Menck constructed piling plants since 1870. First, piling drive hoists were produced, which pulled the piling drive block at the piling frame towards the top, there being released, falling down, lifted again and so on. Thereafter  the first piling plants, constructed with frames produced out of iron, were produced.  These frames were equipped with screw spindles and so were able to be inclined.  The frames became movevable on rails, but weren`t  revolveable. It was equipped with a standing cross-tube steam  boiler, a steam driven piling drive hoist, a free falling hammer, a reversing rope and monkey.

Piling plants with monkeys were only able to do a small number of hits, because the monkey had to be lower again after every hit, to move the hammer (simple casted block with suspension eye) at the frame, back to the top.

Later piling plants with endless chains were built. The free-falling hammer had a moveable “nose”, which immediately after the stroke was linked by hand into the continuosly revolving chain to be brought up to the desired height. Being there a rope was torn, the hammer was released, felt down and hit.  The number of strokes was  increased considerably, because there was no need anymore to wait for the return of the monkey. This construction  was out-dated quite fast, because the direct effecting steam hammer got more and more accepted. The idea, to bypass the  winch of the steam hoists and to use the steam directly within the hammer,  arose for the former inventors quite quickly. Its realisation became real in 1883, when the so called “Lacour-hammer” was built. That`s a simple steam-cylinder with control bar on the cylinder cover and with downwards hanging piston bar, which was seated on the hammer rail. This system had a few faults, which inspired Menck&Hambrock to make some improvments. They found the direct impact menck-steam hammer with a continous upwards going piston bar.

This hammer was paid a lot of attention to. But the stroke had still to be controlled by man. Additionally the used steam  had to be pressed out of the hammer during the fall , like it had to be with the “Lacour-hammer” and the expansion power of steam couldn`t be completely used, because of the manual control. This faults lead to the new semi-automatic Menck-steam hammer, like it was  produced until 1978.

The hammer operated automatically, in other words, the rising hammer cylinder automatically reverses in such a way-by means of the control bar of the control piston on top of the cylinder cover-that the steam contained in the space above the piston which causes the hammer cylinder to rise, can escape through the exhaust vent at the foot of the hammer. The hammer stroke as hard as the freefalling block, but wasn`t slowed down by steam any longer. The shortly before the  turn of the century developed concrete piles were a big challenge for the piling rigs constructors, because these piles were very sensitive. Now the universale concrete pile driver were offered. This frames were offered at different sizes with steam hammers with up to 6000 kg falling weight. The pile driver was rakeable and revolveable. For driving concrete piles a pile-helmets is needed.

Finally in 1934 the Menck tubular frame piling rigs were introduced. These frames were lighter, more moveable and less personal was needed. These frames could easily be assembled and dismantled.

In 1935 a new hammer was offered, the so called “double-acting pile hammer” typ SB.
