TOC Europe 2010, Valencia (Spain), June 8, 2010 – – In launching its Model 3 Harbour Crane, Gottwald Port Technology GmbH (Gottwald), a subsidiary of Demag Cranes AG, has expanded its current range of Generation 5 Harbour Cranes. As the successor to the Generation 4, HMK 260, the new Model 3 takes over the slot as the entry level model for the 100-tonne class in Generation 5.
"With its Model 3 Harbour Crane, Gottwald has launched yet another future orientated handling machine," explains Dr. Mathias Dobner, Executive Vice President and Member of the Executive Committee of Demag Cranes AG responsible for R & D / Engineering. "This crane has improved working speeds and a greater radius than its predecessor, and it also features innovative drive technology and design, such as the 3-phase-powered hoist and slewing gear units and a broad range of options, including an energy-efficient hybrid drive. All in all, Model 3 is a handling machine that is designed to combine high handling rates with excellent efficiency, which means that it is an ideal extension to the existing family of Generation 5 machines."
After Gottwald initially launched its Generation 5 family of cranes at the beginning of 2006, consisting at that time of models 6, 7 and 8, the large crane family, the company then added its compact Model 4 at the end of 2007 as the next step towards filling the medium-sized family.
In line with the company slogan, "You Name it, We Crane it", Gottwald's Generation 5 Harbour Cranes offer maximum lifting capacities of 200 tonnes, working radii of up to 56 metres and are constructed using a ground-breaking modular design principle as Mobile Harbour Cranes, Portal Cranes, Floating Cranes on barges, combinations of Portal and Floating Cranes and pedestal-mounted cranes.
The numerous types and variants available, on the one hand, and the company's Advance Order Programme, on the other, ensure that customers are provided with individual solutions while minimising delivery lead-times and the specific investment costs for the machine and quay infrastructure. The many terminal operators all over the world who have bought the hundreds of cranes since the introduction of Generation 5 have benefited from this concept.
Entry into the 100-Tonne Class – High Working Speeds, Large Radius, Excellent Efficiency
With its broad range of 100-tonne Harbour Cranes, Gottwald meets the requirements of all types of vessels, terminals and cargo handling. As the entry model in this class, Model 3, with its maximum lifting capacity of 100 t up to a radius of 20 m, is the youngest addition to Gottwald's medium-sized crane family, which is characterised by its compact, functional construction and quick, easy access routes for crane personnel. Model 3 cranes are particularly suited to rapid container and general cargo handling alongside vessels up to standard class. For handling bulk materials, this new Gottwald universal machine has a 34 tonne and 28-tonne motor grab curve with A7 and A8 classification respectively.
With its maximum radius of 46 m, an installed maximum output of 895 kW and hoisting speeds of up to 120 m/min, Model 3 demonstrates a radius 2 metres more than that of its predecessor, the Generation 4, HMK 260, and increased working speeds to enable improved productivity.
Model 3 is available in three variants, and, as usual with Gottwald Harbour Cranes, as a rubber-tyred Mobile Harbour Crane, a rail mounted Portal Harbour Crane, a Floating Crane on a barge and as a pedestal-mounted stationary crane.
Proven Technology Coupled with Innovations in Design and Drive Technology
To ensure safe, ergonomic, economical and environmentally compatible crane operation, Model 3, like all the Generation 5 machines, is equipped with numerous practical enhancements as standard, backed up by a range of optional features. These include individually steered axles, tight turning circles and crab steering to provide optimum manoeuvrability and automation features for repetitive motions like propping the crane.
The optional load guidance system including linear load motion, load antisway, point-to-point handling and hoisting height limiting, assist the crane driver in achieving high handling rates.
"In line with our philosophy of blending proven technology with innovation, Model 3 continues our tradition of using field-tested, reliable Gottwald Harbour Crane technology together with many new features," enthuses Dr. Dobner.
Gottwald is also pioneering new drive concepts by using 3-phase-powered hoist and slewing gear units. "In this field, we are taking full advantage of technical progress and economic efficiency in 3-phase technology for drive motors of a size suitable for these applications," says Dr. Dobner. Added to this are the changes to the crane's construction which take into account the very compact design of Model 3, such as the new, space-saving hoist drive.
Electrical Drives, Of Course
Like all of Gottwald's Harbour Cranes, Model 3 also uses electricity as its energy source – which is the most popular form of energy in ports and terminals due to its cost effectiveness and environmental friendliness. The on-board diesel-powered generators meet the requirements of EU Directive 2000/14/EC and provide optimum efficiency, low fuel consumption and minimum exhaust gas emissions on the site.
As one would expect, Model 3 can also be powered from an on-shore power supply, which improves the efficiency of the machines still more. Crane owners benefit both from the energy recovered from the crane's lowering and braking motions and from the fact that exhaust gas emissions from the crane are zero and noise emissions in the terminal are also reduced.
First Time – Three-Phase Technology for Hoist and Slewing Gear Units
With the new Model 3, Gottwald is expanding its electric drive concept by employing 3-phase technology for its hoists and slewing gear units. "As the pacesetter in Mobile Harbour Cranes and their drive technology, Gottwald has for years been using reliable DC drives for its hoists and slewing gear units in cranes of all sizes," explains Dr. Dobner. "By now employing 3-phase current, we are integrating technology that has proved itself in numerous industrial applications and in mobile handling machines of corresponding sizes."
The advantages include:
-regular maintenance of carbon brushes no longer required
-reduced power surges for the generator due to the sophisticated design
-simplified integration of energy storage media (ultracaps)
-mitigated line-side harmonics in power supplies.
New Hybrid Drive – Future Orientated and Sustainable
If the local quay infrastructure does not allow the Model 3 crane to be connected to an external power supply, the new, optional Gottwald hybrid drive is the key to improved efficiency, reductions in fuel consumption in a double-digit percentage range and lower exhaust gas emissions. A further benefit of the new hybrid drive is that the diesel engine has quieter running characteristics, which reduces noise emissions.
In Gottwald's hybrid drive – a combination of an on-board diesel-powered generator and electrostatic short-term energy storage – the energy recovered during the crane's lowering and braking actions is stored and then made available to the crane's power system for the next work cycle. The short-term storage medium is provided by electrostatic wear and friction free double-layer capacitors (ultracaps), which store the energy as electricity so it does not have to be converted, have a high efficiency rating, power density and cycle rate, which makes them ideally suited to the tough conditions of professional crane operation. Together with the hybrid drive, the use of dynamic brake resistors improves energy management by producing significant fuel savings.
More Choice for Crane Operators
"The launch of Model 3 makes a further universally applicable, electrically powered handling machine available to the market. Electric drive technology from Gottwald stands for maximum energy efficiency – particularly the use of external power which increases the machines' efficiency and the use of the new hybrid drive open up a new field of potential cost reductions coupled with sustainable environmental protection," emphasises Dr. Dobner. "As the technological leader in this field, we are convinced that our new Model 3 is a milestone – not just in the many facetted 100-tonne cargo-handling segment, but also in terms of energy management, which is playing an ever more central role when it comes to our customers making investment decisions."
