In May of 2012 Mr Cropper was presented with an Innovation Award from the Urban Superway Project in Adelaide SA.
This was awarded for introducing the CFA Cropper technique for breaking down the piles to cut off level.
The use of the cropper Increased production time, decreased costs significantly and reduced the risk of manual handling injuries through the use of Jack Hammers.
It also reduces the risk of damage to the pile integrity and any cracking through vibration and does not damage the steel.
Dust is also reduced significantly again improving working conditions and the environment.
This is also the preferred method for breaking down all piles and is seen by the piling contractor has the preferred method and choice so as to reduce damage to the piles integrity.
HAVS (Hand Arm Vibration Syndrome) or VWF (Vibration White Finger)
HAVS (Hand Arm Vibration Syndrome) or VWF (Vibration White Finger) ... WHY RISK IT ??
HAVS is a widespread recognised industrial disease affecting tens of thousands of workers.
It is a disorder that affects the blood vessels, nerves, muscles and joints of the hand, wrist, and arm. It's best known effect is vibration-induced white finger (VWF), a term introduced by the Industrial Injury Advisory Council in 1970. Injury can occur at frequencies between 5 and 2000 Hz but the greatest risk is between 5 and 150 Hz.
Excessive exposure to hand arm vibrations can result in various patterns of diseases casually known as HAVS or VWF. This can affect nerves, joints, muscles, blood vessels or connective tissues of the hand and forearm:
- Tingling 'whiteness' or numbness in the fingers (blood vessels and nerves affected): This may not be noticeable at the end of a working day, and in mild cases may affect only the tips of the fingers. As the condition becomes more severe, the whole finger down to the knuckles may become white. Feeling may also be lost.
- Fingers change colour (blood vessels affected): With continued exposure the person may suffer periodic attacks in which the fingers change colour when exposed to the cold. Initially the fingers rapidly become pale and feeling is lost. This phase is followed by an intense red flush (sometimes preceded by a dusky bluish phase) signalling the return of blood circulation to the fingers and is usually accompanied by uncomfortable throbbing.
- Loss of manual dexterity (nerves and muscles affected): In more severe forms, attacks may occur frequently in cold weather, not only at work, but during leisure activities, such as gardening, car washing or even watching outdoor sports and may last up to an hour causing considerable pain and loss of manual dexterity and reduced grip strength.
As an employer – Can you afford to break concrete piles down by hand?
