The crane represents two firsts for Gottwald. It is the first in a new line of small mobile harbor cranes, the Small Crane Family range. Gottwald says the new range is intended to extend its Generation 5 cranes down into smaller cargo handling applications.

It is also the first crane on which Gottwald has used rubber tyres on a portal crane. This, Gottwald says, will give crane operators the mobility of classic rubber-tyred mobile harbour cranes, while allowing dockside users the ability to drive under the gantry. Gottwald calls this new crane type the G HRK line, matching its G HMK designation for habour mobile cranes.

The 80t Model 2 is designed for smaller marine and river terminals. It lifts to a radius of 40m. It can hoist at speeds up to 120m/min.

As well the as the G HRK configuration launched with the new crane, Gottwald will also offer standard configuration options as a floating crane, a G HPK harbour pontoon crane, or as a fixed G HPK pedestal mounted harbour crane. Gottwald also offers the mounted crane on individually tailored barges.

The Model 2 harbour crane comes in three variants, with two provided as two-rope cranes, and one as a rope grab crane.
Gottwald said the two-rope version’s capacities are well suited to handling containers and general cargo alongside barges, coasters and feeder vessels with up to eight container rows. With a single hoist they lift up to 63t at up to 21m radius and 80t at up to 17m radius.

The four-rope grab is designed for handling a broad range of bulk materials including coal, ore, agribulk and biomass alongside barges, coasters and Handysize vessels. This crane has a maximum lifting capacity of 63 t and a radius of up to 38 m.

Gottwald intended to extend the lifetime of the Model 2 by adding a 25t grab curve for A8 classification and 32t grab curve for A7. It comes with a second hoist.

Compared with its predecessor, the 63t HMK 170 mobile harbour crane, it offers higher lifting capacity, a working radius extended by 2m and faster working speeds for improved handling rates.

Gottwald also made changes in design and drive technology, adding AC powered hoists and slewing gear units.
Options are available to enhance ergonomics, productivity. Fuel efficiency is enhanced by the energy efficient hybrid drive and equipment for hooking up to a quayside power supply.

Giuseppe Di Lisa, head of port and intermodal cranes at Demag Cranes, Gottwald’s direct parent company, said this was a pioneering design:

"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."
