Post Tensioning Jack

Post Tensioning Jack is an equipment that is employed to reinforce concrete and other materials. It is mainly used in construction works like making of bridges, parking structures, slabs, sports stadiums, water tanks, and a lot more. It is a highly efficient machine and performs tensioning and retraction phenomenally. The internal hydraulic fluid control makes it the most reliable machine. Owing to its supreme performance, high build quality, and ruggedness, the tensioning jack is one of the most acclaimed products that we provide. Moreover, we have made available the Post Tensioning Jack in various models and specifications to meet the diverse demands of our clients. 

Post-tensioning is a method of reinforcing (strengthening) concrete or other materials with high-strength steel strands or bars, typically referred to as tendons. Post tensioning applications include office and apartment buildings, parking structures, slabs-on-ground, bridges, sports stadiums, rock and soil anchors, and water-tanks. In many cases, post tensioning allows construction that would otherwise be impossible due to either site constraints or architectural requirements.

Although post tensioning systems require specialized knowledge and expertise to fabricate, assemble and install,the concept is easy to explain. Imagine a series of wooden blocks with holes drilled through them, into which a rubber band is threaded. If one holds the ends of the rubber band, the blocks will sag. Post-tensioning can be demonstrated by placing wing nuts on either end of the rubber band and winding the rubber band so that the blocks are pushed tightly together. If one holds the wing nuts after winding, the blocks will remain straight. The tightened rubber band is comparable to a post-tensioning tendon that has been stretched by hydraulic jacks and is held in place by wedge-type anchoring devices.
