Kowan – Pile Press – Still Worker

About Kowan Pile Press – Still Worker

This state-of-the-art, silent pile press enables piles to be installed and extracted in highly sensitive locations; they are compact in size so are also ideally suited to height restricted sites i.e. in buildings or under bridges and can press piles into most soil types although, depending on stiffness/density, pre-augering or water jetting is sometimes required.

After installing the first 4 piles, it travels along the installed piles using the reactionary force to press the next pile in (instead of using a hammering or vibratory action) thus creating very little noise or vibration. It’s called self-travelling as unlike other pile drivers it doesn’t need any other piece of machinery to assist it – apart from a crane that lifts the pile into the chuck of the pile press.

Further Info

The mast/chuck can incline forwards and backwards by 5 degrees ensuring a more accurate and efficient pile installation and makes working on gradients much easier.

The development of hydraulically powered, static-load sheet pile pressing equipment, was a direct response to severe constructional and environmental problems in high-density inner city areas of Japan. The Kowan range of Still Worker virtually noise and vibration free pile pressing machines are the ultimate in environmentally friendly piling.

Since we introduced the Kowan Still Worker into Europe in 1990, we have successfully completed over 750 contracts all over the world and throughout the UK.

Exclusive Mast Tilting Device is standard with each machine.

  • Virtually noise and vibration free means installation of steel piles as close as 500mm to existing structures or services
  • The Still Worker operates at ground level with no piling gates making it a very safe method of operation
  • Uses a wireless radio control providing a broad range of vision for the operator and a safe working environment
  • Still Worker is light and compact requiring only a small crane for pile pitching
    Ideal for height restricted sites
  • Every Still Worker hired from Watson & Hillhouse is supplied with a fully trained operator
