The driving cap ensures a good transfer of the energy of the driving impact into the sheet pile and thus prevents damage to the pile head. Driving caps are made of cast steel. The underside of the driving cap is provided with grooves that have a wedge-shaped widening towards the bottom to make it easier to place the driving cap on the sheet pile wall. At the same time, the arrangement of the grooves allows different profiles to fit into one driving cap, thus each driving cap model can be used for several sheet pile profiles.

B. Lining
C. Leader

The distance from the centre of the bear to the leader guide must correspond to the distance from the centre of the pile to the leader guide. On the top of the driving cap is a recess into which the pile-driving lining, usually made of hardwood or plastic, is inserted. The lining dampens the impacts of the ram.

Driving caps for HOESCH and LARSSEN sections/piles and UP piles
Available are single and double driving caps. Driving caps with wooden cushions or, if specially requested, with overlapping steel/plastic linings.
