Ratings according to Japanese Construction Codes for Mobile Cranesand Japanese Safety Ordinance on Cranes, etc.2. Ratings in metric tons for 360 working area.3. Operating radius is the horizontal distance from center of rotation to avertical line through the center of gravity of the load.4. Weight of hook block(s), slings and other load handling accessories isincluded in rated load. Their total weight must be subtracted from ratedload to obtain weight that can be lifted.5. Ratings shown are based on freely suspended loads and make noallowance for such factors as wind effect on lifted load, ground conditions out-of-level, operating speeds or any other condition that could bedetrimental to the safe operation of this equipment. Operator, therefore,has the responsibility to judge the existing conditions and reduce liftedloads and operating speeds accordingly.6. Ratings are for operation on a firm and level surface.7. At radii and boom lengths where no ratings are shown on chart, operation is not intended nor approved.8. Boom inserts and guy lines must be arranged as shown in the“Operator's Manual”.9. Boom hoist reeving is 12 part line.10. Gantry must be in raised position for all conditions.11. Boom backstops are required for all boom lengths.12. Ratings shown inare determined by the strength of the boomor other structural component.13. Instruction in the “Operator's Manual” must be strictly observed whenoperating the machine.14. Crane boom ratings: Deduct weight of main hook block, slings, and allother load handling accessories from crane boom ratings shown.15. Auxiliary sheave ratings for crane boom: Deduct weight of ball hook,slings, and all other load handling accessories from auxiliary sheave ratings shown.16. Crane boom lengths for auxiliary sheave mounting are 15.2 m to 61.0 m.17. Crane boom ratings with auxiliary sheave: Deduct 0.8 ton from craneboom ratings shown. Minimum rated loads must exceed 2.0 ton.
