High-speed pile driving in South Africa with HB 2000 hydraulic breakers
It has been said that the levels of solar radiation in South Africa are the best in the world, and the country has a rapidly emerging solar energy industry with a number of project sites in the Northern Cape. Geopile Africa is currently installing piles at sites for solar projects in the region using the Duktus piling system in combination with Atlas Copco HB 2000 hydraulic breakers. The high power and blow frequency of the HB 2000 are major advantages for pile-driving operations of this type.
400 blows per minute
The Duktus piling system concentrates 4,000 Joules of energy per blow of the hydraulic breaker down onto the pile-driving shoe, and with the breaker delivering at a rate of 400 blows per minute this enables piles to be driven easily and rapidly through harder abrasive layers of material in the upper soils.
“So far our average pile production rate is 5 minutes per pile and with 4 piling rigs on site we can install up to 400 Duktus piles per day,” says Jared Prowse. “That is the production rate that I have been aiming for because these projects require us to install over 50,000 piles in a working period of just over 6 months. My aim is to complete all of these works safely and ahead of schedule for my clients.”
HB 2000 – powerful and user friendly
The breaker is also equipped with the PowerAdapt system which shuts down the breaker if the oil pressure is too high – a useful feature when the hydraulic breaker is used on different carrier units.
