Title Slinging of concrete pipes with steel ropes (choker or basket hitch)
Original title Anschlagen von Betonrohren mit Stahlseilen (Schnürgang, Hängegang) [in German]
Bibliographic information Dec. 1979, Vol.91, No.12, p.856-865. Illus. 3 ref.
Abstract The safety requirements for slinging large-diameter concrete pipes using a single or double choker hitch, or a basket hitch, with or without a spreader beam, are analysed: holding strength of the sling, lowest position of the pipe in the sling and angle formed by the sling legs, use of connecting hardware (rings, shackles, hooks), sloping position of the pipe during lifting. Lifting of pipes by choker hitch without a spreader should be avoided on account of the accident hazard. Appended are calculations permitting determination of the holding and elongation forces of ropes, and of the lowest position of the load in the sling.
