Hydraulic free fall hammer

The hydraulic free fall hammer consists of a cast steel shell which is filled with a metal alloy. The fill ensures powerful impact performance combined with optimum noise damping. The impact surface is adapted to the piling to guarantee long hammer life. Impact energy is infinitely variable from 10% to 100%.

The hammer is driven either directly from the carrier or from a separate power pack. Guide claws are available to guide the hammer on all types of leader either perpendicularly or up to an inclination of 1:1. Free-riding use with pile guides or guide frames is possible without difficulty. The control unit can be installed in the carrier cab, in the power pack or elsewhere depending on customer requirements.

Applications:
The MHF hammer is suitable for driving all kinds of piles in land, marine and offshore applications, including conductor piles and smaller offshore piles.

Diesel hammer

Diesel hammers are mainly used in foundation work in the construction industry to drive sheet piles, precast and cast in-situ concrete piles, tubes etc. as well as to determine the load bearing capacity of driven piles. They are suitable for all piling sections and are used both as free-riding units and in combination with leaders. The hammers have their own energy source and consume only little fuel and lubricant.

Because of their unmatched impact power these machines are the preferred choice for piling jobs involving a large degree of soil displacement and pile friction. Diesel hammers are made in various categories from the D6 with 600 kg ram weight to the D200 with 20 t ram weight. The D200 is mainly used in the offshore sector to drive foundations and casings, e.g. for oil platforms and wind turbines. Diesel hammers are low-wearing, low-maintenance machines offering maximum driving efficiency.

Advantages:

Low consumption due to on-board energy source;
environmentally friendly
Robust construction
Reliable and simple to operate
Suitable for all piling sections
Cost-efficient thanks to long operating times
Controllable impact energy;
an advantage when dealing with changing soil types

Drilling rigs

Drilling rigs are used for varying drilling jobs and soil types – from mud to rock. Care must be taken to ensure that the equipment is matched to the job. Drilling rigs are suitable for piles up to a diameter of 2000 mm and a depth of 60 m. Thanks to their compact design they can also be used without difficulty on confined building sites. The rigs are also used for inclined drilling and driving.
