Claim:
1. A lifting beam device for lifting and/or displacing a load comprising: a lower beam positioned longitudinally; an upper beam positioned longitudinally above the lower beam; a guide configured for allowing vertical sliding of the beams one relative to the other; an engager configured for arranging the beams in close and releasable engagement with one another; and grippers at the longitudinal ends of the lifting beam device configured for gripping the load, the grippers configured for being maintained in an open position when the upper beam and the lower beam are engaged with each other, the grippers configured for assuming a closed position when the engagement device is released, each of the longitudinal ends of the lifting beam device including one of the grippers, each of grippers comprising: a slide attached to one of the upper beam or the lower beam and slidably mounted vertically relatively to the other of the upper beam and the lower beam; one of the guides forming a guiding rail fixed relatively to the other of the upper beam and the lower beam; and two arms symmetrically mounted relatively to each other, relatively to a vertical longitudinal plane, a first end of each arm being guided by the rail, a second end of each arm being adapted for engaging with the load, each arm being jointed in an intermediate point in rotation relatively to the slide, the rail comprises a guiding area designed for having the arms swing between an open position and a closed position, when the slide slides relatively to the other of the upper beam and the lower beam.
