When tank cleaning with a portable machine, how is the weight of the machine is suspended?

🔍 Key Concepts

• Portable tank-cleaning (Butterworth) machines and how they are positioned in a tank • Difference between supporting/suspending weight vs. controlling swing/rotation (tag lines) • Common suspension methods used for equipment lowered through deck openings on tank vessels

💭 Think About

• Which item in the choices is specifically designed to carry the vertical load of a piece of equipment rather than just guide or steady it? • Think about what actually goes through the Butterworth opening and what stays on deck when lowering a portable cleaning machine. • Which options sound more like control or safety accessories (to prevent swinging or twisting) rather than the main load‑bearing support?

✅ Before You Answer

• Identify which choice would most likely be the primary load-bearing member that actually holds the machine’s weight. • Separate in your mind what is used to lift and suspend versus what is used to guide, control, or secure hoses. • Eliminate any option that would reasonably be weakened or unsafe under the full weight and dynamic movement of a tank-cleaning machine.
