German to English translations [PRO] Tech/Engineering
German term or phrase:Preßluft-Lanze
The text is a description of the "keyhole process" which involves 'Abdichtung von Muffenverbindungen'. A process for fixing leaky gas pipes I think. The first stage of the process involves:
Herstellung einer Baugrube mit Preßluft-Lanze und Saugrohr.
Explanation: If one queries "pneumatic lance" as one must do, then you only get 6 Google hits and 5 AltaVista hits, none pertinent but "pneumatic lance" still sounds like it might be the translation. One of the hits from 1998 indicates that such machines are relatively new because a guy was trying to find one without success. He used the term "pneumatic lance" but perhaps incorrectly. The word "pneumatic" itself bothers me because "pneumatic" is normally used for tools driven by compressed air, not a vacuum.
Here is a picture and description of such a machine, unfortunately only in German:
The German site refers to "Erdsaugtechnik". There are many English hits for "vacuum truck" and some with the word "lance" so it might turn out that the monster is a "vacuum truck with lance" or similar. There are also gizmos called "vacuum drills", but I could not find one with an application similar to yours.
Three technical dictionaries turn up nothing. If nobody can find anything more definite, you may have to use "pneumatic lance" and hope for the best.
Explanation: Beth's response sounds good, but looking at your sentence it seems not to fit the context. The Baugrube is most probably made by extracting the surrounding material. The Saugrohr also would reinforce this idea. Nonetheless, the idea is right. Maybe, something along the lines of extraction or vacuum lance. Really hard to say!
