The products from Demarec, a member of the Kinshofer Group, always perform top, also shown in the following story from Mark Lommerde, technical director at the Dutch company Gebroeders De Koning, which is working in the civil as well as street and waterway construction.
Gebroeders De Koning is based in Papendrecht and has recently bought its second Demarec demolition and sorting of the DRG-series (D-HP-HD) to carry out underwater works. 

 

Lommerde: “When we were working at the banks of river Schie in Holland, fixing frames there, we came across so much debris, that it was impossible to place a piling wall without first removing gravel, washed up wood and iron from the ground.” 

 

 

To make that happen we used a Demarec DRG with a special modification. A hole was drilled into the rotor’s housing to prevent too much dirt being collected inside, that could damage the mechanism.”
He adds that is had been part of the same project to place the cornerstone for the pier protection beforehand.
Lommerde describes the relation with Demarec as very pleasing. “There are no long waiting times and the employees always think outcome-oriented in collaboration with the customer. When we ordered the second grab, they visited us to make sure what kind of modifications had to be done. And they deliver high-quality products, that is why we only use DRG-grabs in the water.”


The company Gebroeders De Koning is a medium-sized construction company with a proper engineering office. They also have their own equipment service with a wide range of machines and attachments like foundation machines, cable cranes and earthmoving tools. Main activities are civil works, geotechnical design, concrete works, water construction, foundation works, earth retaining structure as well as maintenance.

 


Sustainable entrepreneurship is extremely important for the company. Besides a healthy business establishment, the company always considers the effects of the actions on the environment and never loses sight of the human factor in and outside of the company.
