The development of hydraulically - powered, static-load sheet pile pressing equipment in response to severe constructional and environmental problems in high-density inner city areas of Japan provides a very quiet method entirely free from vibration.
Since we introduced the Kowan Still Worker into Europe in 1990, we have successfully completed over 750 contracts in Germany, France, Benelux, Switzerland, Denmark, Italy and throughout the UK.
Features/benefits
No noise or vibration allows piling in built-up areas and in close proximity to existing services. Drives and extracts 400mm/500mm/600mm 'U' profiles and 'H' piles Up to 150 ton pressing capacity Self travelling means only a small crane is required for pitching and it can work in low headroom areas. Radio controlled and no piling gates required means a productive safe working environment. Unique Tilting Device allows piling up or down a gradient. Turns corners and curves Cost effective alternative to concrete retaining walls i.e. contiguous and diaphragm walls.
Every Still Worker hired by Watson & Hillhouse is supplied with a fully trained operator.

Still Worker Self Travel Operation
1. Still Worker is set on the reaction stand for the first two or three sheet piles.
2. Still Worker moves by elevating its travel carriage while supporting itself on the last installed pile.
3. Travel carriage then slides forward.
4. Travel carriage lowers itself and then drop onto the installed sheet piles and continues its hydraulic installation process. After the third (or fourth) pile is driven, Still Worker moves off the reaction stand to travel independantly on the piles.
600mm
500mm
400mm
In case of 400mm-pitch, normally 2 clamps are used. The drawing however show the use of an optional No.3 Clamp when enough reaction force cannot be obtained.
Patented 'Mast Tilting Device' is employed as the standard device with each machine.
180° turning function can offer continuous piling from straight on piling to corner piling
*All the models can install U-sheet piles manufactured by HOESCH, Arcelor and Eastern European Larssen Sections depending on the applicable
range of each model for sheet piles.
