"Pit ram of any type" The subject of the invention is a hydraulic pit ram in which. h a bolt is arranged near the upper end of the lower part of the punch. This bolt serves as protection for the Eihlaas and Übedrd @ uck valve. Furthermore, this bolt is used when setting the stamp for attaching the filling device and when robbing the robbery device for coupling the robbery device. At the same time, however, the bolt is designed so that it can serve as a handle. Since the bolt is arranged above the center of gravity of the punch, the punch can easily be dragged with one hand when this is on the attacks said handle. The second end grinds 2 on the lying. Furthermore, said latch is very useful when setting the stamp.

According to the invention it is proposed for iron pit punches any construction above the center of gravity to arrange a handle so the stamp can be easily dragged with one hand and is safe when setting and can be kept quiet.

It is true that stamps have already become known in the literature, which ones are provided with a hinged bolt that helps when stealing the stamp a rope or is pivoted in any other way. As a result of the articulated connection with the lower part of the stamp, this bar does not offer a useful grip, with help which the stamp can be comfortably carried with one hand, while the foot part grinds on the lying. Above all, this bracket cannot when seated of the stamp serve as a handle to secure the vertical position.

In the drawing, as an embodiment of the invention, a hydraulic Pit stamp shown. The figures show: FIG. 1 a view of a stamp, FIG. 2 a Cross section along line 2/2 of Fig. 1 Fig. 3 a part of the stamp with ddr for Rob used auxiliary device.

The one from the lower part of the punch 10 and the extendable, piston-shaped formed upper part 11 existing hydraulic ram is near the top edge desd lower stamp 10 is provided with a firmly held horizontal handle 12, As can be seen in particular in FIG. 1 of the drawing, this handle permits 12 a comfortable handling of the stamp during transport, when robbing and also when setting.

Somewhat below the handle 12 is the filling and discharge valve 13 arranged. The handle 12 represents a protective device for the valve 13 and also for the pressure relief valve 14, which is a little lower Furthermore, as can be seen in FIGS. 2 and 3, the device 15 for filling of the pressure medium into the stamp via the valve 13 and the robbery facility 16 can be hung on the handle 12 to open the same valve 13 during robbery. In the case of the robbery device 16, it is important that it is connected to the punch remains when it has detached itself from the hanging wall. The stamp can therefore by means of the robbery device 16 may emerge from falling rock debris and pulled under the protective hand cover.

S c h u t z a n s p r u o h pit punches of any kind, thereby marked that he was in the specified manner with one above his center of gravity lying handle is provided.
