Sterk has several types of pile-driving rigs:

Boom cranes with a swinging leader
This leader can be easily fitted and removed. This gives us flexibility and makes it possible to drive piles in as well as vibrate sheet piling with just one rig.

Boom cranes with leader and with leader and hydraulic extension
For heavier pile-driving we have boom cranes with a leader fitted with a hydraulic extension.

Pile-driving rigs with a fixed leader

Hydraulic hammers
Sterk has two hydraulic hammers with an impact weight of 9 to 10 tonnes. In both case we are able to control the drop height of the impact weight (force of impact).

Diesel hammers
Sterk has a wide range of diesel hammers with an impact weight of 0,8 to 6, 2 tonnes.
