inclined planes
A common type of simple machine found at the back of a truck is a ramp. Ramps make it easier to load and unload heavy items by allowing them to be rolled or pushed up an incline rather than lifted directly. This reduces the amount of force required to move objects.
An inclined plane, of course! All of the moving companies use ramps (a type of inclined plane) to unload and load their trucks.
A roller conveyor is a very simple device. It often used to temporarily link a loading dock to the bed of truck, so that boxes slide quickly from one to the other (in either direction). A permanent installation only requires a frame, usually at the appropriate height for ease of use.
Yes, it uses many different "simple machines", including wheels and at least one lever on a fulcrum.
Depends on the quarry. Some haul by truck, some haul by a conveyor belt.
I believe that the trowel is a wedge and an inclined plane, but I don't know if it also qualifies as a lever.
