Munck travelling deck cranes

[peterredd]

Hi My Friends
Could some one explain Munck Travelling Cranes.. I have never heard of them and why are they not used any more...

I know i could look it up But i would rather hear from someone whom has worked on ships with this system....


Cheers

Hi Peter

Starting from NIL knowledge, my Google research seems to indicate that Munck is a brand and travelling deck crane is a type of product

See http://www.munckcranes.com/documents/guide-to-overhead-cranes.pdf

Evening

I have only seen munck gantry's on ships specially built for forest products trade. The layout of these ships is also special, wide, square hatches with no combings to enable majority of cargo to be drop-stowed into position. Combined with the gantries whose rail mountings and travelling arms enable pinpoint drop-stowage, cargo damage is minimised, some gantries also have covers for weather protection. They also enable heavier lifts of over 20 mt more safely and faster than conventional means. Gearbulk, Star Bulk, Westfal-Larsen, Saga are some of the specialist operator of these ships, while operators in other bulk trades seem to opt for cheaper pedestal cranes to handle the not so tender bulk cargoes.

As Brent has outlined, Munck loaders feature regularly on open-hatch cargo ships, which have packaged timber as one of their principal cargoes but can can also carry containers and bulk cargoes.
In 1969/1970, Sweden's Johnson Line introduced a series of container ships fitted with these travelling gantry cranes. At that time, containerisation was in its infancy and many ports had not yet installed shore-side container handling equipment. Within a few years of entering service, the ports served by the Johnson liners had all introduced their container cranes so the Munck loaders were removed. This allowed containers to be stacked higher on deck, thus increasing the ships' TEU (Twenty-foot Equivalent Units) container capacity.

First time i have heard of the term was yesterday when Bob posted a photo of the MARGARET JOHNSON... I thank you all for your response.. I will also do a little research...

Munck was just one vendor of traveling gantry cranes, and Johnson Line just one of several ship lines to put them on their early container ships. The very first Sea-Land cellular conversions of 1957 had traveling gantries for self loading/unloading, as did most Sea-Land conversions through 1965 and even some lengthened in 1969. The very first new-built cellular ship, the KOORINGA, had gantries. Other lines that used gantries on at least some of their early container ships included APL, American Export-Isbrandtsen, Grace, Hamburg Sud's Columbus Line, K-Line/Pheonix Container Line/OOCL (same three ships), and British Yukon Navigation.

Other lines used a pivoting crane mounted on a traveling gantry, including Ben Line, DAL, Maersk, Nedlloyd, Woermann, and the CAROL Line ships of Hapag-Lloyd, Harrison Line, CGM, and KNSM.
