Double-Action System. The 5DA1, 5DA1-AL, and 6DA1 jacks are double-acting, meaning that the jacks open and retract using hydraulic power. Both jacks use power wedge setters to seat the wedges into the anchor. After the desired stressing pressure is achieved, the valve on the pump is switched to the retract position.
In the case of some mono anchorage system, the Wedge will hold an individual tensile element directly to the Bearing Plate. ... Prestressed Concrete, Prestressing, Slab Anchorage, Stressing Equipment, Stressing Jack. TMG PC Strand Manufacturing Facilities. ... E-Force Engineering Pte Ltd, ...
Post tensioning was carried out for the prestressed concrete structure. Flat Anchors of 3 - 5 x 12.70mm PC strand were used for the slab post tensioning, and multistrand Anchors of 19 x 12.70mm PC strand were used for the beam post tensioning. Both Mono Jack and 300 ton Stressing Jack were used in this project.
TMG Stressing Jack (also known as Multi Strand Jack) is small, compact and highly efficient. Unlike the Mono Jack where a single PC strand is stressed at any one time, Stressing Jack is meant to stress all the strands in the tendon at the same time. The purpose of stressing all strands at the same time is for speed and accuracy.
Mono Strand Prestressing Jacks. PJM Industrial offer 10T, 25T and 30T Mono Strand Prestressing Jacks or Pre Stressing Jacks. 10 Tonne Mono Strand Pre-stressing Jack. The 10 Tonne Mono Strand Prestressing Jack is ideal for initialing in the concrete pre-stressing industry and Roof Bolting in the Mining Industry.
Usage: For pre-stressing single strand or flat anchor system 4. Applications: bridges, high buildings, coal mine , railway and subway, water conservancy and hydropower engineering .
About 58% of these are car jacks, 17% are metal building materials. A wide variety of prestressing jack options are available to you, such as hydraulic jack, electric jack, and bottle jack. You can also choose from >50t, 21-30t, and 1-10t. As well as from free samples, paid samples. There are 3,784 prestressing jack suppliers, mainly located in Asia.

THE FREYSSINET PRESTRESSED CONCRETE COMPANY LTD. When a Prestressing tendon can be stressed from one end only, a dead end anchorage can be used at the other end. When the anchorage is accessible, a manually blocked type jacking anchorage (Type A or B) can be used; the anchoring jaws are driven in by sledge hammer.
