Cordeel is firmly committed to the energy transition of its equipment service. The ambition? Emission-free construction sites, despite all the challenges surrounding investments, infrastructure and power supply. A special project within this transition is the conversion of the 120-ton Sennebogen 6113 – also known within the company as “The Beast”. The machine was completely converted from diesel to electric by Van den Heuvel, including a large electric motor and a powerful battery pack. In order to be able to use it at locations without a power supply, a smart range extender was added: an emergency generator that can both drive the hydraulics and charge the batteries. With this solution, the crane is completely future-proof – can be used at regular and grid congestion-sensitive locations, without compromising on performance. A good example of customization, in line with Cordeel’s broader vision on sustainable construction logistics and energy management.
The Sennebogen 6113 is now in full operation on the Maasvlakte. We asked Jaap Hoekman (Head of Materials Department) and Marc Bosma (driver) about their first impressions.
What does this project entail, what is being built?
“A switching station that converts high voltage from wind farms to medium voltage. There is a shortage of power capacity in the Netherlands. This is a government project that contributes to the energy transition.”
Is there a special construction method used?
“Yes, the construction is high, heavy and completely airtight.”
How long will the project take?
“The station must be operational by the end of 2026.”
What makes this project special?
“The size and requirements make it unique – even on a global level.”
Which tasks does the crane carry out?
“Unloading and placing heavy prefabricated concrete elements, such as columns and roof beams.”
How heavy are the elements that are being lifted?
“Between 26 and 28 tons, at a reach of 14 to 26 meters.”
Are there any specific challenges?
“Certainly. The crane places heavy wall elements between existing columns, at a distance of about 20 metres – while the roof is already closed. That requires extreme precision.”
How is the machine loaded in practice?
“That’s going well. It would be useful if the machine could be charged via the undercarriage, so that the upper structure can continue to run.”
Why was this crane chosen?
“The Sennebogen 6113 is strong, heavily built and very manoeuvrable – a real beast of a crane. Ideal for this type of work.”
Does Cordeel have other Sennebogen cranes in its fleet?
“Yes, we also have a 640R HD, a 683E and two 643Es.”
Is this the first electric crane in your fleet?
“Yes, this is our first electric crane. We opted for an electric version because of our sustainability ambition and the demand from clients.”
We also speak with Marc Bosma, the driver. Marc has been working on a Sennebogen crane for over 25 years. First 20 years on a 640R HD and then on the 6113 that was purchased in 2021.
What are your experiences with this electric crane?
“Very positive: it is strong, manoeuvrable and robust. It runs smoothly, very quietly.”
What is the difference with a diesel variant?
“The electric crane is quieter and faster in response.”
How long can you work with a full battery?
“Between 8 and 10 hours. This of course depends on the work being done with it. If you drive a lot, it uses more power and the battery runs out sooner.”
Would you recommend the crane to others?
“Definitely. It is a great machine!”
