Laydown buckets, used where the charging height is low, differ from cylindrical buckets in that they:
Answer & Solution
Correct answer: C.
1. Where the mixer can only charge from low height, a vertical cylindrical bucket cannot be filled at all.
2. The laydown bucket sits on its long side during filling, exposing a wider opening.
3. When the crane lifts the bucket, the body turns through 90 degrees to the upright pour position.
4. The discharge gate remains on the bottom of the upright body.
5. So the defining geometry is the 90-degree rotation on lift, not the plan shape or material.
