4a - 74 to be able to break down mechanically with success. We already spoke under 1) of explosives, which are often even smaller than the so-called vibration charges in the well-known literature, because, in a sense, these vibration blasts were carried out not even with concentrated charges, but with series loads and individual drill cartridges, so such pre-emptive charges are to be taken far smaller for mechanical work. One comes in the minimum to individual loading quantities of l/2 drill cartridges, especially if one does not want to disturb the other work at the damage site near the blasting. After the previous exportations it is clear that the mechanical removal of buildings or their parts often only represents the extension of the detonation process, insofar as the removal of debris here and there exposes places where the remains are mechanically required to be laid down, especially since it is not worth blasting. For mechanical tearing or overturning work, the well-known break-in hook in boat hook form plays only a sub-ordered role for small and smallest work. Its use is of course. The further needed auxiliary devices are especially: 1.) Free-standing ladders (mechanical ladders), ordinary ladders 2.) Shock or storm beams, best suspended by commuting or the 25 - 50 kg iron drop ball suspended by wire rope. Except -75
