Austeng has recently completed a custom built hydraulically driven “croc gate” system so Melbourne Aquarium Staff can expeditiously and safely clean the tanks of their new addition – “Pinjarra” a 50 year old, 750 kg salt water crocodile almost five metres long.

The three level Croc Liar is the centre-piece of an $8 million aquarium overhaul.

Austeng’s brief was to design a hydraulically driven (by 2 phasing cylinders) system of gates intended to confine the crocodile in its tank or in part of the land mass, particularly to keep the 700 kg croc out of the tank while the tank windows were being cleaned.  While not in use the gates stay retracted under the ground floor and are not visible to the visiting public.
