NOTES :
1. The mass of the hook (30 kg), slings and all similarly used
load handling devices must be added to the mass of the load.
The above numerical values of rated lifting capacities are
based on crane strength only.
The rated lifting capacities based on stability may lower than
those in the above table depending on the loading conditions
and the types of the chassis. SPEC, SHEET No, 1M+302-4-002,
