Note: This diagram shows the lifting height under no load without consideration of deflection of the jib.
Operate the crane with a load in the jib angle range of 0° to 76°.

• A load is hung with four wires in all cases.
• The load which can be actually lifted is the difference obtained by subtracting the weight of the hook and hanging tools, such as slinging wire ropes (hook weight: 80 kg), from the rated total load.
• It is prohibited to lift a load while running on the track.
