In Seldensate, aan de rand van Waalwijk, bouwt aannemer Hendriks Coppelmans 28 huurwoningen voor woningbouwvereniging Cascade. Deze Nul op de Meter (NOM) woningen staan in de nieuwbouwwijk Lommerrijk en worden prefab gebouwd. Bij deze woningen wordt de energie die nodig is voor verwarming, warm water, ventilatie en huishoudelijk verbruik door de zonnepanelen op de woning opgewekt. De woningen worden voorzien van warmtepomp, zonnepanelen en een warmteterugwinventilatie-systeem (WTW). Hendriks Coppelmans heeft Samonco ingeschakeld voor het plaatsen van de prefab delen. Samonco is een montagebedrijf uit Bree (B) en gespecialiseerd in het plaatsen van prefab betonelementen voor utiliteitsbouw, industrie en woningbouw.
Centrally located, in the middle of the scaffolding, is Samonco’s Sennebogen 5500 crawler crane. This lattice boom crane performs all common tasks such as lifting and hoisting the prefabricated walls, floors and roofs. The prefabricated panels vary in weight from 2.5 tons to 9 tons.
In the cabin we find Johan Kerkhofs, the operator of this 180-ton crane. We ask Johan about his experiences with the crane.
How long have you been an operator?
I have been doing this work for 36 years now. After leaving the service, I started working as an operator. I have 33 years of experience as an operator and have also worked with cranes from another German brand. I have been on a Sennebogen crane since 2020.
That must have taken some getting used to. How do you like it?
I was skeptical at first and didn’t have much confidence in it. But that soon changed. The crane is flexible and has a large lifting capacity. The cabin is solid and comfortable. There are no unnecessary buttons and it is just very complete.
You have been working as an operator for a long time and are still very enthusiastic. Is that because of the crane?
I am proud to work with this crane. The crane certainly makes my work very enjoyable. And that is also important because I spend more time in the cabin than in my living room.
Are there any downsides?
If I have to mention something, it is the camera. There is a camera on the ballast that was already broken after 3 months. This has been resolved properly.
Why was this specific machine chosen?
Because this machine can get close to a tall building, this is important for Samonco. You really get a lot of lifting capacity with this machine. I also understand that this machine was very competitive in terms of price.
How does the crane perform?
In 1 word: great! I am very satisfied with it. This crane with jib is up to 30 to 40% stronger than other comparable cranes with jib. On this construction site, the crane is not working at full capacity because the prefabricated panels weigh 2.5 tons to 9 tons and the crane has much more capacity. But sometimes you have these projects and you also don’t want the crane to stand still.
Do you have anything else to say about the crane as a closing statement?
If I can give a score from 1 to 10, I give the crane a 9.5. That half point is because of the camera.
