Dusty,
Full hoist rope length including rope to rig the jib and maintain 3 wraps is approximately 310-320m. At 30m of HUH, the crane would need approx 220m of rope in total to work in 4 part. You might, therefore, remove about 100m of rope if you discover that the rope is not reeving properly at the lesser operating mast and HUH height.
