Question

when hauling a load in a dump truck, the dump body must be lowered and placed into what control position?
float
store
hold
lift

Explanation:

When transporting a load with a dump truck, the lowered dump body needs to be secured in a position that prevents unintended movement. The "Hold" control position locks the hydraulic system to keep the body in the lowered, stable state during travel, while the other positions serve different functions (Float allows free movement, Store is not a standard dump truck control term for this purpose, Lift raises the body).

Answer:

Hold
