Noon on May 8, Vessel “Zhenhua 29” slowly departed
with three quay cranes for COSCO's Greek PCT, one quay crane for COSCO's Greek
PPA, as well as one quay crane and two rubber-tyred gantry cranes for TCEEGE
project in Izmir, Turkey for the customer’s wharf.
Both of COSCO's Greek PCT and PPA wharfs belong to
Piraeus port, Greece. A total of four quay cranes with 65t rated load were
manufactured for the two projects. The lifting height was 46m. It took eight
months from manufacturing to shipment. Three remotely controlled semi-automatic
quay cranes were manufactured for COSCO’s Greek PCT. The wharf used
semi-automatic quay cranes for the first time. The driver can remote control
the quay cranes from the control center. While the operating efficiency and
safety are guaranteed, the operating intensity is largely reduced, which
provides support for the next automation reform of the wharf as well.
The quay crane for TCEEGE project in Izmir, Turkey
has a rated load of 65t and the lifting height of 51m. It has a back reach
distance of -4m, which fulfills the necessary conditions for the berthing needs
of vessels on both sides of the wharf, which brings challenges to its overall
stability. As Izmir of Turkey, where TCEEGE wharf is located, is an
earthquake-prone area, a special seismic design scheme was adopted by the
designer, which has a seismic capacity twice of that of the traditional design.
It was fully recognized by the customer.
In the early stage of project design, due to
COVID-19, customer failed to communicate with ZPMC face to face. After rounds
of communication and coordination between the two parties in different ways,
the design review and manufacturing were completed as expected. During the
operation, the project team overcame difficulties such as freezing weather and
guaranteed the timely shipment of the cranes.
