摘要：: In advancing cylinders installed in such a way as to be moved into line, the force transmission between the piston rod and the powered support assembly takes place via a U-shaped bracket which encloses the piston-rod head from above and is connected to the latter by a pin. The space between the floor skids of the powered support assembly for the debris to flow off is consequently narrowed. The dimensioning of the pin must be geared to both tensile and shearing forces. The bracket must have corresponding bores for accommodating the pin. The invention provides a vertically slotted piston-rod head 7 in which a narrow hook 15 of a bracket 17 engages. This narrow type of construction creates more space for the debris to flow off. The pin 13 merely needs to be matched to the force for advancing the abutment. The hook 15 can be designed as a simple flame-cut part. Pin locks are omitted. <IMAGE>
