for Hire in Botany and Sydney. Using the tried and tested Wirth 4-chamber rectangular suction pad transport and wall installation of almost every standard sandwich element with a smooth or slightly profiled surface is possible with the OKTOPUS® KS-/KS-e Compact.  The electrically operated vacuum pumps are supplied with energy by a 24 V DC battery system. Optical and acoustic signalling devices inform about deviations from the target state. Even in the event of a total power failure, the vacuum in each suction cup is maintained for at least 5 minutes. This ensures that the load is set down safely at all times.
