Technical answer
What is a post tension hydraulic jack?
Definition
The post tension hydraulic jack is the stressing unit that applies the tensioning force to post-tensioning strand. It is precision controlled with a digital load display for accurate stressing force application, and it covers 15 to 650 tons capacity with a 150 to 300 mm stroke. The jack works with 12.7mm and 15.24mm strand and is manufactured to EN, ASTM and PTI requirements.
Typical applications are the stressing of post-tensioning tendons on bridges, buildings and other prestressed structures, where the jack is used with the matching anchorage, wedge set and hydraulic pump. It can be driven by an electric or manual pump, and the compact body keeps the unit portable between stressing positions. Global Overseas supplies the jack together with the pump station and post-tension accessories used on the same site.
Specification
What to state in the RFQ
Required capacity (15 to 650 tons), stroke (150 to 300 mm), strand size (12.7mm or 15.24mm), pump type, control requirement, quantity and any calibration or inspection requirement.
Compatibility
Compatibility
Confirm the anchorage, wedge set and pump that the jack will work with before ordering. Jack selection must follow the project engineer’s stressing schedule and the anchorage supplier’s compatibility requirements.
