Grabo’s new Ottovac Digital brings new levels of precision and large-scale lifting capability to trade professionals working with glass panels, stone slabs, tile and other heavy materials. The digital display is the main upgrade from past product offerings. It shows current pressure readings in either psi or bar and gives a real-time estimate of the cup’s safe working load in pounds or kilograms. This takes the guesswork out of knowing how much the cup is holding at any moment.
