For these models, Gottwald offers a wide range of variants to meet individual customer requirements in terms of crane type, lifting capacity, hoist speed and drive power which, together with an order programme, allow for highly individual solutions and short delivery lead-times. Since the launch of Generation 5 at the beginning of 2006, 79 units have been sold.
“Model 4 is an entry-level model for the diversified 100-tonne class market and is also offered in several variants, including a 4-rope-grab for professional bulk handling. And like our Models 6, 7 and 8, it is offered not only as a mobile harbour crane on a tyre-mounted chassis, but also as a portal harbour crane and as a floating crane on barge,” said Dr. Mathias Dobner, Gottwald’s CEO.
Model 4 has a working radius of up to 46 m, hoist speeds of up to 100 m/min and a 40-tonne grab curve in A7 classification or 34-tonne grab curve in A8 classification and can handle ships up to the Panamax class. And its compact design, “makes it versatile as possible and no larger than necessary,” explained Dobner.
“Those who think that Model 4 is merely a drawing board concept are mistaken,” said Dobner. “Indeed, in the last few months, the Model 4 has begun operating in ports in Belgium, Spain and India.”
In the port of Antwerp, for example, Gemeentelijk Havenbedrijf commissioned a G HMK 6407 Model 6 Mobile Harbour Crane in spring 2007 and, at the same time opted to purchase a Model 4 G HMK 4406 that went into service in mid-September handling containers and general cargo. And on December 4, 2007 a similar unit was handed over to Terminales Maritimas de Galicia in the Spanish Port of Ferrol, where it is currently mainly handling wind power plant components
The latest news is that India’s Navayuga Engineering Company Ltd (NEC) has just ordered two Model 4 G HMK 4406 mobile harbour cranes to handle containers and bulk materials in the Port of Krishnapatnam, 180 km north of Chennai.
“We are certain that, with the Model 4, we have introduced the right entry-level model for harbour crane operators who require 100-tonne lifting capacity,” Dobner concluded.
