During transformer replacement, why must the gin pole height be carefully set?

• A. To minimize visual obstruction
• B. To avoid a two-block situation
• C. To prevent cable wear
• D. To reduce crew fatigue

Answer: (B)

Setting the gin pole height correctly keeps the load line from forming a tight angle that can let the upper and lower blocks come into contact during lifting. If the pole is too short, the blocks can collide or the line can ride up and jam, creating a two-block condition where the blocks lock together and the line cannot be reeved or released. This dangerous situation can cause loss of control of the load, line damage, or equipment damage. Proper height ensures the line path stays clear of the blocks and provides enough take-up and clearance for a safe lift.
