Patent DE-19704510-A1 (DE)
Title: Paving-block-laying machine
Inventor: HUNKLINGER SEN ALBERT
IPC: E01C19/52
Filed: 1997-02-06
Abstract: The machine has two opposite alignment (9a,9b) and gripping (14a,14b) jaws for a layer of blocks, together with an ejector mechanism (18) thrusting an outermost row of blocks onto a base surface. One of each jaws at least, also the ejector mechanism, is actuated by a hydraulic ram (12a-22). All the rams are connected to a first hydraulic circuit. A pressure-regulating valve is installed in this circuit before the gripping ram and opens so as to supply an initial set minimum pressure. It delays operation in relation to that of the alignment ram. Seen in the flow direction of the hydraulic circuit, the ejector ram is connected to the latter after the valve, so that shutting off the gripping jaws causes the ejector ram to act against the outermost row of blocks. When the gripping jaws open, the ejector mechanism is retracted clear of the row again.
