When moving a load through a quadrant, what must the operator know?

• A. Total weight of the load
• B. The shutter speed of the crane
• C. Maximum load allowed in that quadrant
• D. The color of the load

Answer: (C)

Moving a load through a quadrant changes the crane’s safe lifting capacity because the geometry of the lift—radius, boom angle, and the load’s path—affects how much weight the structure can safely support at that moment. The operator must know the maximum load allowed in that quadrant so the lift stays within the crane’s rated capacity for that position. If you don’t know this, you could overload the crane as it moves, risking equipment damage, tipping, or a dropped load. Load charts are used to determine this limit, accounting for dynamic factors like movement and sway. The other options don’t provide information about the safe limit for that specific position, and color or unrelated specs aren’t relevant to capacity.
