Post-Tensioned Prestressed Construction

Steel bars in reinforcement are used to place within the tension zone to manage the cracking. Pre-stressed concrete entails the application of forces that tend to bend and compress a concrete structure in counteractive bending that result from loading. The force applied is the tensioning of the steel component in the appearance of wires, bars or high tensile strands. As a typical practice, suppliers calibrate Stressing Equipments to complete post-tension installation successfully.
Types of Stressing Equipments
Multi Strand Jacks are used in stressing all strands in a cable simultaneously. The advantage of this is Hydraulic wrenches high-speed and precise stressing operation of the cables in one trouble-free step.
Staple machines are no ordinary stapling machines. This is used for attaching strands for prestressing concrete. Manually operated staple machines can be used in sites that are isolated sites to where high air pressure systems are not accessible.
Onion Jacks are used to eliminate the use of anchor plates or wedges. It creates anchor point for prestressing cables. The machine forms an onion shape to the end of the cable by means of spreading and separating individual wires.

Hydraulic wrenches range from the most common household types to specialty types.Check out the website that specializes in wrenches at for details.
