The new SENNEBOGEN 624 E taxi duty cycle crane with casing machine proved its worth in France
Speyser, a family-run company from Bas-Rhin, France, is widely known in eastern France for its expertise in special large-diameter and deep drilling operations. As a loyal partner of SENNEBOGEN, they reaffirmed their confidence in the machine manufacturer by investing in a completely new duty cycle crane concept.
One of the first construction sites to use this new SENNEBOGEN machine is located in the south of Strasbourg. Speyser drills large-diameter boreholes in a gravel pit to enable commissioning of the gravel extraction systems on site.
Speyser managing director Christophe Sprauel explains why he chose a SENNEBOGEN 624 E HD: "Our customers see great demand for drilling in inner city areas, in spaces that are becoming more and more confined. We were looking for a versatile, compact, and powerful machine that could be commissioned as soon as it arrived on site."
To address this challenge, SENNEBOGEN redeveloped the traditional lattice boom duty cycle crane and designed the 624 E, as a compact, basic unit that is quickly ready for installation with casing machines and for rope operation.
The new machine will be referred to as "taxi" duty cycle crane and uses a foldable box-type boom that can be assembled into its transport position just in three simple steps.
A real duty cycle crane with many advantages
Two 6 t free-fall winches in the uppercarriage provide the necessary tractive force. The individually adjustable free-fall brake makes operation simple and easy. With an operating weight of 27 t and a design that qualifies it to be used as a full-fledged duty cycle crane, the new SENNEBOGEN 624 E is remarkable in its class under 30 t – a unique characteristic that opens a multitude of potential applications.
"This new machine is ready to go in no time on site, and thanks to its small track width, it can be used safely in confined spaces. Despite its small size, it is very stable and particularly flexible to operate," emphasizes David Wagner, one of the company's drill operators. Although this construction site was the first to feature a 624 E, David Wagner is very familiar with SENNEBOGEN products, as the manufacturer has already supplied several machines to the Alsace-based company Speyser.
