Abstract:
A stepwise conveyor device for the transport of massive objects, comprising: a fixed series of laying stations distributed along a longitudinal displacement direction and centered on transversal planes spaced apart by a constant pitch and at least a mobile series of recovery stations spaced by the constant pitch and arranged on at least one longitudinal supporting beam vertically between a lowered position and a raised position for which the recovery stations are placed, respectively, below and above the laying stations, and longitudinally between a backward position and a forward position for which each recovery station is centered, alternately, on the transversal planes of two successive laying stations, the supporting beam resting on the floor on at least two vertically and horizontally sliding bearing members, of adjustable height extending vertically over at least one portion of the height of the beam, the sliding bearing members comprising, respectively, at least two actuators for level adjustment in a synchronous fashion and associated with at least two horizontally sliding guiding means of the supporting beam enabling longitudinal displacement of the said beam, respectively in a forward direction in raised position and in a backward direction in lowered position, whereas each actuator comprises two elements resting in opposed vertical directions, respectively on the beam and on the floor, for determining a rigorously vertical displacement of at least two bearing points of the beam.
