Which statement about cab-controlled cranes is true?

Which statement about cab-controlled cranes is true?

• A. They have no depth perception issues
• B. They can have depth perception difficulties and view obstructions with larger loads
• C. They are always safer
• D. They require no training

Answer: (B)

In cab-controlled cranes, what the operator sees from inside the cab can be limited or distorted, especially when the load is large. The load itself, the crane structure, and the hook can block the operator’s line of sight, creating blind spots and making it harder to judge how far the load is from targets or obstacles. The larger the load, the more pronounced these view obstructions and depth-perception challenges become. That’s why the statement about depth perception difficulties and view obstructions with larger loads is true. Other statements don’t fit: there can be depth-perception issues at times, so “no depth perception issues” isn’t accurate; cab operation isn’t inherently safer in all situations, so “they are always safer” isn’t right; and operators must be trained, so “they require no training” is incorrect.
