Cranes make life easier

The lifting was and is a key problem in the art history of mankind. A
big part of the cranes. Not that you could not build great buildings
without cranes. The Egyptian pyramids were all built without a crane
and are still over 100 m high. A lot of work would be spared but the
Egyptians, they were aware of cranes. Also, not sure 100,000 workers
in the construction of a pyramid would have been involved. The
technique of the cranes was already known to the Romans, but used
wisely it was not until the Middle Ages. Many churches and cathedrals
could only grow thanks cranes in the sky. Crane also brought great
relief in ports and mining. Meanwhile, the technology of the cranes is
considerably more sophisticated, but the principle is the same: loads
to be lifted and the work area of ​​the crane can be transported.
Roughly speaking, there are tower cranes and mobile cranes, which are
presented in more detail.

When the roof is lifted

Eventually, every family with adolescent children is the same problem.
The children take up more space. Now, good advice is expensive. Build
a new house - costs too much. Grow - is usually not due to limitation
by Zoning. Remains only one thing - grow up. So the attic is
inspected. Would be enough space available, but stand up is only a few
square meters. If it were then actually building the brick knee wall
just a bit higher! Now this is way too expensive? The old roof
dismantled and disposed of. Create a new roof. This strained the
finances of your household budget exceeds by far, you think.
Hydraulic lifting system for lifting roof
However, there is a simpler and cheaper method primarily. The roof is
raised hydraulically, then backed up the knee wall! Made possible by
the patented Dino-lift system from Klaus construction technique in
Bobingen near Augsburg. When lifting of the roof of 80 cm results in
about 30 percent more living space. The cost of a roof at a family
home and are raising a raise the roof height of 0.80 m to 1.50 m
between 5100 and € 12 800 €. In the conventional method must be
reckoned with costs of at least € 6900.
