The invention relates to a mobile installation for the vibration of light concrete, such as gas-formed cell concrete. According to the invention, the installation consists of two upper and lower rolling tracks (1 and 5), respectively, each of them having an upper and a lower rolling system (2 and 6), respectively, driven by a driving unit (11), allowing the motion of a mobile cross-beam (3) supported by a column (4), a telescopic arm (7) being mounted on the cross-beam (3), at the end opposing the upper rolling track (1), to said arm (7) there being attached a rectangular frame (8) on which there are mounted some vibrating blades (9), each long side of the rectangular frame (8) being formed of a fixed part (8') mounted by an articulation (10) to a mobile part (8'') which can be swung together with the corresponding vibrating blades (9), where the mobile parts (8'') are sustained by some cables (15) passing through a guide roll (14) placed on the telescopic arm (7), the telescopic arm (7), the vibrating blades (9) and the mobile parts (8'') being driven by another driving unit (13) mounted on the mobile cross-beam (3). |
