The tunnelling machine is equipped with a jet pump and an integrated hydraulic power unit. With conventional methods, restrained inside space limited muck removal over longer sections and as a result also limited the possible drive lengths.
'Repair' is our smallest project volume for small budgets or full timetables - or simply for good machines with a small problem only. We only repair exactly what you want us to and add a standard outgoing test if desired.
If necessary we will make suggestions about what else should be done shortly or in the future. 'Repair' can be done both in our workshop or on your site or yard.
Typical examples would be to unclog a greasing system, to fix hydraulic problems or a leaking bypass or to change a hydraulic pump or an electronic component of your steering container.
'Service' is our standard, often combined with repairs. Recommended after a number of drives, during a winter break or before a more complex project starts. We do a profound checkup of your system, including all necessary maintenance works, change of wear parts according to your wishes, cleaning out your hydraulic system and electronic components, have a system backup made for you and finish with a comprehensive outgoing test.
Typical examples are a checkup of a steering container including a filter and oil change, a machine service with bearing oil change, change of hydraulic and slurry hoses or a service of a jacking frame including reconditioning the push cylinders by a specialist company.
'Full Rebuild' is what we are proud of. We can offer to refurbish your machinery at highest quality standards. Recommendable after a serious damage during a drive, before or after selling or buying used machinery or simply to save old machinery that has been lying still for a while.
We take your machinery apart, piece by piece and replace every seal, wear part or bolt. Also all cables and hydraulic hoses will be replaced, the naked steelworks will be either fully replaced or repaired where necessary, then sandblasted and painted in coats. The key components will be tested and then replaced or reconditioned by either the manufacturer or renowned German specialist companies; all other will be replaced where necessary.
In the end your machine will be like new - at a fraction of the cost of a new machine. As the service range differs widely with what component is to be fully rebuilt, please find more details below.
