Posted By A Campbell Are you asking for uk law..or is this abroad? Other consideration would be compensating for heave/swell and snatch of load... 0.5 ton may be rapidly more depending on shock load if you have a not got a calm sea state?

Posted By Robert K Lewis Your load is within the SWL of the spreader but! You will also need to look at the crane capacity at the load radius required in the context of your lift plan. You sound as though you are not too sure on this and I think that you might be best advised to get an engineer involved. You will need to look at where the crane can be located and that the swl of the crane is not exceeded at the radius to place the load in position. This in turn means a balance between possible locations, ground bearing capacity and crane size. With this size load I anticipate at least a 150 tonne crane or even larger if you cannot get close enough. The lift plan should make all of this clear. Incidentally I would be looking closely at the training of the slinger/signaller with the load so close to the spreader capacity. Bob
