Zitat: | Vorech postete First such cranes were built after the second war. This hydraulic type was first installed up to undercarriage Opel Biltz - 3tons - cca in 1948. Also up to Škoda 6S6T and next unknown undercarriages. It was privat company "Horák and Hlava Prag" and after communist putsch this company was liquidated and complete production was given to ČKD in 1952. First crane on Tatra 111 undercariage was installed in 1954 - the type was HOJ 4. After that it was HSC4, HSC5 etc. JV |
This is sensational! It seems nobody in the West knows about it.
Around the same time the first hydraulic cranes started off in the West, like Grove, and also Hydrocrane from Milwaukee Hydraulics Corporation (later Bucyrus), but these were really very early stages.
Hydraulic excavators only followed during the 50-ies.
Thanks and best regards! |
