Liebherr Scores Several RTG Orders

DP World Asian Terminals Inc. has placed an order with Liebherr Container Cranes for a further five RTGs at its Manila facility following an order of two units that were commissioned earlier in 2014 at the port.

The RTGs feature numerous environmental, safety and productivity technologies, Liebherr said. An eco-friendly variable speed drive will reduce both emissions and fuel consumption per box moved, and the advanced DGPS auto steering and box positioning system is complemented by auto steering, a stack profiling system featuring a safe path calculator and a truck positioning system to boost productivity and ensure safe operation.

The eihgt wheeler RTGs stack one over six high-cube containers, have a safe working load of 41 tons under spreader and span six containers wide and a truck lane. The machines benefit from Liebherr’s unique eight-rope reeving no-sway system and simultaneous motion of all drives allowing the RTG to attain productivity levels of up to 40% greater than alternative models, according to Liebherr.

Liebherr Container Cranes have recently secured a contract for the delivery of four Electric RTGs to the Port of Longoni in Mayotte. The Cranes which are due for delivery in 2015 are capable of working seven stacks wide and a truck lane and can stack one over five high and have four wheels per corner. The cranes feature dual power with a cable reeling drum complemented by a diesel genset, allowing the port the flexibility to choose power supply depending on operational requirements. These are the first Liebherr RTGs to be delivered to Mayotte, a French department consisting of a number of Islands located between Mozambique and Madagascar.

Liebherr is also shipping eight Electric RTGs to Porto Chibatão, Manaus, Brazil, a major port at the confluence of the Amazon and Rio Negro rivers. The RTGs are supplied with a cable reeling drum and diesel genset and have the option to operate either fully electric or with diesel power. The machines work stacks of up to eight containers wide and six high and have a safe working load of 40.6 t. The RTG’s join the existing fleet of six RTGs and nine fixed Liebherr Cargo Cranes at the port.
