Controlled prestressing before centrifugal forming

A pile tensioning machine applies the specified prestressing load to the reinforcement through the mould-end anchorage system. It is selected as part of the mould and reinforcement assembly, not from pile diameter alone.

The tensioning station must connect correctly to the mould and reinforcement anchorage. Force, elongation and the operating sequence are defined by the approved pile design; equipment selection also considers access and the method used to verify the applied load.

Configuration and integration

  • Required tensioning force and working stroke
  • Mould-end connection and anchorage interface
  • Load measurement and control arrangement
  • Operating records and line-control interfaces

Information for equipment selection

Prestressing design, reinforcement details, mould-end drawings, force and stroke requirements and operating sequence.

Selection questions

Which inputs determine the tensioning equipment?

The approved prestressing design establishes the required force and verification method. Equipment selection also needs the working stroke, anchorage connection, available access and the sequence used at the station.

Can a tensioning machine be added to an existing mould line?

An upgrade requires review of the existing mould ends, anchorage details, reaction arrangement and controls. Connection compatibility and load capacity must be established before a replacement or retrofit scope is proposed.

Supply and project coordination

Realjet can include the pile tensioning machine in a coordinated spun pile equipment package or review it for an existing production line. Equipment dimensions, capacity, controls and supply boundaries are confirmed against the project requirements before an equipment proposal is finalized.
