In launching its new Model 2, Gottwald is not merely introducing the first member of its Small Crane Family, it is also launching a new crane type at the same time – the G HRK Rubber-Tyred Portal Harbour Crane
Düsseldorf, 12 June 2012 – In launching its Model 2, Gottwald Port Technology GmbH, a subsidiary of Demag Cranes, has produced a Harbour Crane that is specifically designed to meet the needs of smaller terminals in maritime and river ports. The new model has a maximum lifting capacity of 80 t, a radius of up to 40 m and hoisting speeds of up to 120 m/min. Model 2 is the first member of Gottwald's Small Crane Family, which has now extended Gottwald's Generation 5 Harbour Cranes into the realms of smaller cargo handling cranes.
While this launch heralds the new crane model as a whole, Gottwald has chosen to use the occasion to introduce a new crane type, the G HRK Rubber-Tyred Portal Harbour Crane. According to the company, this crane type combines the mobility of the classic rubber-tyred G HMK Mobile Harbour Crane with the benefits attached to a drive-under portal solution, such as that offered by the G HSK Portal Harbour Crane. Alongside these types, Gottwald also offers the new Model 2 as a Floating Crane (G HPK Harbour Pontoon Crane or as the G HSK Portal Harbour Crane on a barge) with individually tailored barges and as the fixed G HPK Pedestal-Mounted Harbour Crane. "Our Model 2 fully meets the demand for a versatile handling machine constructed specially for smaller maritime and river ports. At the same time, the launch of the new G HRK crane type further cements our pioneering reputation in Harbour Cranes based on proven Mobile Harbour Crane technology" enthuses Giuseppe Di Lisa, Head of Port and Intermodal Cranes at Demag Cranes. "By combining the diversity of crane types and variants on the one hand with our Advance Order Programme on the other, we are able to offer customers tailored solutions and short delivery lead-times. This is a concept that terminal operators all over the world are benefiting from." continues Di Lisa.
Gottwald crane families
Gottwald's Generation 5 consists of three crane families. After the company introduced its Large Crane Family, consisting of the high-performance Models 6, 7 and 8, at the beginning of 2006 on the occasion of the market launch of Generation 5, it then added its Models 4 and 3 in 2007 and 2010 respectively to expand the range of cranes through the Medium-Sized Crane Family, which is designed for standard requirements. With Model 2, the successor to the HMK 170, more than 150 of which were sold, the last of the Generation 4 models has now been replaced while, at the same time, presenting the first member of the Small Crane Family.
Specifications and performance data
With a maximum lifting capacity of 80 t, radius of up to 40 m and hoisting speeds of up to 120 m/min, Model 2 offers considerably higher lifting capacity, an extension of the working radius by two metres and faster working speeds compared with its predecessor – the 63-t HMK 170 Mobile Harbour Crane – allowing it to achieve much improved handling rates. In comparison with its predecessor, there have been many changes in design and drive technology, such as AC powered hoists and slewing gear units. Potential customers interested in Model 2 can take advantage of a broad range of options to enhance ergonomics, productivity and environmental compatibility. These options include a particularly energy-efficient hybrid drive and equipment for hooking up to a quayside power supply.
Gottwald's new crane model is available to the market in three variants, two of which are 2-rope cranes and one a 4-rope grab crane.
The two 2-rope variants, equipped with a single hoist, can offer maximum lifting capacities of 63 t at up to 21 m and 80 t at up to 17 m radius. They are particularly well suited to handling containers and general cargo alongside barges, coasters and feeder vessels with up to eight container rows.
The 4-rope grab variant is equipped with a second hoist and, to ensure a long lifetime, has a 25 t grab curve for A8 classification (and 32 t grab curve for A7). This crane is designed for professional, tough handling of a broad range of bulk materials including coal, ore, agribulk and biomass alongside barges, coasters and Handysize vessels. It has a maximum lifting capacity of 63 t and a radius of up to 38 m.
New crane type – G HRK Rubber-Tyred Portal Harbour Crane
The crane types in Gottwald's Generation 5 already in existence have now been supplemented on the occasion of the market launch of Model 2 with the G HRK Rubber-Tyred Portal Harbour Crane fitted with a mobile drive-under portal. The proppable standard portal with a propping base of 12.5 m x 11 m, a clearance height of 6 m and a clear width of 9.5 m, allows ample space for terminal transport vehicles to pass underneath it. This ensures that HGV and railway traffic or, alternatively, conveyor belts, can operate beneath the crane.
Thanks to its rubber tyres, the G HRK Rubber-Tyred Portal Harbour Crane is itself mobile and can be travelled to its next job site. To this end, the portal has four axle alignments with two subframes each, which can be steered at up to 40° for crab steering, tight turning circles and even on-the-spot turning. According to Gottwald, this guarantees good manoeuvrability even on very narrow quays and, as a result, fast, easy positioning alongside the vessel.
The spacing between each pair of the four axle alignments is 2.1 m. The 4.2 m spacing between the two inner axle alignments means there is room for a fifth if necessary while retaining the spacing between axle alignments of 2.1 m, so the G HRK Rubber-Tyred Portal Harbour Crane can also be used on quays where the infrastructure only permits lower loadings, e.g. when travelling the crane.
