Hybrid cranes to cut emissions in Tanzania

Tanzania Ports Authority (TPA) has invested in diesel-electric rubber-tyred gantry (RTG) cranes for fuel savings, low emissions and easy maintenance.

Hybrid Kalmar RTG

Kalmar has signed a contract to supply TPA with a total of six hybrid Kalmar RTG cranes for use at Dar es Salaam port.

Mikko Mononen, vice president of sales, EMEIA at Kalmar, said: “The relationship between TPA and Kalmar goes all the way back to 1987 when we delivered our first diesel-electric RTGs to the customer. As one of our longest-standing customers, we are very pleased to continue our collaboration going forward and look forward to supporting them in achieving their strategic objectives for Dar es Salaam port.”

Low maintenance

At 1,000 hours, the RTG cranes have one of the longest maintenance intervals in the industry, while their modular design makes it easy to tailor to customer requirements.

The units delivered to TPA will be configured to handle 6+1 wide with 1-over-5 high stacking and will have a lifting capacity of 40t under the spreader.

They will also be equipped with a variable speed generator, which enables even greater fuel economy and lower emissions by automatically optimising RPM according to the required power.

Dar es Salaam port handles about 95% of Tanzania’s international trade and serves the landlocked countries of Malawi, Zambia, Democratic Republic of Congo, Burundi, Rwanda and Uganda.

Delivery is scheduled for Q1 of 2021.
