Our RIGHETTI vacuum lifters and lifting systems are designed and built to optimise working times to the maximum, by offering a strong and easy to use product. The vacuum lifter is a lifting accessory, which, thanks to the vacuum created by a vacuum generator, permits fast and easy attachment, lifting and handling of slabs and semi-processed made of marble, granite and other material. The vacuum is created by a vacuum generator supplied with compressed air (it just needs to be connected to the compressor) or an electric pump (independent or to be applied to the machine). In relation to the dimensions of the material to be moved, the vacuum lifters comprise of one, two, three, four, or more vacuum pads, adjustable both longitudinally and transversely, with total load capacities ranging from 80 to 3000 kg. The vacuum pads have special seals to guarantee grip efficiency. The dimensions of the pads vary on the basis of the weight of the material.
The structure of the vacuum lifter may be manually tipping or with the aid of a pneumatic piston, which permits easier material handling from the horizontal position to the vertical (0°-90°). The vacuum lifter is then fitted to a lifting device such as a bridge-crane, jib-crane, suspended system, forklift, etc. |

A SERIES OF COMPONENTS GUARANTEES MAXIMUM GRIP SAFETY.
The grip and release of the slabs is effected by commanding a double action slide valve, with safety against involuntary start-up. A vacuum gauge with coloured scale installed on the vacuum circuit permits constant control of the vacuum reached.
A vacuum switch fitted to the vacuum tank regulates safety device intervention.
The vacuum tank, in addition to accelerate the grip, coupled with a non-return valve guarantees that the load is not immediately released if there is a sudden supply interruption thus ensuring the safety of the operator and of the transported material.
The vacuum lifter is also provided with an acoustic and visual alarm system, supplied autonomously and alerts the operator on possible dangerous situations. |
