable in the threaded portion of the frame by locknuts. The system is associated operably a feed back control means to maintain continuously a constant sensed force on the specimen placed for test.</p> |
