Super-sized crane arrives in Port Botany
Port Authority of New South Wales assists with the safe arrival of a super-sized container crane for Port Botany’s Brotherson Dock.
Port Authority’s Port Botany team had their hands full as they helped prepare for the arrival of a giant crane — one of the port’s biggest ever deliveries.
The new $14million crane, made by specialist manufacturer ZPMC, stands over 73 metres high and weighs in at 1200 tonnes with a boom that reaches 105 metres in the air at full height. The crane is so big it can casually lift around 75 tonnes — the equivalent weight of a Boeing 737 with passengers.

The new crane is built to service large vessels that carry up to 10,000 containers and will meet the changing needs of visiting container ships as they grow in size to meet Australia’s ever-growing import demand.
The crane arrived on board the heavy bulk carrier, ZHEN HUA 21 along with two other cranes destined for DP World Australia’s Melbourne Terminal. The crane extended beyond the ship’s side and an arrival beam width of around 120 metres had to be negotiated by Port Authority’s marine pilots.

Maintaining Port Botany’s shipping schedule also proved challenging for Port Authority’s vessel traffics services (VTS) team who help ships navigate safely through the port’s waters. All vessels with a length of over 300 meters had to be carefully manoeuvred around the ZHEN HUA and its extreme load to maintain a safe distance.
To add to the challenge, the close proximity of Kingsford Smith Airport meant that the movement of these large cranes through the port could only be done at night during curfew hours (2300–0500).
A series of permissions from the aeronautical regulators also had to be obtained to allow air draft limits to be exceeded for a short time while the cranes headed into the port.
