Strong silent type for Viagra factory

A NEW sheet pile installer, claimed to be virtually free of noise and vibration, is being used on the foundation contract for a pharmaceutical factory in Southampton that will eventually manufacture the anti-impotence drug Viagra.

This is the first UK contract for the Japanese manufactured Tosa Still Worker WP-150.

The machine can press up to 150t and can handle 400mm, 500mm and 600mm Larssen sheet piles. It is self-travelling and can be controlled remotely. As it operates at ground level, it is suitable for low headroom sites.

Tosa's European distributor Watson & Hillhouse brought the first Still Worker into Europe in 1990. The company claims that the silent and vibration free installation has led to many engineers choosing sheet piled retaining walls in inner-city areas instead of contiguous or diaphragm concrete walls.

The machine is the latest in the company's range and like its predecessors, features the patented mast tilting device. This allows the mast to rotate by 180 degrees, preventing slippage and damage to the piles when piling up and down a gradient and helping accurate installation. The chuck can also rotate 90degrees both clockwise and anticlockwise while holding a steel pile which allows pressing corner piles in any direction.
