Abstract
1. Clamp for plate-like concrete elements particularly for laying units (13) comprising loosely engaged concrete paving stones, for receiving, transporting and placing (laying) the same with a barrow-like laying means, wherein the plate-like concrete elements are engageable by at least two clamping jaws (16, 17) is arranged on a two-armed lever (21, 52, 52) subject to the action of a pressure member (26, 55), the power arm (22) of said lever (21, 51, 52), the power arm (22) of said lever having a multiple of the length of the load arm (20) receiving clamping jaws (17), characterized in that the pressure member comprises a toggle lever (26, 55) having at least one toogle lever arm (30, 31) formed from two telescopic parts (33) braced against one another, particularly by elastic pressure means (35).
