The book is a civil engineering handbook on winch and cable systems. The
handbook may be used as textbook for university studies in civil
engineering and forestry and as the basis for studies in schools on a
technical level. It should be a useful reference book for construction
engineers, civil engineers, logging engineers, foresters and leaders of
operational activities under difficult terrain conditions. The content
in the book is based on more than 35 years experience with practical
winch and cable operations. As a leader of the Norwegian Institute of
Forest Operations, the author has carried out research work in this
field since 1947. The Institute is the owner of yarders, winches, cable
cranes etc., and with its own cable crews the Institute operates as a
contractor in its own research forests as well as in other state or
privately owned forests throughout Norway. The research work also
includes other cable crane operations in Norway and other countries. As
the leader of the Joint FAO/ECE/ILO Study Group on Mechanized Forest
Operations the author studied cable operations in most of the Eastern
and Western European countries. As president of the International Union
of Forestry Research Organizations the author visited most forest
countries in the world. Information from research and practical cable
crane operations were collected. The handbook is based on material on
winch and cable systems used in Japan, New Zealand, Soviet Union,
Central Europe, Northern Europe, Eastern United States, Western United
States and British Columbia.
