In the VDH workshop, the machine is fitted with a special leader that is mounted on the jib of the crawler crane. VDH has developed a leader mount that is suitable for both tubular and lattice leaders. A special sliding table is also built onto the crane with two guide bars on the side of the machine. Additional hydraulic functions, control options and, optionally, additional winches are also added. Of course, a capacity calculation is carried out and, if necessary, additional ballast is fitted. As a variation of the additional counterweight, part of the ballast can be replaced by a powerpack frame or a powerpack frame can be placed on top of the counterweight.
The PDX piling rig reaches greater inclinations than a PD piling rig, both forwards and backwards. In order to achieve these large inclinations, cylinders mounted on the boom are anchored to the back of the machine. By mounting outriggers at the rear, the boom can be moved backwards through the dead centre. This gives the sliding table enough travel and the desired inclinations can be achieved.
In addition to the enormous flexibility you gain when a crane can also be used as a foundation piling machine, a PDX piling rig offers even more advantages. It offers tremendous range: the PDX machine can operate forward- or backward-leaning, with a maximum inclination of 3:1. The fact that the leader can be lowered makes it ideal for work where scaffolding or a pontoon is used.

Our service department repairs, maintains and overhauls piling rigs. All our employees are experienced, highly trained and possess a great deal of knowledge. Regardless of which type of rig or make, we make sure that you have full confidence in your equipment.
Van den Heuvel has a team of mechanics with fully equipped service vans waiting for you. Our service department is experienced, well-trained, and operational throughout Europe to quickly resolve the failure of your foundation machine.
In our warehouse we have a large stock of parts. If a part is not in stock, we can order it for you and deliver it quickly.
We carry out complete overhauls, giving your piling rig a whole new lease of life in an as-new condition. But you might also opt for partial modifications. This might include cabins and undercarriages. Our service engineers will serve you either at our workshop in Werkendam or on-site.
You must be able to rely on your piling rig at all times. If the technology lets you down, you can depend on our engineers to help, either in our workshops or on-site. If you’ve suffered a malfunction, then call us on +31 (0)183 502 655 (also available outside office hours).
