Increased flexibility in the gravel pit
With the expansion of the extraction area, the Bokshorn gravel pit also needed to purchase new extraction equipment: effectiveness and flexibility were at the top of the list of requirements. With the SENNEBOGEN 6100 E duty cycle crane, the gravel pit found a tailor-made solution that not only perfectly meets its needs, but also scores points with its low consumption.
Gravel pit extraction area extended
The Bokshorn gravel pit in Porta Westfalica, North Rhine-Westphalia, is a family business with a long tradition. Founded back in 1882, the gravel works - now in its third location - still produces around 150,000 tons of sand and gravel for the concrete industry, including for prefabricated construction and paving stone works, every year. When the current managing partner Henrik Franke took over the business from his father in 2024, the gravel pit's extraction area was expanded. In order to be prepared for the new area, the machinery also needed to be updated in good time. The old electric but inflexible scraper plant was therefore replaced by the 100-ton SENNEBOGEN 6100 HD duty cycle crawler crane.
Tailor-made for the application
"When I was looking for a more flexible solution for our extended mining area, I quickly came across the duty cycle crawler cranes from SENNEBOGEN. Through the dealer Louis Scheuch, we were initially able to approach our needs with a 70 t rental machine and finally landed on the 100 t duty cycle crawler crane with 3.5 cubic yard dragline bucket ," reports the managing director of the gravel plant. "For us, effectiveness is more important than speed. We want to act sustainably and exploit the full capacity of the gravel deposit. That's why the desired digging depth of 12 m determined the machine size." Thanks to the fairlead and the deflection pulleys integrated in the boom, the rope of the duty cycle crawler crane is guided optimally and gently. The machine and dragline bucket can be controlled safely and precisely and excavation can be carried out gently and with maximum accuracy . The 29.9 m long lattice boom, which is ideal for heavy, dynamic operation in the gravel pit, also allows the material to be lifted with the dragline bucket far in front of the machine so that the edge can be left standing for as long as possible.
Flexible across the entire site
"All in all, the new duty cycle crawler crane solution is much more efficient, elegant and flexible than before. And not just in terms of location," Franke continues. Thanks to the crawler undercarriage, the employees at the gravel works can easily move the 6100 HD to wherever it is needed at any given moment. The areas of application for which it has already been used are correspondingly diverse : from renaturation measures to digging a canal for the undisturbed water supply of the pump - a task for which an external company would otherwise have had to be commissioned. The machine is currently being used again in the old mining area. This is also no problem for the new flexible duty cycle crawler crane, which, unlike the old system, does not require a power supply.
"Looking back, I find the whole project an exciting process...
...and a journey with great success. Everyone worked together to ensure that we now have a customized machine that is perfect for our purposes. Above all, Mr. Bräutigam from Louis Scheuch was very committed throughout the entire period and the contact persons from SENNEBOGEN were always available."
"We usually operate the SENNEBOGEN 6100 E in a low speed range, so the fuel consumption is pleasingly low . The machine has enough power for our purposes," says Franke happily.
Cable excavator project: A success all along the line
The cable excavator project is a success across the board: from the initial contact with Louis Scheuch, to the provision of a rental machine, to the final installation on site. The feedback from the machine operators Yury Starodub and Alexander Chernyshov is also purely positive. They are proud that they got to grips with the complex application so quickly.
