End Lifting sling angle range for Series 1 Containers.
The sling geometry for single point end lifting is effective over an angle range between 68° and 72° typically at 70°. The sling arrangement determines the head room and normally do not make contact with the end face of container but the top lifting point may be below top of high cube units and with some machines, may make contact with the end of container without being a problem.
For the sling assembly, the vertical distance T from aperture center (For Preston Lugs) to top lifting point in terms of sling angle α is:
T = ( P/2) tan α
Clearance h between lifting point and top of container is:
Clearance h above top of container.
Negative values are below top.
Chain lengths not given because of range of ancilliary devices available.
