I have now received your inquiry. In general we as others can not show all arm positions in our lifting diagrams � Fly jib diagrams actually shows more arm positions than a diagram for a crane without Fly Jib (see attached examples also explaining about the ISO curves). In general the crane safety system will help you from lifting more than rated capacity in crane as well as on Fly Jib. The two positions you have sketched: Position1 will be 1500kg Position 2 will be app 700kg. Please remember� the given arm positions are just an indication of arm positions as lifting with max rated capacity will mean a considerable deflection of the crane structure. Lifting diagrams in general do not show this, but it is included in the lifting capacities and the eventual ISO curves. Lifting in high arm positions and not using a winch the pivoting around any of the pivoting points using main boom, second boom or fly jib lifting cylinder would mainly tilt the fly jib hook to the side as you will have to use also the extension cylinder to lift vertically. The extension capacities are limited to not compromise the structure stability. In practical life it means that you can lift from the ground to any position safely and under control of the safety system. Lifting down from high positions with near vertical it is possible to tilt and partly lift a much too heavy load. The safety system will stop you and you can put the load down and use a bigger crane.. this is normal lifting loads of limited size from platforms (roofs or floors). If however you manage to loosen for instance a top part of an antenna from its base and it comes into free air being much too heavy for the crane the arm system can collapse.
