Darda splitter reaches 50Published 18/12, 2017 at 14:26
“It takes a keen spirit and a lot of heart and soul to realize such a groundbreaking invention. It caused my father quite a few sleepless nights at the time," said Helmut Darda’s son and successor Burkhard Darda. ”Such a creative idea is something extraordinary and continues to drive our business to this day."
The Darda rock and concrete splitter is a hand-held demolition tool that splits stone and concrete in a controlled way using hydraulic pressure. Powered by a hydraulic unit, there are four sizes available to suit application requirements.
The idea for the demolition tool came about when Helmut Darda visited a quarry, which was looking for a mechanical solution to replace the hard work of driving in wedges by hand. He came up with the idea of a hydraulic splitting principle and before long was able to increase the productivity in the quarries by a factor of ten with his new idea. Worldwide patents were granted. Initially, the splitting cylinder was designed for rock demolition, but its use for concrete demolition soon followed. The invention was an alternative to explosives and Atlas Copco offered support with worldwide distribution.
The device is particularly useful when conventional demolition work with large machines is banned. “Today, we are mainly active in the demolition industry. Keeping pace with the constantly growing needs and requirements in this industry presents us with new challenges every day,” said Burkhard Darda.
After the re-establishment of the company in 1993 and its transformation into a limited liability company, Helmut Darda’s two sons started the design and construction of a concrete shear. In 1997, they introduce the first attachment tool. At that time, it had already been recognized that the trend towards carrier-mounted demolition equipment was on the rise. Since then, Darda has continued to develop new attachments for mini-excavators and special demolition robots.
Darda has succeeded in maintaining the product’s quality and the advantages of its hand-held hydraulic stone and concrete splitting cylinder. “In the meantime, we have been able to optimize some of the weight in relation to the splitting force,” said Burkhard Darda. "But the operating principle and the basic unit have remained the same and are still in great demand."
Darda’s latest development is a carrier-mounted rock splitting cylinder that combines the splitting principle with the possibility of attachment to a carrier device, such as an excavator or demolition robot.
