摘要

The slab layer comprises two opposite claws (1,2) which are positioned each side of a slab (3). The claws are each fixed to an end of two connecting arms (4,5) and connected by their other end to a common articulation point (6) integral with a single lifting arm (7) provided with a gripping handle (8). Chains (9,10) each connect a point (11) of the lifting arm to a point (12,13) belonging to each articulated arm.
