Technical development
SONNTAG runs a workshop specialized in pipe jacking machines at the headquarters
in Dörth. Our qualified employees service our complete equipment and develop our
machines.
The customers of SONNTAG profit by our exceptionally extensive technique service:
- With every transfer between aim and start excavation the pipe jacking machines are
transported and checked into our workshop in Dörth. This reduces the risk of building
site stops depending on engine trouble.
- We can individually develop and build the necessary pipe jacking machines for every
field of application under economic weight points ourselves. This optimizes the
costs for the customer.
Since 2007 our driving equipment has been provided with the CE sign. The machines
comply with all EU directives with regard to the minimum requirements concerning
technical safety as well as health, environmental and consumer protection.
